Description
Technical field
The present invention relates to the derrick field of oil and gas industry well workover, especially a kind of hydraulic stretches well
Frame.
Background technique
Currently, oil and gas industry workover rig mainly uses self-propelled truck mounted well servicing unit.However in China Sichuan oil
The oil/gas well multidigit on the ground such as field, Changqing oilfields is in mountain area, hilly country, and oily area's road transport condition is poor, and conventional is self-propelled
Truck mounted well servicing unit leads to the work that its passage capacity is bad, can not adapt to such area because of the reasons such as cross-country power, turning radius
Industry environment.
According to investigation and analysis, to solve this problem, the mainstream solution taken is as follows in oily area: using a kind of passability
Fabulous crawler-type pigging machine substitutes the winch of conventional workover rig, cooperates a kind of free-standing two sections pin joint or bolted derrick, should
Derrick head room 29m, two section foldings are hauled with platform trailer when transport, and when operation first uses crane to assist will upper and lower two section company
It is connected together, is then lifted to a kind of dedicated derrick and stands up on the bracket of vehicle, stand up the lift oil tank on vehicle by derrick and push
Bracket derrick telescoping in place, then accomplishes fluently guy wire, and derrick stands up after vehicle withdraws bracket and voluntarily sails out of, crawler-type pigging machine in place into
Row workover treatment.Such as the big operating space telescope pole recorded in Chinese patent literature CN2769489Y.
Main problem existing for the solution is as follows:
1, the derrick transportation lengths of free-standing two section pin joints or bolt are larger.A height of 29 meters of headroom of two section pin joints or bolt well
Frame, the folded total length of two section of travel position are about 15 meters, and turning radius requires high；
2, the process being attached upper and lower two sections derrick is time-consuming, laborious and safety is bad, raising operating difficulties；
3, derrick lifts to derrick to the process for standing up trolley bracket is time-consuming, laborious and safety is bad；
4, it is with high costs to stand up vehicle for the derrick being equipped with.Conventional derrick stands up car owner will be by second-class chassis, hydraulic oil container, preceding branch
The compositions such as support, rear support, derrick bracket, lift oil tank, locking cylinder, adjusting oil cylinder, cost is costly.
