Problems solved by technology
[0003] Common high-pressure resistant multi-pipe layered water injection devices usually have fixed water injection pipes, but this kind of fixed water injection pipe can only be used for water injection at a specific position in actual use, which is not convenient for users to inject water according to actual needs. The real-time adjustment of the position brings limitations to the use of the device, and at the same time, it is easy to cause accidents due to the wrong water injection level. Therefore, a high-pressure resistant multi-pipe layered water injection device is proposed.

The invention relates to the technical field of water injection devices, and discloses a high-pressure-resistant multi-pipe layered water injection device which comprises a water tank, a pressing plate is movably connected into the water tank, a sealing ring is fixed to the periphery of the pressing plate, a connecting sleeve is fixed to the axis of the surface of the pressing plate, and an adjusting rod is movably connected into the connecting sleeve. A crank is fixed to the top of the adjusting rod, a first nut is fixed to the joint of the adjusting rod and the water tank, a water adding pipe is fixed to the outer wall of the water tank, a water outlet pipe is fixed to the bottom of the water tank, and an outer cover is fixed to the outer side of the lower portion of the water outlet pipe. And a rotating shaft is fixed at the joint of the water outlet pipe and the outer cover. According to the high-pressure-resistant multi-pipe layered water injection device, through the movable arrangement of the water injection pipe, a user can flexibly adjust the position of the water injection pipe according to the water injection requirements of different positions in the actual environment, and the use limitation of the device is reduced.
Description
technical field [0001] The invention relates to the technical field of water injection devices, in particular to a high-pressure resistant multi-pipe layered water injection device. Background technique [0002] The water injection device is a mechanical device that injects purified water into the oil layer from the ground in order to maintain the pressure of the oil layer and improve the recovery rate of the oil layer. In order to make the oil field continue to produce high and stable production and improve the ultimate oil recovery rate of the oil field, many oil fields at home and abroad use it. The method of injecting water into the oil layer to maintain the formation pressure and improve the recovery of the oil well. [0003] Common high-pressure resistant multi-pipe layered water injection devices usually have fixed water injection pipes, but this kind of fixed water injection pipe can only be used for water injection at a specific position in actual use, which is not ...
