Abstract

The invention discloses a layered water injection distributor which is convenient for salvaging plugs, and relates to the technical field of oil field exploitation equipment. The invention includes an upper connecting pipe, a working pipe, a lower connecting pipe and a blocker, wherein the blocker is a split structure, including a hydraulic plate, a water injection pipe and a blockage plate, and an electromagnetic plate is welded at the lower end of the water injection pipe, which is magnetically attracted to the blockage plate structure. In the present invention, by setting the plug into two parts separated from each other, it is convenient to reduce the overall weight of the plug when the plug is salvaged, so that the hydraulic pressure in the pipeline can push out the hydraulic plate and the water injection pipe and float up for recovery and salvage; In the legacy pipeline, it forms a one-way valve structure with the support bolt inside the lower connecting pipe, which can repeat the water injection cycle and meet the normal work of oilfield exploitation; among them, by setting the guide rod and slide pipe in the working pipe, using both The electrical connection relationship with the electromagnetic plate controls its magnetism and separates it from the plugging plate, which facilitates the salvage and recovery of the plugging device.

Description

technical field [0001] The invention belongs to the technical field of oil field exploitation equipment, in particular to a layered water injection distributor which is convenient for salvaging plugs. Background technique [0002] In the layered water injection work of oilfield exploitation, in order to realize the layered water injection of oil fields with different depths, the lower water distributor is usually required to infiltrate and inject water into the area; the existing water distributor for layered water injection needs to be The lower plug is used to block the oil pipe, so as to realize pressurized water injection; but after the work is completed, the plug needs to be salvaged in time so as not to affect the subsequent oil field production work; when the water injection is performed again, the lower plug still needs to be repeated; as we all know, water distribution The plug is usually installed at the design depth, frequently lowering the plug to salvage will in...
