Tubular-column-type sand control screen pipe

Abstract

The invention discloses a tubular-column-type sand control screen pipe. The screen pipe comprises a first connection pipe, a base pipe and a second connection pipe. The first connection pipe is arranged on a top. The bottom end surface of the first connection pipe is connected to the base pipe in a threaded connection mode. The bottom end surface of the base pipe is connected to the second connection pipe in the threaded connection mode. The periphery of the base pipe is provided with filtering grooves. The N groups of filtering grooves are uniformly arranged on the base pipe and the filteringgrooves pass through the inner wall of the base pipe. The inner wall of the base pipe is provided with an anti-compression device. The anti-compression device comprises a connection rod and an anti-compression circle ring. The connection rod is welded to the inner wall of the base pipe. The anti-compression circle ring is welded to the bottom end surface of the connection rod. The anti-compression circle ring is located on the inner end surfaces of filtering grooves. The height size of the anti-compression circle ring is smaller than the height size of each filtering groove. When the tubular-column-type sand control screen pipe is located at an underground layer, an anti-compression capability is high, an over-current area is increased and the screen pipe can be popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of sand control screens, in particular to a column type sand control screen. Background technique [0002] In the production process of oil and gas wells, sand control technology will directly affect the quality and production effect of oil and gas wells, and it is also related to the life of oil and gas wells. Therefore, sand control technology is very important in the production process of oil and gas wells, and promotes the continuous development of sand control technology It is necessary to continuously innovate the sand control tools and their supporting processes. Among them, the most commonly used sand control tool in the process of oil and gas well exploitation is the sand control screen, which can block the sand particles in the formation output from the sand control screen through the sand control screen. It plays a very good purpose of sand control, so as to prevent the pump from being stuck due t...

[0002] In the production process of oil and gas wells, sand control technology will directly affect the quality and production effect of oil and gas wells, and it is also related to the life of oil and gas wells. Therefore, sand control technology is very important in the production process of oil and gas wells, and promotes the continuous development of sand control technology It is necessary to continuously innovate the sand control tools and their supporting processes. Among them, the most commonly used sand control tool in the process of oil and gas well exploitation is the sand control screen, which can block the sand particles in the formation output from the sand control screen through the sand control screen. Play a very good purpose of sand control, so as to prevent the phenomenon of pump jam caused by sand production in oil wells. The current sand control screen is easily damaged by the pressure of the underground layer in the underground layer, resulting in difficulty in mining
