Example Embodiment

[0011] External working process: The device can be separated from top to bottom, the top and bottom are connected by a conical fitting structure, and the bottom is connected to Figure 4 The main drain device. The main oil drain device is connected to the wellhead. First, pass the oil pumping wire rope through the upper part of the device, and then install the oil sucker. The upper part of the device is stuck on the oil sucker. When it is necessary to replace the oil sucker When the plunger is used, the upper part of the device rises with the wire rope. The test oil production starts to transport the steel wire rope downhole to the designated position. When the steel wire rope is lifted up, the device starts to send air to clean up the oil stains on the wire rope from the downhole belt.

[0012] The working principle of this device: using compressed air as a cleaning medium, let the air flow enter the air inlet pipe of the device through the high-pressure air pipe, and blow off th...

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...
