Device for sealing and cleaning cable wires at well head

Abstract

The invention provides a device used for testing oil extraction in an oil field, which is arranged at a well head and hermetically cleans the sucking cable wires. The device consists of three pipelines: an air inlet pipeline, a main pipeline and an air outlet pipeline; the air inlet pipeline and the air outlet pipeline are connected with two sides of the main pipeline respectively; the device can be divided into an upper part and a lower part that are connected with each other by a conical matching structure; wherein the lower part is connected with a main oil discharging device which is connected with the well head; firstly, the sucking cable wire passes through the upper half part of the device; subsequently, other parts used for sucking oil from a sucking well are installed. The device takes the compressed air generated by the air compressor as the cleaning medium, leads the airflow to enter the air inlet pipeline of the device by a high-pressure air pipe, blows out the oil dirt of the sucking cable wire passing through the center of the whole device by the circular gun nozzle of the main pipeline, and the airflow drives the oil dirt to be discharged out through the air outlet pipeline of the device, thus completing the whole process.

Description

technical field [0001] The invention of the present application relates to the auxiliary equipment of mechanical equipment in the petroleum industry. It is a device installed at the wellhead to seal and clean the oil pumping wire rope during the test production of oil wells in oil fields. Background technique [0002] In the current technology, the devices used to seal and clean the oil pumping wire rope on oil wells mostly use packing type, allowing the packing to pass through and rub against the wire rope to achieve the purpose of cleaning. Disadvantages: The packing is easy to wear and needs to be replaced frequently during work, and it is easy to leak during the second or third reciprocating process during oil pumping, causing pollution to the surrounding environment; it is not conducive to environmental protection. The cleaning effect on the wire rope is not ideal. Contents of the invention [0003] The invention of the present application provides a device, which ha...
