Abstract

The invention discloses formation water drainage equipment for oil exploitation, and relates to the technical field of oil exploitation auxiliary devices, the formation water drainage equipment comprises a fixed base and a mine ground, a drainage groove is formed in the top of the mine ground, the fixed base is movably connected to the bottom of an inner cavity of the drainage groove, and a stable insertion rod is fixedly welded to the bottom of the fixed base; and the stable insertion rod is movably connected to the interior of the mine ground. A rotating control motor is controlled to work to drive a hollow frame to rotate, then a filter cylinder is promoted to rotate around the circle center of the top of the hollow frame, and at the moment, under the action of centrifugal force, impurities attached to the inner wall of a primary filter screen cover are promoted to be thrown away; meanwhile, the movable sealing ring can stretch the elastic connecting rope in the centrifugal process, so that a gap is formed between the movable sealing ring and the filter cartridge, impurities attached to the outer wall of the fine filter screen cover are thrown out through the gap, and the function of cleaning the fine filter screen cover and the primary filter screen cover is achieved.

Description

technical field [0001] The invention relates to a water discharge device, relates to the technical field of auxiliary devices for petroleum exploitation, and in particular to a formation water discharge device for petroleum exploitation. Background technique [0002] Oil extraction refers to the act of excavating and extracting oil in the place where oil is stored. During the process of oil extraction, formation water will seep into the interior of the oil mine. In order to prevent floods in the oil mine, drainage equipment must be used to clean the mine. The formation water is discharged. There are following problems at prior art: [0003] 1. The existing drainage device does not have the function of automatically cleaning the filter screen, and the filter screen will be blocked after a period of use, which will affect the normal operation of the drainage device; [0004] 2. The existing drainage device does not have the function of lifting the soil, and the inside of the...
