Research and Application of Cleaning Construction Systems for Oil Wells
As a response to the common problem of hydraulic channel clogging during the seating process of hydraulic isolation devices in the Linpan oilfield production operation,a clean construction system has been developed and designed.This system consists of two integral components:a sediment filtration device for hydraulic isolation devices and an anti-blocking oil sleeve balancing valve.Notable features include its simple structural design,cost-effectiveness,robustness,adaptability,reusability,and easy scalability.The system has been put into practical use in the Linpan oilfield in 2012,with an approximate annual application rate of 80 wells,and has not encountered any cases of hydraulic channel blockage.The system has become an indispensable tool for the construction of the sealing layer associated with the"Y445-type hydraulic isolation device"in the Linpan oilfield,thereby establishing a standardized construction protocol.Its implementation has yielded significant application benefits and holds great promise for widespread adoption and use in the construction of hydraulic isolation devices in various oilfields nationwide,underscoring its great potential for widespread application.
