Problems solved by technology
[0002] In the existing technology of oil exploitation, during the construction process of oil well ash injection, agent plugging, sand washing, etc., due to various reasons, the oil pipe is injected to death by mortar, that is, the phenomenon of oil pipe stuck or commonly known as flagpole is common. Accidents, no matter what measures are taken to remedy the accident, there will always be some oil pipes in the oil well on the ash surface, which will bring great difficulties to future construction. It usually takes more than one month for the oil pipe and ash plug in the oil well to stay, which not only affects the production of the oil well, but also causes huge losses to many other aspects

Embodiment Construction
[0012] As shown in the figure, in the oil pipe in the oil production well ash injection plugging construction involved in the present invention, the lower end of the oil pipe 1 is provided with a pipe string 2, and the pipe string 2 is connected to the lower end of the oil pipe 1 through a pipe series connector 3. The pipe string 2 and the pipe string connector 3 are made of high temperature resistant soft metal material.
[0013] More specifically, the pipe string 2 and the pipe string connector 3 are made of non-ferrous metal aluminum or copper.
[0014] The length of the pipe string 2 is 60-120 meters, and is composed of several pipe string sections 4. The length of each pipe string section 4 is 4-10 meters, and each pipe string section 4 is connected through the pipe series. The sets of 3 phases are connected as one.
[0015] The lower end of the pipe string 2 is provided with an open pipe series adapter 5, and the open angle of the open pipe series adapter 5 is 60-120 de...

Abstract
The present invention relates to an oil pipe used in grouting construction of oil production well. The lower end of the described oil pipe is equipped with pipe string, and the described pipe string is connected with lower end of the oil pipe by means of pipe string coupling sleeve. The described pipe string and pipe string coupling sleeve are made up by using high-temperature resistant flexible metal material. Said invention can greatly raise productivity of oil production well, and can reduce energy source consumption.
Description
technical field [0001] The invention relates to the field of petroleum exploitation, in particular to an oil pipe in ash injection plugging construction of an oil production well. Background technique [0002] In the existing technology of oil exploitation, during the construction process of oil well ash injection, agent plugging, sand washing, etc., due to various reasons, the oil pipe is injected to death by mortar, that is, the phenomenon of oil pipe stuck or commonly known as flagpole is common. Accidents, no matter what measures are taken to remedy the accident, there will always be some oil pipes in the oil well on the ash surface, which will bring great difficulties to future construction. When the oil pipe and ash plug in the oil well are stuck, it generally takes more than one month, which not only affects the production of the oil well, but also causes huge losses to many other aspects. Contents of the invention [0003] The purpose of the present invention is t...
