How to make the use of mud safe, environmentally friendly, economical and effective, has always been a major course in drilling production.

Problems encountered at the drilling site: Mud is called "drilling blood". Oil-based mud mixed with oil, water, organic clay and chemicals can effectively reduce frictional resistance, reduce accident rates, and improve well quality , It is widely used in the construction of horizontal wells and deep vertical wells. In the past two years, the use of oil-based mud by drilling crews has increased, and the consequent increase in costs and safety and environmental protection issues have become increasingly prominent. In addition, due to the lack of oil-based mud and cuttings processing equipment, drilling engineering companies are very passive in bidding for foreign projects. Therefore, the drilling waste disposal system just solves this problem.

Working principle of drilling waste treatment equipment:

After the discarded drilling mud and cuttings are returned from the wellhead, they directly enter the device, and are conveyed to the cuttings dryer through the sealed long pipe-screw conveyor, and are rotated by the dryer and filtered by the screen. Most of the dried cuttings are discharged from the first sand outlet along another screw conveyor, and the remaining liquid mud is pumped into the centrifuge to be subdivided, and the fine cuttings are finally separated Discharge from the second sand outlet. At the same time, the treated mud is re-injected into the mud tank through the pipeline and recycled again.

The composition of drilling waste treatment equipment: drill cuttings dryer, high-speed centrifuge, screw conveyor, mud tank.

Advantages of drilling waste treatment equipment:

1. In the past, the discarded drilling mud was directly discharged into the mud pool, and then a dedicated person would do harmless treatment such as dosing and mixing, which was not only costly, but also took a long time. The use of the drilling waste treatment system not only can reuse the mud, but also realizes on-site treatment, which saves time and effort.

2. The cuttings processed by the drill cuttings dryer can be directly pulled and transported, reducing transportation costs.

3. The dried cuttings can be used to pave roads for recycling.
