Drilling waste management

Drilling waste management technology at home and abroad at present, mainly include simple processing emissions, safe injection formation or well annular space, long-distance centralized processing, backfill, pit sealing, land farming, curing, a solid liquid separation, burning, microbial treatment, etc. However, these methods are basically a problem, economic and environmental benefits can’t be both satisfactory on treatment effect and the processing cost. If it contracts low cost, then environmental requirements cannot meet the requirements.

KOSUN drilling waste management services are based on our Waste Management Hierarchy which governs the way we deal with solids control and waste disposal in all our drilling activities worldwide. The four levels of this basic hierarchy is reduction at source, recycling, treatment and disposal, in that order. To ensure that these steps are well implemented, precise planning for both environmental protection as well as cost-effectiveness is pivotal. This involves studies to review both the project and the disposal criteria which need to be customised for specific requirements.

EPB TBM waste mud treatment equipment

EPB TBM waste mud treatment equipment is the equipment who is supported the Earth Pressure Balance Shields to treat  the mud which is produced when constructing. So called Earth Pressure Balance Shields (EPB) turn the excavated material into a soil paste that is used as pliable, plastic support medium. This makes it possible to balance the pressure conditions at the tunnel face, avoids uncontrolled inflow of soil into the machine and creates the conditions for rapid tunnelling with minimum settlement.

The special feature of Earth Pressure Balance Shields is that they use the excavated soil directly as support medium. This method is the first choice in cohesive soils with high clay and silt contents and low water permeability. A rotating cutting wheel equipped with tools is pressed onto the tunnel face and excavates the material. The soil enters the excavation chamber through openings, where it mixes with the soil paste already there. Mixing arms on the cutting wheel and bulkhead mix the paste until it has the required texture. The bulkhead transfers the pressure of the thrust cylinders to the pliable soil paste. When the pressure of the soil paste in the excavation chamber equals the pressure of the surrounding soil and groundwater, the necessary balance has been achieved.

KOSUN EPB TBM waste mud treatment equipment is the most advanced technolog ical products in the world. It can meet the environ mental requirements on urban construction and processing. It can aso save construction costs, reduce mud emissions and reduce environmental pollution. It is an economical, efficient and environment-friendly necessary construction equipment.The market demand of environ mental EPB TBM waste mud treatment equipment will be increasing.

Drilling Fluid Performs Many Important Functions

Functions of a Drilling Fluid:
The mud system in a drilling operation performs many important functions. These include:

Drilling Fluid
Drilling Fluid

-Clean beneath the bit: To maximize drilling efficiency, the drilling fluid must translate hydraulic horsepower from the main mud pumps into enough velocity to remove drill cuttings away from the face of the bit and allow the cutters to be in contact with the formation. If the cuttings are not removed, they will be ground into smaller particles and adversely affect drilling rate, mud properties, and project costs.

-Carry drilled solids from the bottom of the hole to the surface: Once cuttings are removed from beneath the bit, the fluid must transport them toward the surface faster than they can settle back toward the bottom of the hole.  Factors which influence cuttings movement are velocity, cuttings size and shape, and the fluid properties.

-Suspend cuttings when circulation is stopped: Circulation of the drilling fluid stops periodically during operations, such as when making a bit trip.  The drilling fluids must be able to suspend cuttings and weighting material while circulation is stopped, but should begin to flow easily when the pumps are switched back on.  Properties which affect cuttings suspension are the density and viscosity of the mud and the density of the solids in the mud.

-Allow removal of cuttings by the surface system.
-Control formation pressures.
-Promote borehole stability.
-Cool the bit and lubricate the drill string.
-Help support the weight of the drill string.
-Allow accurate information from the well.

Mud is the common name for drilling fluid.  While it is outside the scope of this handbook to offer a detailed discussion of drilling fluids, a brief outline of the general characteristics of drilling fluids is included to establish the basic relationships between drilling mud and solids control.  Similarly, any discussion of solids control would be incomplete without establishing an understanding of the nature of mud solids — their size, shape and composition.

Zero Discharge on Drilling Waste Management

Zero Discharge on Drilling Waste Management Operating principles:
Water-base mud cuttings enter the top hopper of vertical centrifuge and fall onto its internal separation area. The internal cone rotates at a high speed of 900RPM and generates a centrifugal force of 430G. For density difference between liquid and solids, mud is hurled out of surface of drilling cuttings and passes through screens, and solids are retained inside the screens. And then, liquid is discharged from the liquid outlet and dry solids are discharged from the bottom of equipment.

