Description
Technical Field
The invention belongs to the technical field of engineering equipment, and particularly relates to a wellhead device for oilfield operation.
Background
When equipment needs to be moved away from a well mouth in the well repairing process by using the small well repairing mouth automatic operation device, the equipment can be generally hoisted by using a crane. When the equipment needs to be moved to the wellhead, the crane is reused. The arrangement of the crane is complicated, and the additional cost is generated, so that inconvenience is brought to well repair. Patent CN207296890U discloses a fixing device for avoiding a wellhead, which comprises two vertically-arranged brackets, a horizontal pull rod is arranged at the lower part between the two brackets and detachably connected with the two brackets, a second positioning protrusion is arranged on the pull rod, two inclined support rods are provided, catwalk table tops are arranged on the tops of the two brackets, a first set of positioning protrusions are arranged on the catwalk table tops, when an inlet is avoided, the other ends of the two inclined support rods are detached from the pull rod, the other ends of the inclined support rods are connected with the first set of positioning protrusions, and the pull rod is detached from the brackets, so that the wellhead is effectively avoided and a stable fixing device is formed; CN207513573U relates to blowout preventer transfer device among the oil drilling technical field, blowout preventer transfer device includes the walking frame, the top of walking frame is equipped with the load-bearing platform that supplies the blowout preventer to place, the bottom of walking frame is equipped with the walking wheel, the below of load-bearing platform has the dodge space that is used for keeping away the well drilling wellhead department and stretches out the piece, lay the track that supplies blowout preventer transfer device to walk on the derrick base before using, install blowout preventer transfer device on the track, install the blowout preventer on load-bearing platform, leave the dodge space that is used for dodging supply wellhead department to stretch out the piece between load-bearing platform and the track, transfer device can transfer the blowout preventer to well drilling department directly over, after lifting the blowout preventer, need not readjust the horizontal position of blowout preventer. Wherein, CN207296890U only raises the position of drilling equipment simply, can't solve above-mentioned technical problem completely, and CN207513573U needs equipment such as additional design support frame, walking wheel, hydraulic motor, and the feasibility of implementation is relatively poor.
