Sand washing tool

Abstract

The invention discloses a sand washing tool which comprises an equipment main body, stop blocks, a sand washing pipe and a sand washing pen point, wherein the upper end of the equipment main body is provided with a sand washing liquid inlet; the side end of the sand washing liquid inlet is provided with a sand outlet; a regulating rod is arranged inside the equipment main body near the sand washing liquid inlet; the stop blocks are fixedly connected onto the outer surface of the regulating rod; a coil is arranged at the tail end of the regulating rod; the upper end of the equipment main body is provided with a well sealing device; and the sand washing pipe is arranged at the lower end of the well sealing device. The coil and the stop blocks are arranged in the sand washing tool; when the coil is electrified, the stop blocks are moved, and the sand washing liquid inlet is further opened; water enters the sand washing pipe through the sand washing liquid inlet; water flow can impact sandat the well bottom; the sand upwards moves through the circulation of the sand washing liquid; when the coil is deenergized, the sand outlet is opened; the stop blocks block the sand washing liquid inlet; the sand and the sand washing liquid in an oil well are discharged out from the sand outlet at the same; the work division is clear; the integral sand washing efficiency is improved; and the sand washing and the sand outlet can be performed at the same time.

Description

technical field [0001] The invention relates to the technical field of sand washing, in particular to a sand washing tool. Background technique [0002] Sand washing is a sand cleaning method that uses high-speed liquid to wash away the sand at the bottom of the well, and uses the circulating liquid flow to bring the washed sand to the ground. It often requires the use of professional sand washing tools for operation. [0003] Sand washing tools are common equipment in the process of deep well operations. Sand washing tools are needed in the process of restoring the normal production of some oil wells. There are many types of sand washing tools on the market, but these are now on the market When the sand washing tools of this type are in use, the sand washing liquid inlet and the sand outlet share the same interface. The sand washing and sand outlet cannot be carried out at the same time, and the use efficiency is not high. Therefore, there is an urgent need for technology t...
