The present disclosure provides an automatic minor repair operation system for an oil field, a pipe column conveying and discharging device for use in an automatic minor repair operation apparatus system, an anti-opening mechanism for an elevator and a turnover elevator, a manipulator and a workover operation device for a workover operation, an integrated automatic wellhead operation apparatus, and a power slip for an oil field workover operation. The automatic minor repair operation apparatus system includes: a workover machine, a pipe column conveying and discharging device, an elevator for a workover operation, a manipulator for a workover operation, an integrated automatic wellhead operation apparatus, and a power slip for an oil field workover operation. The workover machine is arranged along a first direction of the automatic minor repair operation apparatus system, such that a longitudinal direction of the workover machine is parallel to the first direction, and a tail of the workover machine is arranged to be spaced a predetermined distance from a wellhead center in the first direction, where the first direction is a direction passing through the wellhead center along a radial direction of the wellhead. The pipe column conveying and discharging device is arranged on a first side of a second direction of the automatic minor repair operation apparatus system, where the second direction is a direction passing through the wellhead center and perpendicular to the first direction. The elevator for a workover operation, the manipulator for a workover operation, and the integrated automatic wellhead operation apparatus are arranged on the tail of the workover machine, are carried by the workover machine, and are arranged on a second side that is of the second direction of the automatic minor repair operation apparatus system and that is opposite to the first side. The power slip for an oil field workover operation is arranged at the wellhead center, and is configured to switch between an open position where a pipe column is allowed to move through and a closed position where the pipe column is prevented from moving through. According to the automatic minor repair operation apparatus system of the present disclosure, the on-site practicability and the working efficiency of the oil field operation are remarkably improved, the unmanned wellhead operation is achieved, the labor intensity of workers is greatly reduced, the working environment is improved, and the safety factor is improved; and meanwhile, the wellhead center can be accurately positioned.

Automatic small repair operation system for oil field

The present disclosure provides automated equipment for drilling and workover operations of oil field, and an oil field workover operation device, an integrated hydraulic clamp, a buckling apparatus and a string automated operating apparatus, and a derrick floor pipe handling manipulator for use in the automated equipment. The automated equipment comprises a workover rig, a derrick floor, an elevator, a monkey-board string automatic placement apparatus, a slip, an oil field workover operation device, a power clamp, and a derrick floor pipe handling manipulator, and the workover rig, the derrick floor, the elevator, the monkey-board string automatic placement apparatus, the slip, the oil field workover operation device, the power clamp, and the derrick floor pipe handling manipulator cooperate with each other to realize a lifting operation and a lowering operation of a string at a wellhead. The workover rig has a derrick, the workover rig is arranged along a front-rear direction of the automated equipment, and the derrick is disposed at a rear end portion of the workover rig and aligned with the wellhead. The derrick floor is placed on the ground and disposed at the wellhead, and the derrick floor is disposed adjacent to the derrick. The oil field workover operation device is positioned on one side of the wellhead in a left-right direction of the automated equipment, and the oil field workover operation device is disposed on the derrick floor in a manner of being movable between a raised position where the oil field workover operation device extends out above the derrick floor and a retreated position where the oil field workover operation device retreats below the derrick floor. The automated equipment in the present disclosure significantly improves operation efficiency of the drilling and workover operations, greatly reduces manual operation strength, and improves safety factor.
