Abstract

The invention discloses a temporary plugging agent conveying device for stratum temporary plugging steering in oil exploitation. The temporary plugging agent conveying device comprises a box body, a barrel body, a base, a stirring motor, a stirring shaft, a stirring rod, a lifting pump, a conveying pipe, a connecting pipe, a first heating pipe, a bottom plate, a feeding pipe, a shell, a conveying roller, a driving motor, a partition plate, a heat insulation plate, a second heating pipe, a fixed seat, a roller, a belt wheel, a belt, a walking motor, a hydraulic cylinder, a pressing plate, a discharging pipe, a pressure gauge, a fixed pipe, a shell, a piston, a through hole, a rotating block and a rotating handle. According to the temporary plugging agent conveying device, the barrel is arranged, so that the temporary plugging agent can be stored and can be fully mixed, the temporary plugging agent can be conveniently and rapidly conveyed after being mixed, and the temporary plugging agent can be conveyed by rotating the rotating handle; the pressurization effect can be improved through rotation of the conveying roller, and the temporary plugging agent can be conveyed at proper temperature and pressure; the rollers are arranged, so that the movement of the whole device can be realized, and the stability can be realized through the movement of the pressing plate after the movement is finished.

Description

technical field [0001] The application relates to the technical field of temporary plugging agent application, in particular to a temporary plugging agent conveying device for temporary plugging diversion in oil production. Background technique [0002] Temporary plugging agent is a substance that temporarily reduces formation permeability or temporarily plugs high-permeability oil layers. Temporary plugging agent is a substance that can temporarily reduce formation permeability or temporarily plug high-permeability oil layers. It is mixed with water-soluble polymers and then injected. In the well, under the action of pressure difference, a thin and dense oil layer temporary plugging zone can be quickly formed. After a certain period of time, it can be removed by itself or manually. According to its solubility and action principle, it can be divided into four types: acid-soluble temporary plugging agent, oil-soluble temporary plugging agent, water-soluble temporary plugging ...
