High-efficiency filtering petroleum screen pipe

Abstract

The invention discloses a high-efficiency filtering petroleum screen pipe. The screen pipe comprises a screen pipe body, a dismounting plate and circular fixing racks. The lower half portion of the screen pipe body is provided with a trapezoid groove. The dismounting plate is arranged in the trapezoid groove of the screen pipe body. The multiple groups of rectangular clamping grooves are excavatedin the inner side top end surface of the screen pipe body. The circular fixing racks are inserted into the rectangular clamping grooves of the screen pipe body. The inner side bottom end surface of the dismounting plate is provided with an arc-shaped groove. The bottom ends of the circular fixing racks abut against the curved-surface inner wall of the arc-shaped groove. Four groups of circular threaded holes are drilled in the screen pipe body. Four groups of circular through holes and four groups of circular grooves are excavated in the dismounting plate. The adjacent circular through holesand the circular grooves are connected. Bolts are connected in the circular threaded holes in a threaded connection mode. The bolts pass through the inner cavities of the circular through holes. The high-efficiency filtering petroleum screen pipe can high-efficiently filter petroleum and can be conveniently dismounted and replaced, and a suitable range is widened.

Description

technical field [0001] The invention belongs to the technical field of petroleum screen pipes, and in particular relates to a high-efficiency filtering petroleum screen pipe. Background technique [0002] At present, pipe fittings used in petroleum, chemical, electric power, shipbuilding, metallurgy, machinery, textile, food, construction, pharmaceutical and other industries need to have high strength, pressure resistance, corrosion resistance, and high temperature resistance. Therefore, in petroleum In the field of mining technology, in order to improve the recovery rate of crude oil in the oil field, secondary oil recovery and tertiary oil recovery are usually carried out. a special pipe. However, the structure of the current oil screen is too simple, and the strip or hole-shaped screen is generally processed on the surface of the pipe, and some screens are made of stainless steel wire wound after punching. The function of the current screen is too simple. , can only car...

Problems solved by technology

However, the structure of the current oil screen is too simple. Generally, strip or hole screens are processed on the surface of the pipe, and some screens are made of stainless steel wire after drilling. The function of the current screen is too single. , can only carry out sieving operation, but cannot carry out normal conveying work, and cannot meet people's needs
