Intelligent water injection device for oil field water injection well

Abstract

The invention discloses an intelligent water injection device for an oil field water injection well. The intelligent water injection device comprises a filtering mechanism, a water storage mechanism,a water treatment mechanism and a water injection mechanism which are connected through a water injection pipe network, wherein the filtering mechanism comprises a water inlet channel, a filtering net, a water conveying channel, a sediment collecting tank and a floating object collecting tank, a vertical flat channel is formed in the tail end of the water inlet channel, the top end of the flat channel communicates with the floating object collecting tank through a floating channel, a sediment channel at the bottom end of the flat channel communicates with the sediment collecting tank, the middle of the flat channel communicates with a water supply channel, the filter screen covers the water supply channel, and the sediment collecting tank and the floating object collecting tank communicatewith a water source of incoming water through pipelines. According to the intelligent water injection device for the oil field water injection well, the interception amount of the filter screen is greatly reduced, backwash operation becomes possible, normal operation of the water injection device is guaranteed, and manual cleaning operation is reduced.

Description

technical field [0001] The invention relates to oil exploitation technology, in particular to an intelligent water injection device for oil field water injection wells. Background technique [0002] In the process of oil field exploitation, in order to maintain the pressure of the oil layer and increase the oil recovery, it is necessary to continuously inject water into the oil layer through the water injection device. The water injection device in the prior art generally includes a filter mechanism, a water storage mechanism, a water treatment mechanism, a water injection mechanism and The water injection network connecting these institutions. [0003] Among them, flowing water sources such as rivers, lakes and seas are often used as water sources for water injection because of their convenience and low cost. Before water injection, the flowing water sources need to be filtered through a multi-stage filter mechanism. Among them, the first-stage filter mechanism is generally...

AI Technical Summary

Problems solved by technology

Among them, when the mesh of the filter is set too large, a large amount of impurities will enter the next-level filter mechanism, which will bring a heavy burden to the lower filter mechanism, and if the mesh of the filter is set too small, it will be easily blocked. Due to the arrangement of the stage filter mechanism in the front, the impurities washed away by the backwash will soon adhere to the filter screen again, and the conventional desorption operation has little effect, so it must be cleaned manually frequently

[0004] In summary, the disadvantages of the existing technology are that, on the one hand, frequent blockages affect the normal operation of the water injection device, and on the other hand, manual cleaning is time-consuming and laborious
