Description

Technical Field

[0001] The utility model relates to the technical field of petroleum exploitation, and more particularly to an oil-water separation device for petroleum exploitation. Background Art

[0002] Oil-water separation is a crucial step in the oil extraction process. Since underground oil layers often contain water, when oil is extracted to the ground, crude oil usually mixes with groundwater (i.e., produced fluid). Therefore, an effective oil-water separation device is needed to separate the two for further processing and utilization.

[0003] When extracting the separated oil, the oil suction pipe needs to be inserted into the oil layer of the separation box, but the height of the oil suction port of the oil suction pipe is not convenient to adjust, and it is not convenient for the device to keep the oil suction port of the oil suction pipe in the separated oil layer during the extraction process, which is inconvenient to use. During the oil extraction process, there will be some mud and sand in the oil-water mixture. After separation, the mud and sand will settle at the bottom of the separation box. During the drainage process of the drain outlet, the mud and sand will be discharged, affecting the effect of oil-water separation. However, when filtering the mud and sand, the existing separation device is not convenient for disassembling and cleaning the filter screen, resulting in mud and sand accumulation on the filter screen, affecting the filtration efficiency, and further affecting the oil-water separation efficiency.