Drilling Mud Zero Discharge Treatment Process

Brife introduction of drilling mud zero discharge treatment process:

1.Collection Unit. Through the solid control equipment, drilling waste mud enter into the screw conveyor, while adding water for dilution and mixing. Then through screw conveyor, the mud enter into the sand and gravel separation & washing and stirring device, after stirring, washing and spiral separation, a large number of inorganic particles, small rocks, cuttings can be separated from the drilling mud, which reduced the influences of type of material on the follow-up treatment. So that the abandoned mud can maintain the good liquidity. After the separation, the mud lifting into the slurry storage tank by the mud pump, while adding treatment chemicals, after stirring and mixing reaction, the mud lifting into the second processing unit the pump.

2.Solid-liquid separation unit. In order to reduce the moisture content and the pollutants of the mud cake, it is indispensable to add the treatment chemicals and the multiple stirring and washing. After the pharmaceutical treatment and repeated mixing and washing, the contaminants contained in the mud are washed into the water. If there is petroleum pollutant, it needs to be treated by the oil removal device first, and then the oil is recovered. The de-oiling mud is sent to the centrifugal extension by the pump for mud and water separation, and the solid matter in the mud can be discharged after the separation. The separated water enters the collection tank and then pumped by the pump to the third treatment unit.

3.Wastewater treatment unit. After centrifugation, the content of suspended solids in the water is relatively high. Through the flotation and filtration system, the suspended solids contained in the water are removed, reducing the organic content in the waste water and then enter the reverse osmosis system for concentration. Reverse osmosis out of the standard wastewater into the reuse water tank, pump back to use for the production. A small amount of concentrated liquid can also be treated by evaporation crystallization, salt can be sold to salt chemical manufacturers, turning waste into treasure.

The above is the whole drilling Mud Zero Discharge Treatment Process.

Strategy to Manage Solid Waste

The Government are committed to sustaining a healthy environment and a vibrant economy. Consistent with this commitment, there has been a fundamental shift in the way we view solid waste. It is now recognized that solid waste is a resource that can result in the creation of jobs through cost effective and environmentally responsible management. The Strategy to Manage Solid Waste will include these benefits:

Bans on the disposal of beverage containers, corrugated cardboard, newsprint, scrap tires, used oil, lead-acid batteries, waste paint, automotive antifreeze, glass food containers, steel/tin cans, selected plastics and compostable organic materials.

Expansion of the current deposit/refund system on beer and liquor bottles to include all beverage containers with the exception of milk. Milk containers will be recycled through province-wide collection programs.

The number of active landfills will be reduced by approximately 75 percent. Currently, there are 40 active landfills in the Province. All landfills will have to meet the Department of the Environment’s new stricter guidelines to prevent leachate and other problems associated with the current variety.

In order to ensure that cost increases are minimized, municipal units will be encouraged to cooperate on a regional scale. It is recommended seven solid waste resource management regions be established.

The Strategy will involve diversion of 60 to 70 percent of household hazardous waste from disposal facilities.

In a consumer society, most commodities, once no longer used for their intended purpose, have traditionally been discarded. The implications of this “throw away” mentality are profound. In recent years, people have begun to recognize these implications and have taken aggressive action to change their practices and attitudes towards waste.

Reducing the amount of waste we generate, identifying opportunities for the recovery of valuable resources, encouraging the development and commercialization of new technologies, and taking necessary action to secure a sustainable future are among the challenges we face today and in the years ahead.

Drilling Mud Recycling System Overview

Mud plays a very important role in drilling operations. Therefore, mud generated during the operation must be treatment by drilling mud recycling  system to achieve a certain degree of recovery and purification, which is not only conducive to environmental protection, but also can greatly reduce operating costs.

In some specific drilling operations, mud recovery and purification is particularly important, such as trenchless operations. At present, the relevant domestic enterprises have made great achievements in the technology of the non-dredged drilling mud recycling system. For example, KOSUN non-dredged driling mud recycling system is in the leading position in terms of quality and performance.

Drilling mud recycling and reuse system is to make a rough purification through shale shaker, and then through the hydrocyclone, centrifuge equipment for filtration and purification. The filtered solid particles can be used as a filler in the construction, water can be used to irrigate the farmland.

With the increasing requirements for oilfield clean production, the role of mud recovery and purification is increasingly important. Especially in the non-dredged mud treatment, the non-dredged driling mud recycling system is a very important part of the progress of the project. Trenchless driling mud recycling system can not only meet the engineering waste mud treatment requirements, to achieve clean production, but also can greatly reduce production costs.

KOSUN can provide its clients with three series products, including solid-control equipment for oil and gas drilling, centrifuge series and drilling waste treatment equipment. They are widely used in oil and gas drilling, coalbed methane drilling, shale gas Drilling, water wells, geothermal well drilling, horizontal excavation of horizontal directional engineering, gravel grading mine, tailings treatment, river clean-up project, industrial wastewater treatment, environmental sewage treatment, waste oil recovery purification treatment and other fields.
