INTEGRATED DEVICE FOR PROCESSING productive strata

摘要

The invention relates to oil and gas industry for drilling and well operations, namely to the devices for opening and secondary acid treatment of productive formations in order to stimulate oil and gas production. The apparatus for integrated processing of productive formations, comprising a column mounted on the tubing jet pump and a packer, also mounted in the bottom of the column tubing perforator and perforator installed above the circulation valve, which serves to isolate and report internal cavity pump- tubing to the annulus and is opened (activated) resetting the corresponding diameter of the ball and the creation of pressure in the tubing and 5 MPa, at this m moves sleeve opens channels in the housing of the circulation valve. Thus, the proposed apparatus for integrated processing of productive layers reduces the flow resistance when pumping chemicals in the processing bottomhole zone of the well layers allows the lifting equipment at low levels in the borehole and low reservoir pressures and eliminates inertial component of the pressure in the tubing above the perforating gun when lifting the punch, without imposing piston punch, to improve the efficiency and security of the processing carried out productive strata operations. 4 yl. 2L
