Mud Circulation Treatment System Generated During Drilling

Oilfield drilling mud is a working fluid that lubricates, cools, protects arms, transmits drilling cuttings and balances bottom pressure during oilfield drilling. Drilling waste mud consists of a small amount of mud discharged during drilling and a large amount of mud discharged after completion. The main components are bentonite, drilling cuttings, water and various chemical additives. Because the waste mud contains a variety of toxic and harmful pollutants such as alkali, salt, oil, etc., it is difficult to deal with, so oily sewage and dirty oil are called the three major public hazards in oil fields. With the provisions of the national environmental protection law and the enhancement of people’s awareness of environmental protection, the petroleum industry has stepped up scientific research on elimination, utilization and resource recycling.

During oil drilling, the use of drilling mud treatments is frequently involved. Untreated sludge can have serious environmental impacts if it is not treated effectively. Relevant practitioners need to properly implement various drilling mud measures and optimize scientific and technical means, so as to effectively improve the quality of oilfield mud treatment. Therefore, in the process of oil drilling, it is necessary to recycle the mud generated during the drilling process to ensure the smooth progress of the drilling work and the engineering quality of the drilling construction.

KOSUN’s mud zero discharge equipment is suitable for mud treatment in medium and large construction sites. The advantages of this model are the large processing capacity, the low moisture content of the mud cake, and the high degree of automation. The filter cake can be accumulated for a certain period of time, which improves work efficiency and reduces costs.

Reservoir dredging sludge dewatering treatment equipment

The following is a detailed introduction to the five commonly used treatment equipment for reservoir dredging sludge dewatering:

The ideal method for front-end sludge dredging treatment is to use a submersible sand pump as a dredging pump and a cutter suction dredger and a scour suction dredger. The method often used in the back-end sludge dewatering treatment is to use a special sludge treatment system to separate the solid and liquid of the sludge from the sludge from the front-end dredging. The system mainly includes: screening equipment, dosing system, Sludge dewatering equipment, etc. Among them, sludge dewatering equipment can be prepared with 3 different types of equipment according to different actual conditions of reservoir sludge, including: screw stacker, centrifuge, filter press:

1) The submersible sand pump is used as the dredging pump, and the corresponding sand pumping system and special sand conveying pipeline can be used for easy cleaning. The overall configuration is simple to operate, easy to use and economical.

2) Adopt cutter suction dredger and scour suction dredger. It is mostly used in situations where the area of the reservoir is relatively large, the dredging sediment is relatively hard, or the requirements for the depth of dredging are relatively strict. Suction type dredging vessel, simple to operate, low investment, mostly used in small reservoirs, the sediment is not very hard and can be recoiled with high pressure water, and the depth requirements for dredging are not very strict.

3) Snail stacking machine: The snail stacking machine has the functions of rapid concentration, continuous dehydration and self-cleaning. The advantage of the screw stacking machine is that the equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, so that the It avoids the common clogging problem of traditional dewatering machines, and also achieves the purpose of sufficient sludge dewatering.

4) Filter press: The basic principle of solid-liquid separation is: the mixed liquid flows through the filter medium (filter cloth), the solids stay on the filter cloth, and gradually accumulate on the filter cloth to form a filter cake. The filtrate part penetrates the filter cloth and becomes a clear liquid without solids. The plate and frame filter press is used for the separation of solid and liquid. Compared with other solid-liquid separation equipment, the mud cake filtered by the filter press has higher solid content and excellent separation effect.

5) Centrifuge: It uses the principle of centrifugal sedimentation to separate the suspension in the sludge. The smaller the particles, the slower the sedimentation and the more serious the diffusion phenomenon. Therefore, the powerful centrifugal force of the centrifuge is used to accelerate the sedimentation of the particles in the liquid. The speed of these small particles can overcome the diffusion to produce a sedimentation process, so as to achieve a rapid dewatering process of the sludge slurry. The progress of the sludge dredging and dewatering project in the reservoir is generally subject to time requirements and limitations. Stable and efficient treatment equipment can well ensure the smooth completion of the reservoir sludge dredging and dewatering project according to quality and on time.

Drilling waste mud treatment is currently a major problem in oil fields

Waste drilling mud is one of the main pollution sources in the oil and gas industry, and its waste disposal is currently a major problem that plagues oil fields.

