Description

Technical Field

[0001] This application relates to the field of oilfield production, and in particular to an electric lubrication and maintenance device for the wire of a well test winch. Background Technology

[0002] Wireline well testing involves using a well-testing winch to raise and lower instruments and tools connected to a wireline on a drum. However, after the wireline is pulled out of the well, it corrodes, leading to oil, gas, and water leaks and preventing the tool string from descending. Therefore, safe and effective lubrication and maintenance of the wireline are necessary during the winch's raising and lowering process.

[0003] The traditional method involves manually applying machine oil to the wire rope drum using a brush. However, since the winch drum rotates during the hoisting and lowering process, directly applying oil poses significant safety hazards. Furthermore, stopping the winch rotation before applying oil during wire rope testing results in low testing efficiency, unlubricated areas, and the inability to arbitrarily stop hoisting and lowering for many tests. Manual oiling also leads to problems such as oil accumulation under the drum, difficult cleaning, oil splashing onto the observation window during drum rotation obstructing the operator's view, uneven wire rope lubrication, and wasted oil.

[0004] Therefore, based on the requirements of safety and quality target assessment, it is necessary to develop a wire lubrication and maintenance device for well testing winches to ensure wire lubrication while also protecting the safety of construction personnel. Utility Model Content

[0029] Example:

[0030] Please refer to Figure 1 (Refer to) Figure 2This application provides an electric lubrication and maintenance device for the wire rope of a well test winch. It is mainly used to lubricate and maintain the wire rope 6 on the drum of the high-speed rotating well test winch 5 during the raising and lowering process. It mainly includes a spray assembly, a pressure regulating valve 1, an air inlet pipe 2, an oil storage tank 3, and an oil delivery assembly. The spray assembly includes a galvanized spray pipe 11. The pressure regulating valve 1 is installed on the upper outer side of the well test winch 5 and is used to regulate the pressure of the gas entering the oil storage tank 3. One end of the air inlet pipe 2 is connected to the pressure regulating valve 1, and the other end is connected to the top air inlet of the oil storage tank 3, used to deliver gas into the oil storage tank 3 so that the lubricating oil in the oil storage tank 3 can enter the oil delivery assembly. The oil delivery assembly includes an oil outlet pipe 7, a solenoid valve 8, an oil spray pipe 9, and an electric... Switch 10, one end of oil outlet pipe 7 is connected to the bottom outlet of oil storage tank 3, and the other end is connected to solenoid valve 8; solenoid valve 8 is installed on the lower outer side of well test winch 5, and electric switch 10 is electrically connected to solenoid valve 8 to control the opening and closing of solenoid valve 8; one end of oil spray pipe 9 is connected to solenoid valve 8, and the other end is connected to galvanized spray pipe 11 to deliver lubricating oil to multiple atomizing nozzles 4 on galvanized spray pipe 11; galvanized spray pipe 11 is horizontally arranged directly above drum wire 6, and one end is connected to oil spray pipe 9; multiple atomizing nozzles 4 are respectively connected to the bottom of galvanized spray pipe 11 at intervals, and are respectively arranged above drum wire 6 of well test winch 5 to atomize lubricating oil and spray it onto the surface of drum wire 6.

[0031] This device enables operators to lubricate and maintain the wire 6 on the well test winch 5 drum without contacting the rotating winch drum during normal raising and lowering. It can conveniently and quickly lubricate the wire 6 through components such as solenoid valve 8 and electric switch 10, thereby reducing the labor intensity of workers, improving construction efficiency, and ultimately achieving safe and effective lubrication and maintenance operations.

[0032] It should be noted that in this embodiment, the galvanized nozzle 11 can be a DN15 galvanized steel pipe; and three atomizing nozzles 4 can be used, with the same spacing between adjacent atomizing nozzles 4. In other embodiments, the number of atomizing nozzles 4 can be four, five, etc., and is not limited to the number and design form in this embodiment.

[0033] Furthermore, this device utilizes the existing pneumatic and electrical systems of the well testing vehicle, with the vehicle's engine air pump providing the air source and the vehicle's battery providing the power, saving on equipment investment. The gas, regulated by the pressure regulating valve 1, is delivered to the oil storage tank 3 via the air inlet pipe 2. This allows the lubricating oil in the oil storage tank 3 to flow into the inlet of the solenoid valve 8 via the oil outlet pipe 7. The electric switch 10 controls the opening and closing of the solenoid valve 8, delivering the lubricating oil via the spray pipe 9 to the atomizing nozzle 4 on the galvanized spray pipe 11 for atomization. Finally, the atomizing nozzle 4 sprays the lubricating oil onto the surface of the winch drum wire 6, achieving lubrication of the winch drum wire 6. This achieves safe and effective lubrication and maintenance without contact with the rotating drum.

[0034] It should be noted that the electric switch 10, solenoid valve 8, pressure regulating valve 1, and atomizing nozzle 4 all adopt existing technological structures, and their specific structures and working principles will not be elaborated here. Therefore, the use of electric switches 10 and solenoid valve 8 for control is convenient; operators only need to operate according to the buttons, ensuring safety and reliability, and reducing the labor intensity of operators. Simultaneously, the pneumatic atomizing spray design allows for adjustment of the air supply pressure and the size of the atomizing nozzle 4 to control the oil spray volume, making operation convenient, safe, and reliable. It also reduces the labor intensity of operators, allowing them to perform safe and effective lubrication maintenance without contacting rotating parts, ensuring operator safety and providing good lubrication of the wire 6 on the well test winch 5, while being environmentally friendly. Furthermore, the oil storage tank 3 and pressure regulating valve 1 ensure that the air pressure used does not exceed the specified requirements, achieving the purpose of safe operation. The galvanized nozzle 11 and atomizing nozzle 4 ensure that the sprayed lubricating oil evenly covers the surface of the drum wire 6, guaranteeing the lubrication coverage of the wire 6 on the well test winch 5.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
