　　Complete equipment for oil-based mud treatment in Huabei Oilfield

　　The North China Oilfield oil-based mud processing project is located in Hebei Province. During the production process and at the bottom of the oil tank, oil-based mud is generated, requiring equipment to discharge 12-22.5t/h of slag per hour. Due to the rudimentary mud treatment facilities and failure to handle it in a timely manner, it has caused environmental pollution in the factory area.

　　Basic properties of oil-based mud:

　　Oil based mud wastewater contains a large amount of sediment and requires reduction treatment, mainly to remove or reduce pollutant factors such as SS. According to on-site investigation and analysis, ① the effluent requirements are not high; ② The mud generated at the bottom of drilling and oil tanks mainly contains a large amount of suspended solids (mud) and is accompanied by rock debris; ③ Contains very small amounts of other soluble substances

　　To prevent environmental pollution, ensure normal production and sustainable development, and protect the surrounding water environment, the company attaches great importance to the issue of waste mud pollution and is determined to treat the waste mud. We have entrusted our company to develop a treatment plan. Our company adopts advanced waste mud treatment technology and equipment based on the properties and requirements of drilling mud and tank bottom oil mud, with the goal of reducing the cost of waste mud treatment projects and operating costs. Based on this principle, this governance plan document has been formulated for review by the leaders of the enterprise and relevant departments.

　　Basic principles for the design of complete equipment for oil-based mud treatment:

　　1. Choose a wastewater treatment and reuse process that is mature in technology, easy to operate and manage, and has low operating costs.

　　2. The selected wastewater treatment and reuse process should adapt to the requirements of fluctuations in water quantity and quality.

　　3. Choose equipment with reliable quality, low consumption, and easy maintenance to reduce operating costs.

　　4. The overall layout is compact, beautiful, and reasonable.

　　5. Avoid secondary pollution and minimize the amount of sludge generated as much as possible.

　　Based on the properties of oil-based mud and its characteristics; In order to ensure that the treated waste mud meets the requirements for dry discharge, and based on the combination of economic, social, and environmental benefits, as well as the technical level of wastewater treatment at home and abroad and our company's design and construction practice experience, we have selected“Horizontal centrifugal dewatering machine+The governance process route of the collection pool. This process has the following characteristics:

　　⑴ Low investment, low operating costs, and no secondary pollution;

　　⑵ The operation, management, and operation of the facilities are simple, with a high degree of automation and minimal maintenance;

　　⑶ Good processing effect, stable and reliable operation.

　　Detailed introduction of the core equipment of the complete set of oil-based mud treatment equipment (horizontal centrifugal dewatering machine)

　　The horizontal centrifugal dewatering machine uses a working speed higher than the standard centrifuge to achieve a higher separation factor, achieve more efficient separation, obtain higher clarity of the supernatant, and greatly improve the solid recovery rate. Our company has conducted in-depth research on the principles and structural structures of centrifuges and developed a full range of high-speed centrifuges, which can meet the material separation requirements under different working conditions and are the choice for solid-liquid separation.

　　The material is transported to the spiral discharge port through the feeding pipe, and is evenly distributed on the rotary drum through the high-speed rotating spiral discharge port. The main motor drives the rotary drum to rotate at high speed, generating thousands of times centrifugal acceleration. Solid particles quickly deposit and accumulate on the inner wall of the rotary drum, and the spiral conveyor, which moves relative to the rotary drum, continuously transports the sediment to the sediment discharge port. Under the joint action of the extrusion of the spiral conveyor and the dehydration section of the rotary drum, the moisture of the solid particles is removed as much as possible. The separated clear liquid is freely discharged through the gravity of the weir plate or discharged under pressure by the centrifugal pump provided by the equipment. By controlling the speed of the differential input shaft (the back drive device includes a constant torque variable frequency motor, coupler, hydraulic motor, etc.), the speed difference (i.e. differential speed) between the screw conveyor and the drum can be adjusted to control the slag discharge speed and separation performance.
