Sinopec News Network reported on September 17, Jianghan Petroleum Engineering Company took the lead in Sinopec to realize the centralized treatment of drilling and workover water-based cuttings, which increased the processing efficiency by 8 times and reduced the cost by 30%, and made every effort to build green drilling and workover to protect the ecological environment
.
During the drilling process, the use of drilling fluid can cool and lubricate the drill string and bit, form a filter cake on the borehole wall, reduce fluid leakage into the formation, balance formation pressure, stabilize the borehole wall, cleanly carry drill cuttings to the ground, and reduce formation pollution , Effectively improve drilling timeliness and ensure safe production downhole
.
According to the country's environmental protection requirements for drilling production, the drilling process needs to be equipped with mud non-landing equipment, and the waste mud is treated in a harmless manner while drilling to realize resource utilization
In the previous water-based cuttings processing while drilling, water-based equipment was used to follow the well at the well site, and a water-based unit served one well
.
In the 50D workover team in the northwestern Xinjiang industrial area, due to the limited well site, it is not possible to implement mud non-landing while drilling services.
In the face of strict local government environmental protection requirements, the speed and quality of workovers are restricted
.
In order to solve this problem, Jianghan Petroleum Engineering Environmental Technology Service Co.
, Ltd.
put forward a plan for them to centrally treat the mud without landing
.
After more than two months of research, field survey, planning, site selection, and environmental review, a relatively concentrated location was selected to build a skid-mounted centralized processing station, and a special transfer vehicle was arranged to transport the water-based cuttings produced by each well Go to the processing station for centralized processing
The new mode of centralized processing is more in line with the requirements of local governments for environmental protection.
It not only solves the environmental protection problems of Party A's water-based cuttings treatment, but also saves the time of equipment relocation, installation, and debugging, which is faster and more efficient, and reduces personnel and equipment costs.
, Which can save costs for Party A and achieve mutual benefit and win-win results
