Description

Technical Field

[0001] The invention relates to the technical field of oil and gas exploitation, in particular to a tower-type oil pumping unit operation yielding device. Background Art

[0002] The tower pumping unit is a mechanical oil production equipment. Compared with the walking beam pumping unit, it has a longer stroke, which meets the demand of long-stroke slow-sprint mechanical production. The tower pumping unit has become the mainstream configuration of many well sites due to its stable structure, large lifting height, and strong adaptability. However, during daily operation and maintenance or downhole tool operations (such as logging, salvage operations, well repair, etc.), it is often necessary to temporarily vacate the area above the wellhead so that maintenance equipment and operating tools can smoothly enter the well for operation. This requires the pumping unit originally fixed directly above the wellhead to be given way. At present, there are two main ways of making way on site: one is to lift the entire pumping unit away from the wellhead area by a crane, and the other is to manually push the pumping unit after disassembling part of the structure. However, both methods have obvious defects. The lifting operation has high requirements for the site, and large lifting equipment needs to be additionally deployed, which increases transportation costs, and there are major safety hazards in high-altitude operations; the disassembly method is labor-intensive, requires the cooperation of multiple people, is inefficient, and frequent disassembly and assembly can easily cause equipment component wear and affect its service life; it is inconvenient to operate under severe weather conditions such as wind, sand, rain, snow or mud, and there are problems such as long wellhead exposure time and high pollution risk; most current devices lack auxiliary support structures and wellhead shielding functions. During the making way process, there are risks of structural instability such as displacement, tilting, or even collapse of the center of gravity of the pumping unit. At the same time, the wellhead is easily invaded by debris or safety hazards due to exposure. Therefore, the present application discloses a tower-type pumping unit operation making way device to meet the demand for a device that can quickly make way without disassembling the main body of the pumping unit.
