Bottom water injection device for tight oil layer exploitation

The utility model discloses a bottom water injection device for tight oil reservoir exploitation, which belongs to the technical field of tight oil reservoir exploitation and comprises a water injection pipe body, a connecting component is mounted at one end of the water injection pipe body, two through holes are formed in one end of the water injection pipe body, and an anti-blocking component is mounted at the other end of the water injection pipe body. A plurality of strip-shaped grooves are formed in the other end of the water injection pipe body. According to the anti-blocking water injection pipe, blockage in the water injection pipe can be better prevented when the water injection pipe is inserted, a better anti-blocking effect is achieved, meanwhile, the anti-blocking water injection pipe can be quickly disassembled and assembled and adjusted according to the depth of a water injection layer, and a better disassembling and assembling effect is achieved. 本实用新型公开了一种致密油层开采用底部注水装置，属于致密油层开采技术领域，包括注水管本体，所述注
