Advantage of the present utility model: the labour intensity that 1, has alleviated the driller personnel.2, avoid causing in the well workover process equipment and fatal accident.3, service machine scientific and technological content and automatization level have been improved.4, realized remote monitor and control to remedial work field operation parameter.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model control module block diagram.
The specific embodiment
Referring to Fig. 1, the service machine remote intelligent control system comprises plc, and plc is connected with brake control unit, drum clutch control unit, diesel engine oil door control unit, cylinder absolute value encoder, hook block load pressure transmitter and well head feedback signal unit.
Control principle:
Well pulling job: after finishing the well pulling job preparation, control system switches to the Based Intelligent Control state, the TTC60 programming controller (is used U.S. import SM4 series solenoid-operated proportional servo operated valve to the brake control unit, working clamp hydraulic actuating cylinder and the safety tongs hydraulic actuating cylinder of control brake system), the drum clutch control unit (is used MFH-3-1/2-TT40-SA electromagnetic control air valve, the compressed-air actuated supply of index drum power-transfer clutch or stop to supply with) and the diesel engine oil door control unit (itself carries diesel engine, carry out data transmission by the CAN bus that connects with TTC60) send action command, drum clutch engages brake system releasing of brake simultaneously, diesel engine throttle strengthens engine speed to be increased, and carries flow column on hook block is quick; Be installed in the signal that the RSA698 multi-turn absolute value encoder on the cylinder is gathered, after the programming controller computing, feed back speed and the relative position of hook block in real time, the oil pipe that proposes when hook block is during near the length of an oil pipe, programming controller sends instruction to the diesel engine oil door control unit, reduce diesel engine speed, when the flow column length that proposes is the length 500mm of manying than an oil pipe, programming controller sends action command to brake control unit and cylinder clutch unit, check brake and loosen the clutch, hook block hovers over relative position; The well head operating personal is fastened on pipe elevator on the oil pipe below the tubing string tubing collar, then manually to the programming controller output feedback signal, after programming controller is received the well head feedback signal, send action command to the brake control unit, slowly discharge brake, hook block is slowly transferred, and makes tubing string pass through the string collar seat on the well head elevator; By the weight on hook feedback signal, after the judgement hook does not bear tubing string weight, finish intelligent control program.Well head operating personal operation hydraulic tubing tong is realized the oil pipe shackle, after shackle was finished, driller's manual control hook block cooperated with the well head operating personal, and the oil pipe that proposes is guided on the pipe framed bent of well site, manually take suspension ring and elevator from the oil pipe that has unloaded, and suspension ring are hung on the well head elevator.Open intelligence control system, carry out putting forward program on next root oil pipe.
Following oil pipe operation: the driller cooperates with the well head operating personal, the index drum brake, transferring hook block manually hangs over suspension ring on the pipe elevator of managing on the framed bent, releasing of brake engages drum clutch simultaneously, the control diesel engine throttle, make hook block mention oil pipe with suitable speed, manually set upright oil pipe, make the oil pipe pin thread of carrying on hook block, align the box that is suspended on the OIH string collar by pipe elevator, slowly transfer hook block, the oil pipe pin thread is docked with the box cupling box, stop and tightly brake, well head operating personal process oil pipe wrench is realized buckleing on the oil pipe, after hydraulic tubing tong is finished button and playback, carry flow column 500mm in driller's manual operation and hover, the well head operating personal shifts out elevator from wellhead flange, then manually to the programming controller output feedback signal, after programming controller is received the well head feedback signal, oil drain tube task program under the beginning Based Intelligent Control: programming controller sends instruction to the brake control unit, releasing of brake, transfer tubing string, be installed in the signal that the multi-turn absolute value encoder on the cylinder is gathered, after the programming controller computing, feed back speed and the relative position of hook block in real time, according to the location parameter of hook block, when judging elevator near well head, programming controller sends action and parameter instruction to brake units, and the slow seat of the elevator on the control tubing string is on well head, by the weight on hook feedback signal, after judging that hook does not bear tubing string weight, finish Based Intelligent Control and transfer program.
