Description
Technical Field
The utility model relates to an oil field well workover area presses operation technical field, concretely relates to hydraulic control oil pipe coupling detection device and oil pipe coupling detection method thereof.
Background
In the process of using the under-pressure operation device to carry out workover operation on an oil field to pull out and pull down an oil pipe, the relative position of a tubing coupling in the under-pressure operation device needs to be determined, namely when the tubing coupling is positioned between an upper half blowout preventer and a lower half blowout preventer, the upper half blowout preventer and the lower half blowout preventer are respectively closed and opened to lead out the coupling.
At present, oil pipe coupling detectors (devices) are various, electrically controlled, pneumatically controlled and ultrasonic, but the use effect is not ideal. The detection method mainly has two types: firstly, use the oil pipe detection instrument, install the oil pipe detection instrument between two half blowout preventers promptly, when the tubing coupling passes through, send a signal, operating personnel according to signal indication, operate closing, opening of two half blowout preventers respectively, derive the coupling. Secondly, a measurement and observation method is adopted, the distance between the middle point between the two half blowout preventers and the operation platform is measured in advance, then the difference of the distance is subtracted according to the standard length of the oil pipe, an identifier is made on the derrick above the platform, the distance between the identifier and the middle point between the two half blowout preventers is equal to the standard length of the oil pipe, then the derrick cross-bracing position of the hook (or the elevator) relative to the derrick height direction is determined according to the identifier, and in the operation process, the relative position of the oil pipe coupling between the two half blowout preventers in the pressurized operation device is judged by observing the derrick cross-bracing position of the hook (or the elevator) relative to the derrick height direction visually.
The method for determining the relative position of the tubing coupling in the pressurized operation device by using the tubing detector is advanced, but the well repairing site environment condition is poor, the electrical appliance element fault is easily caused, the condition in the well is complex, the signal output by the tubing detector is easily misreported or missed due to the reasons of tubing scaling, deformation and the like, the accuracy rate of signal output cannot be ensured to be 100%, and the equipment fault is easily caused because the tubing coupling is hung and damaged by a half-sealing flashboard.
Currently, a measurement and observation method is commonly used in a device operating under pressure, namely, pre-measurement and visual observation are used for determining the relative position of a tubing coupling in the device operating under pressure. Firstly, if the operation platform is arranged on the operation platform, the operator can conveniently observe the wellhead, but when the operator observes the position of the hook (or elevator) relative to the cross arm of the derrick in the height direction, the operator needs to be careful, the posture is tired, and the operation platform is not accurate. Secondly, if the operation platform is arranged in front of the container type hydraulic station and is about 20 meters away from the operation position of the wellhead, an operator can easily observe the position of the big hook (or the elevator) relative to the cross arm of the derrick in the height direction, but the observation of the wellhead is inconvenient, the working situation on the platform is difficult to see, as the field noise is large, the language communication is difficult, the communication can only be realized by gestures, the action of the operator of the workover rig is difficult to coordinate, serious safety accidents are easy to cause, and the operation efficiency is low.
In the detection method, the inner diameter of the axial channel of the under-pressure operation device needs to be ensured to pass through the oil pipe hanger, and the outer diameter of the oil pipe is much smaller than the outer diameter of the oil pipe hanger, so that the clearance between the oil pipe and the axial channel of the under-pressure operation device is larger, and the oil pipe is easy to deviate from the center of the axial channel of the under-pressure operation device in the lifting process, so that the collar on the oil pipe is not detected accurately and reliably.
