Soluble water nozzle

Abstract

The invention relates to the technical field of oil field oil recovery, and discloses a soluble water nozzle. The soluble water nozzle comprises a connecting pipe; one side of the connecting pipe is fixedly connected with a fixed sleeve, and the outer surface of the fixed sleeve is movably sleeved with a sealing ring; one side of the fixed sleeve is movably sleeved with a water nozzle, and a connecting block is welded on one side of the front surface of the water nozzle; a hollow groove is formed in one side of the front surface of the connecting block, and one side of the top of the hollow groove is movably sleeved with a limiting block; one end of the limiting block extends into an inner cavity of the hollow groove; a clamping block positioned in the inner cavity of the hollow groove isfixedly mounted at the bottom of one side of the limiting block; and the bottom of the limiting block is fixedly connected with a spring. Through cooperation of the limiting block, the clamping blockand the spring, the soluble water nozzle is convenient for preferable connection of the connecting pipe and the water nozzle, so that the problem of more difficult replacement of the damaged water nozzle caused by a welding fixation mode in the fixing process of the water nozzle and the connecting pipe is solved, and the connecting effect is improved.

Description

technical field [0001] The invention relates to the technical field of oil recovery in oil fields, in particular to a soluble faucet. Background technique [0002] Subdivided water injection of water injection wells is the key to stabilizing oil production and controlling water in oilfields. At present, most water wells are multi-layer subdivided water injection. For the compression type layered water injection string packer, it needs to be lowered into the dead water nozzle first when the packer is released. After the release is successful, pull out the dead water nozzle and put it into the matching water injection nozzle. In this way, the process will be complicated due to the release of the packer during on-site operations, and downhole accidents such as pulling out the steel wire and failing to catch the water nozzle will easily occur, and even cause operational problems. Rework, and at the same time, the faucets are connected by welding when they are connected to the wa...

Rework, and at the same time, the faucet is connected with the water injection pipe by welding, which leads to a more time-consuming disassembly of the faucet
