Drilling mud solid control and waste management

Introduction of Drilling mud solid control system:

Solid control system is a technique used in a drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally, a solid control system contains five stages: the mud tank, shale shaker, vacuum degasser, desander, desilter, and centrifuge. The shale shaker is used to separate big solids with diameter above 75μm, the desander addresses solids from 45-74μm, and the desilter segregates solids between 15-44μm. Sometimes the desander and desilter are combined as one high efficiency mud cleaner. When air enters the drilling fluids, a vacuum degasser is used to separate the air. When there is no air in the mud, the degasser works as a big agitator. All these stages are mounted on the top of the mud tank. After separating the solids, the clean mud can be pumped into the borehole again.The mud system with 4 phases of solids control process can be understood as the 5 phase purification system. From shale shaker, vacuum degasser, to Desander cone, Desilter cone, and the decanting centrifuge: different working principle, different separation point. Every well drilling requires such a system to process drilling mud. However, per different well depth and different drilling conditions we’ll get different configurations and different results.

Introduction of Drillingmud waste management:

Drilling waste management system, also called as drill cutting treatment system or drilling cutting management system. According to different applications, it can be classified as water-base drilling waste management system and oil-base drilling waste management system.

The main Drilling waste management equipments are drying shaker, cutting dryer, decanter centrifuge, screw conveyor, screw pump and tanks. The drilling waste management system can effectively control the moisture content (6%-15%) and oil content (2%-8%) in drilling cuttings and stabilizes the liquid phase performance.

The elevated diesel tank is installed with explosion-proof floating-ball level switch.

The elevated diesel tank is installed with explosion-proof floating-ball level switch; KOSUN 40+5m³ elevated diesel tank is the special-purpose oil tank to provide and store diesel for power machines (diesel engine, generator, etc.) of drilling crew. therefore the centrifugal oil pump can deliver the oil in oil storage tank to elevated oil tank automatically. In case of low oil level, the explosion-proof level switch opens, the oil pump starts automatically and oil transportation begins; in case of high oil level, the explosion-proof level switch closes, the oil pump closes automatically, and oil transportation ends. In order to prevent failure of explosion-proof level switch, the equipment is especially installed with oil return pipe. In such a way, the oil will not overflow from the tank even under failure of level switch.

When elevated oil tank is lifted up, the oil pressure rises. The oil in tank will be transported to equipment requiring diesel at drilling site from three channels through filter and flowmeter, and it can also flow back to the oil storage tank. The oil consumed by equipment can be read out from pointer of flowmeter.

After the elevated diesel tank is installed, check to ensure that all valves are in corresponding states. Park the refueling truck beside the oil tank, connect the outlet opening with oil feeding buffer tank or inlet opening before opening it and choose to start the 50CYZ-20 centrifugal oil pump; pay attention to the rotation direction of the oil pump. After opening or closing corresponding ball valves, and starting the oil pump, the oil flows into oil storage tank through filter, flowmeter, pipeline, ball valve and centrifugal oil pump. With liquid surface rising, the column of magnetic reversible level meter display changes from white to red. The junction of white and red colors indicates the liquid level of oil storage tank.

KOSUN SP series shear pump is a centrifugal pump designed for quick configuration of drilling mud.

SP series shear pump can effectively mix and fully hydrate the added materials in the drilling fluid, save the use of mud materials, shorten the mud configuration time, provide good mud performance for the drilling process, is an ideal drilling fluid solid control equipment. The degree of dispersion and hydration of bentonite particles in water depends on: electrolyte content, time, temperature, number and concentration of surface replaceable cations in water. Other things being equal, SP series shear pumps can save bentonite by more than 30%.

SP series shear pumps allow the polymer to be diluted and hydrated as soon as possible. The high molecular weight of the polymer used in the mud is high, and it is not easy to hydrate directly, so the polymer needs to be pre-cut. The shear pump provides high shear efficiency and speeds up the dilution and hydration of the polymer, thus improving the quality and efficiency of the mud distribution.

Final disposal and utilization of sludgeⅠ

After sludge is treated and disposed by a series of methods, there are generally the following final disposal methods for the dried sludge:

1. Sanitary landfill

Sanitary landfill is a traditional and mature sludge disposal method with low investment requirements and good effect, and can also increase part of urban construction land. As for the dry sludge, it is generally selected to be buried together with the municipal daily household garbage through solid waste landfill, or special sludge landfill can be set up for it. However, the current sludge treatment technology is not very perfect, some harmful substances in the sludge may not be removed clean, after landfill may have a certain potential threat to the surrounding environment.

2. Incineration

Incineration is the most thorough way of disposal. Because sludge contains a lot of organic matter and fibrous lignin, it generates a lot of heat after incineration, and the residue is less, and does not need sterilizing treatment. The energy generated during incineration can be used to generate electricity, and the ashes after incineration can be used to make cement, etc. Incineration of sludge is a very effective way to dispose of sludge.
