The treatment of drilling waste is to control the water content of drilling cuttings in drilling mud.

The treatment of drilling waste is to control the water content of drilling cuttings in drilling mud, stabilize the performance of liquid phase, and achieve the purpose of dry treatment. The liquid phase can be used for secondary injection without destroying, so that the enterprises can expand the drilling scale without environmental protection worries.

The use of drilling mud not landing system eliminates the direct digging and circulating pool, reduces the land use, reduces the related costs, and reduces the workload of well crew. More importantly, once the system is put into use, it can not only realize harmless treatment of drilling mud and solid waste, but also recycle both of them, which is environmentally friendly and energy-saving. Mud pollution to the environment will be largely eradicated, so as to create a “green” logo, oil drilling exploration field to create greater social and economic benefits.

Solid liquid separation and waste residue recovery stage: drilling mud through the elevated manifold into the mud vibrating screen to remove large solid particles, and then sand pump pumping treated mud into the desander, desilter to remove sand and mud, mud treatment in the mud, the treated mud into the mud tank for further treatment.

The screw conveyor produced by xi ‘an KOSUN is used in the drilling waste disposal project.

The screw conveyor produced by xi ‘an KOSUN is used in the drilling waste disposal project, providing an effective and low-cost drillings transportation system for offshore drilling and land drilling devices. The screw conveyor adopts the combined structure of more than 12 feet in each section, which can be flexibly assembled and used in different drilling sites, with simple operation, stable structure, strong adaptability in working space and high safety performance. Thus, the working efficiency of the equipment is greatly improved and the cost and resources are saved. The screw blade of screw conveyor is made of wear-resistant material to ensure its service life.

When the screw shaft rotates, the material can only move forward along the bottom of the screw conveyor under the push of the blade due to the gravity of the material and the friction generated by the friction between the material and the tank wall, which is just like the translation movement of the unrotatable nut along the rotating screw. The movement of the material in the intermediate bearing depends on the thrust of the material moving forward behind it. Therefore, the material transport in the conveyor, is a complete slip motion. In order to make the spiral shaft in a more favorable tension state, generally will drive the device and discharge port on the same end of the conveyor, and the feed port as far as possible on the other end of the tail near. The rotating spiral blade moves the material and carries on the transportation, causes the material not to revolve together with the spiral conveyor blade the force is the material own weight and the screw conveyor casing to the material the friction resistance. According to the different materials, there are solid surface, belt surface and blade surface. The spiral shaft of the screw conveyor has a thrust bearing at the end of the direction of material movement. Intermediate hanging bearings should be added when the captain is longer.

The vc-1000 series vertical cuttings dryer produced by KOSUN is a vertical scraper discharge centrifuge.

The application of vertical cuttings dryer is currently at home and abroad to solve the drilling waste management in areas such as solid-liquid separation dryer mud treatment equipment, the traditional waste sludge treatment is used more pressure filter, but the operation is more troublesome, and the intensity of labor is big, cost is high, and drilling cuttings dryer is the modern solid-liquid separation, it does not need to add chemicals, cover an area of an area small, simple operation, low cost but also strong processing capacity, processing waste solid phase moisture content is low.

With the continuous improvement of national environmental protection requirements, major oil fields are faced with the problem of drilling waste disposal.

The vc-1000 series vertical cuttings dryer produced by KOSUN is a vertical scraper discharge centrifuge, which separates solid and liquid phases through centrifugal separation principle. Vertical cuttings dryer can effectively recover liquid components in cuttings, making solid phase transition very dry. It is suitable for water-based mud, oil-based mud and synthetic mud to recover the mud in cuttings, thus reducing drilling costs and environmental pollution. Its processing capacity is 40~60 tons per hour, and the liquid content/oil content of the treated cuttings is lower than 5%, meeting international emission standards and environmental requirements. It can be used for cuttings treatment in land and sea drilling.

While working, raise the support of driller to the highest place to meet the driller’s driller discharge. The centrifuge is placed on the tank body of the pry seat, and the discharged liquid part flows directly into the bottom collection tank. While drilling fluid is needed, it can be delivered via a delivery pump or connected to a tank of similar height.
