Abstract

The invention relates to an automatic running and pulling system of an oilfield workover string, which comprises a blowout preventer, fixing slips, an oil pipe/sucker rod guide mechanism, an oil pipe/sucker rod locating mechanism, an oil pipe/sucker rod elevator component, a mechanical arm component, hydraulic clamps, a hydraulic clamps bracket, a control system, a base component and a string bent, wherein the mechanical arm component and the hydraulic clamps bracket are installed on the base component and are connected through a linkage component to carry out linkage movement, and the string bent is arranged on the side surface of the mechanical arm component and moves in match with the mechanical arm component. With the adoption of the automatic running and pulling system of the oilfield workover string, the automation of movements of snatching up, butt joint, clamping, upper unloading, elevating, lowering, arrangement and the like can be realized, manual string running and pulling operation at a wellhead is replaced, an equipment mechanism is simplified as much as possible, and an operation program is optimized.

Description

technical field [0001] The invention relates to the field of oil field workover operation equipment, in particular to an automatic lifting system for an oil field workover pipe string. Background technique [0002] Oilfield workover operations are mainly to ensure the normal production of oil wells or to overhaul, maintain and adjust oil wells according to production needs. It is an important production link to ensure stable and high production in oil fields. One of the very heavy tasks is lifting and lowering oil pipes, sucker rods and downhole tools. [0003] Over the years, my country's oilfield workover has been using the traditional operation method, using crescent elevators to realize the lifting and lowering operation of the pipe string. It is basically a manual operation, requiring manual switching of oil pipes or sucker rod elevators, lifting rings, pushing and pulling hydraulic pliers, pushing and releasing small blocks, and auxiliary oil pipe positioning. The pro...
