Embodiment Construction

[0016] see figure 1 , The remote intelligent control system of the workover rig includes a programmable program controller, a programmable program controller and a brake control unit, a drum clutch control unit, a diesel engine throttle control unit, a drum absolute value encoder, and a traveling block hook load pressure transmitter And wellhead feedback signal unit connection.

[0017] Control principle:

[0018] Oil pipe lifting operation: After the oil pipe lifting operation preparation is completed, the control system switches to the intelligent control state, and the TTC60 program controller sends the brake control unit (using the SM4 series electromagnetic proportional servo control valve imported from the United States to control the working tong hydraulic cylinder and safety gear of the braking system) hydraulic cylinder), roller clutch control unit (using MFH-3-1 / 2-TT40-SA electromagnetic control air valve to control the supply or stop of the compressed air supply of...

Abstract

The invention relates to a remote intelligent control system for a workover rig, i.e. intelligent operation of the workover rig can be realized through a remote intelligent control program. The system employs a programmable controller, which is in connection with a brake control unit, a roller clutch control unit, a diesel engine throttle control unit, a roller absolute value encoder, a travelling block hook load pressure transmitter and a wellhead feedback signal unit. With the system provided in the invention, the labor intensity of drillers is mitigated, equipment and personal accidents can be avoided during well repairing, the technology content and automation level of the workover rig can be improved, and remote monitoring on field operation parameters of workover operation is realized.

Description

technical field [0001] The invention relates to a remote intelligent control system of a petroleum workover rig, that is, the intelligent operation of the workover rig is realized through a remote intelligent control program. Background technique [0002] In the prior art, the operation process of lifting and lowering the tubing by the workover rig all needs to be operated manually. Tubing operation: the driller needs to release the drum brake first, engage the drum clutch and increase the throttle of the diesel engine at the same time, so that the drum is wound with a steel wire rope and the tubing string is quickly lifted through the swimming system composed of the derrick crown block and the traveling block hook. When the proposed oil pipe is close to the length of one oil pipe, reduce the throttle of the diesel engine to slow down the lifting speed of the oil pipe string; when the coupling of the oil pipe string is lifted out of the wellhead, brake the roller brake and d...
