Rotational flowcleaner

Abstract

The invention relates to the technical field of oil casing washing, in particular to a rotational flowcleaner. The rotational flowcleaner comprises a turbine motor, a drive shaft assembly and a sprayer, the lower end of the turbine motor is connected to the drive shaft assembly, and the lower end of the drive shaft assembly is connected to the sprayer; the turbine motor comprises an upper contact, the outer wall of the lower portion of the upper contact is connected to an outer canister, the lower end of the outer canister is connected to a lower contact of the outer canister, the lower end of the lower contact of the outer canister is connected to the drive shaft assembly, the outer canister is internally provided with a core shaft, the upper end of the core shaft is provided with a stream guidance cone, a bearing bush is arranged between the core shaft and the outer canister, the lower portion of the bearing bush is provided with a guide wheel, the upper and lower ends of the guide wheel are connected to the bearing bush and the lower contact of the outer canister in an inserting mode respectively, the outer wall of the core shaft is sleeved with a turbine, the lower portion of the core shaft is provided with a flushing port, the flushing port is located at the lower portion of the turbine, and the lower end of the core shaft is connected to the drive shaft assembly through a lower contact of the core shaft. The rotational flowcleaner is simple in structure, during oil casing washing, an oil outlet pipe does not need lifting, the labor intensity is low, the required time is short, the cleaning speed is high, the cleaning effect is good, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of oil casing cleaning, in particular to a cyclone descaler. Background technique [0002] Scaling is unavoidable in the oil and gas production process of oil wells, and the insoluble mixture is gradually mixed together and adhered to the drilling equipment and pipelines, making the surface of the production tubing rough, increasing the frictional resistance, reducing the flow rate, and even reducing the flow cross-sectional area of ​​the tubing. become smaller, so that the production efficiency is greatly reduced. There are two commonly used descaling methods at present, chemical descaling and mechanical descaling. Chemical descaling will cause damage to downhole tubing and tools, and the cost is high; while mechanical descaling requires single-well operation to pull out the tubing, which affects water injection operations, and is time-consuming, labor-intensive, and costly.
