An oil mining sand filter device

Abstract

The invention discloses a sandstone filter device for oil exploitation, the structure of which comprises: a slag discharge pipe, a sieve plate sliding sand filter, an oil delivery pipe, a pressure gauge, a drainage pipe, a recoil rotary filter tank, and a punching horizontal tank. It realizes the use of the sieve plate sliding sand filter to cooperate with the oil delivery pipe, and the oil delivery pipe is inserted into the inclined frame connection pipe in the tank shell to transport the oil to the extraction pipeline, so that the mesh filter is matched with the pipeline during the transportation process, through the sliding clamp The filter brush plate and the piston cylinder screen frame form a gradient staggered groove fluid layered processing filtering effect, and the later piston cylinder screen frame forms a sorting sand and gravel operation, which is convenient for the fine separation of thick stones and fine sand, and improves waste reuse Value, guarantee the feedback bagging of sand and gravel for use in construction, and oil can be purified and processed after mining, which is convenient for the dredging of pipeline transportation in the later stage, and after avoiding solid plugging in advance, the uniform flow quality of the oil film is improved to facilitate the transfer of fluid saturation.

Description

technical field [0001] The invention relates to a sandstone filter device for oil exploitation, which belongs to the field of machinery. Background technique [0002] Oil exploitation cooperates with pipeline transportation to form a mechanical processing line in the mining area, extracting useful minerals and fluid raw materials to form post-processing contact mechanical equipment use and preparation, and also to obtain effective filtration, screening and impurity removal effects for continuous finishing and purification after oil exploitation. Disadvantages to be optimized in the current technology are as follows: [0003] The entrained sand and gravel after oil extraction will cause a sudden increase in the gas density of the fluid due to solid-state collisions, resulting in oil bubbles in the gas trapped in the fluid. Solid plugging occurs, which affects the branching of the flow in the pipeline and auxiliary treatment operations, interferes with the overall filtration ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a sand and stone filter device for oil exploitation, so as to solve the problem that the entrained sand and stone after oil exploitation will cause a sudden increase in fluid gas density due to solid collision, resulting in the generation of gas trapped in the fluid. Oil bubbles, during the transportation process, oil bubbles are easy to stick to the sputtering delivery pipeline, causing the accumulation of oil residue and sedimentation, resulting in solid sand and gravel plugging, which affects the flow branch and auxiliary treatment operations in the pipeline, interferes with the overall filtration fineness, and also causes Drainage oil soaking phenomenon, resulting in oil film plugging combined with sand and gravel plugging to scratch the inner wall of pipelines and tanks, and slow down oil production