The oilfield drilling waste mud treatment process is the immediate disposal of waste drilling mud (drill cuttings) while drilling, meeting the requirement of “mud zero discharge”, reducing land use and reducing environmental pollution. This technology is to change the “end treatment” to “full process control”, the waste mud is diluted-flocculated-separated into three parts: cuttings, mud cake and water, and the solids in the mud are treated by water washing, flocculation separation and chemical reaction. Make the cuttings and mud cake meet the discharge standard. After the harmful components and chloride ions in the mud are separated into the water, they are dehydrated by vacuum adsorption or extrusion to make mud cakes. At the same time, the waste water separated by centrifugation is subjected to air flotation. The sedimentation, filtration system, and reverse osmosis system are used for concentration treatment. After treatment, the up-to-standard wastewater can be reused for drilling recycling.

The main equipment for the treatment process of waste oil drilling mud includes: drying shale shaker, drill cuttings dryer, drilling fluid centrifuge, screw conveyor, screw pump, etc. KOSUN’s mud zero discharge system can effectively control the water content of drilling cuttings (6%-10%) in the drilling mud, stabilize the liquid phase performance, and achieve the purpose of zero discharge of the mud.

There are many kinds of waste mud treatment processes in oilfield drilling. Each treatment solution needs to be determined according to the drilling site and drilling construction conditions. It must not only achieve the treatment effect, but also meet the national environmental protection requirements, and strive to achieve harmless treatment. It plays an active role in improving and protecting the environment, soil and groundwater.

Why is it difficult to dehydrate and separate water-based mud from oilfield drilling?

The main factor that is difficult to dehydrate and separate water-based mud for oilfield drilling is the complex nature and many components of hydraulic mud.

The product composition of water-based mud in the drilling process is more complicated. The main components of oilfield drilling mud are multiphase colloids such as water, clay, drill cuttings, flocculants, and drilling fluid additives. Chemical agents such as bentonite, weighting agents, inorganic salts, baseless polymers, organics, synthetic polymers and surfactants are often added in the configuration to improve the performance of water-based muds. Groundwater, drill cuttings, clay, etc. that are collected when drilling into the formation in the oil field. Its pH value is a little alkaline, generally 8.15-9.10, the moisture content is usually between 35% and 90%, and the solid phase particle size is generally between 0.01μm2 and 0.1μm2.

The properties of oilfield drilling mud are related to underground structures and rock properties. As the drilling depth increases, the downhole structure becomes more complicated, and the corresponding mud performance requirements and chemical configuration become more complicated. The corresponding pollutants in the solid waste discharged outside are also increasing, the content and the concentration are also increasing. Therefore, it is difficult to dehydrate and separate the water-based mud in oilfield drilling, and it will affect the quality and progress of the drilling project in severe cases.

Oil-based drill cuttings reduction processing system

Oil-based drilling cuttings is a kind of oilfield drilling fluid, also called oil-based mud, which includes oil as the continuous phase, water volume content up to 50% as the dispersed phase, emulsifier as stabilizer and water-in-oil emulsified drilling fluid and A drilling fluid usually made of diesel oil, oxidized asphalt, organic acids, alkalis and other chemical agents. Oil-based drilling fluid has the advantages of high temperature resistance, salt and calcium corrosion resistance, and is beneficial to the stability of the borehole wall, good lubricity, and less damage to the oil and gas reservoirs. At present, it has developed into an important method for drilling high-temperature wells, deep wells and other high-difficulty wells and various complex formations, but the preparation cost is much higher than that of water-based drilling fluids.(Oil-based drill cuttings reduction processing system)

Oil-based drill cuttings treatment usually adopts a special “oil-based drill cuttings zero discharge system“. The system is composed of screw conveyors, drill cuttings dryers, environmentally friendly centrifuges and other equipment, supporting the mud solids control system to achieve mud processing while drilling, replacing the traditional methods of using filter presses or mud tanks, greatly improving economic and environmental benefits, it is widely used in oilfield drilling.

After the oil-based drilling cuttings pass through the special oil-based mud zero discharge treatment system, it can process 40 tons of oil-based drilling cuttings per hour without adding any chemicals. The oil-base oil content of the drilling cuttings is controlled by 5% to 8%; the well is truly realized. “No pooling”, “reduction” and “zero emissions” and “zero additions” requirements for the field.
