Description

Technical Field

[0001] The utility model relates to the technical field of sewage floating oil recovery equipment, in particular to an oil well workover sewage floating oil recovery device. Background Technique

[0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons with natural occurrence. Petroleum is further divided into forms such as crude oil, natural gas, natural gas liquids and natural tar, but conventionally, "petroleum" is still used as the definition of "crude oil". When working over oil wells, the sewage produced contains floating petroleum, which needs to be recovered.

[0003] For example, an oil well workover sewage floating oil recovery device with the authorization announcement number of "CN219991239U" solves the problem that the existing device sucks floating oil through a floating suction device. However, the floating suction device sucks oil at a fixed point, not only with low efficiency of sucking floating oil, but also a large amount of sewage will be sucked in the sucking process, resulting in a large workload for subsequent oil-water separation. However, for this oil well workover sewage floating oil recovery device, the height of the suction head is driven by a hydraulic cylinder to move. When the amount of sewage in the sewage tank is small, the moving range of the hydraulic cylinder is small, and the sewage at the bottom of the sewage tank cannot be sucked, which increases the working limitation of the floating oil recovery device. At the same time, for this oil well workover sewage floating oil recovery device, when sucking sewage, since the sewage contains some impurities such as solid floating objects, these impurities will block the suction head, resulting in a slower speed of sucking floating oil by the suction head, which reduces the working efficiency of the floating oil recovery device.
