Aiming at the long-term research on the technical solution of the UAE oilfield drilling waste management, this article gives the specific solution of drilling waste management during the drilling process.
As we all know, the UAE’s petrochemical industry is developing rapidly, and a large amount of waste mud will be generated in the process of oil exploration and drilling. These actions have caused a great damage to the surrounding air, soil and water environment. Brightway has provided long-term technical support to oilfields in UAE for drilling mud treatment. In the whole process of technical guidance and equipment operation, it can not only be very useful to solve the environmental problems, but also can do recycling to the waste of the solid control system. This series drilling waste management is compose of the Dryer shaker, vertical cuttings dyer , decanter centrifuge, mud tank and screw conveyor, etc..
The main process of drilling waste management:
- Solid-liquid separation and waste recycling stage: The mud in the drilling process is transported to the drying shaker, and the drying shaker filters out the larger solid particles. Then pump the mud into the desander and desilter to separate the solid and liquid from the sand and mud, and remove the sand gravel in the mud. The treated mud flows into the mud tank and waits for further processing.
- Mud waste drying stage: After acheiving solid-liquid separation of drillng cuttings, the leachate recovered can be dried by the drill cuttings dryer. Most of drill cuttings be discharged from the first outlet of cuttings dryer and then the remaining mud will be processed again through the centrifuges. Cuttings after drying can be used to pave and make bricks.
The drilling waste management technical solutions of Brightway in the UAE oilfield fully demonstrate the following advantages:
A：Less land occupation: Slurry ponds reduce the occupied area and save a certain amount of land area occupation cost for oilfield companies.
B：Environmental & Economical: The drilling waste management and cutting dryer system realizes the social value of environmental protection, maximizing the usage of drilling fluid economically;
C: Low cost & Remarkable effect;
The cuttings separated by this technology can be discharged according to national requirements, and can be used as road paving and brick making. The separated liquid can be recycled to achieve waste utilization, energy saving and emission reduction.
Overall application of drilling waste management to oilfield eliminates the pollution essentially. In response to the complex situation of the UAE oilfield, Brightway provided specific drilling waste management solution, and it has a positive impact on the UAE oilfield, also it brings comprehensive economic benefits.
