One, technical field
The present invention relates to blowout kill-job control system in geological prospecting, oil drilling, the underground work process, particularly a kind of blowout kill-job automaton.
Two, background technology
When controlling blowout in traditional drilling well, the operation, the control mode of well head pressure is mainly leaned on the variation of manual observation standpipe and casing pressure, in view of the above with manually or utilize the pneumatic adjusting rotary valve and the choke valve that surges, to change the pressure size of standpipe and cover, to reach the purpose of control blowout.But this control mode exists following shortcoming or deficiency: the 1. size of manual observation pressure, and data error is big, and pressure control is inaccurate; 2. the Artificial Control throttle speed is slow, and operation lags behind, and incompatible continuous, accurately control to bottom pressure often cause kill-job unsuccessful; 3. wellhead manifold pressure is up to tens0 Mpa, and there is potential safety hazard in manually-operated; 4. the shaft bottom is returned in the fast thing and is had hydrogen sulfide, and pernicious gases such as carbon monoxide are harmful to health of human body.
Three, summary of the invention
The purpose of this invention is to provide a kind of blowout kill-job automaton, adopt computer controlled automatic, improve control accuracy, guarantee personal safety, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Blowout kill-job automaton of the present invention, comprise pressure sensor, flow transmitter, data acquisition and treatment system, Industrial Personal Computer (IPC), hydraulic control servo-control system, hydraulic control choke valve, manual control system, in real time/historical operating mode demonstration, sound and light alarm, printer, density instrument and be installed on hydraulic control choke valve on the choke manifold.Described Industrial Personal Computer (IPC) is connected with pressure sensor, flow transmitter with data Collection ﹠ Processing System in turn, be connected in turn with the hydraulic control choke valve with the hydraulic control servo-control system, also respectively with the density instrument, in real time/historical operating mode demonstration, sound and light alarm, printer be connected, pressure sensor and flow transmitter are installed on the standpipe, and above-mentioned each unit is controlled by Industrial Personal Computer (IPC) automatically.
Wherein, be installed in parallel manual control system on the described hydraulic control choke valve.Described data acquisition and treatment system comprise interconnective A/D converter and PCL card.The remote monitoring mouth is installed on the described Industrial Personal Computer (IPC).
The present invention has following advantage compared with prior art:
1, adopt computer controlled automatic, pressure control accurately, in time;
2, can store, consult history and instant data, easy to operate;
3, guarantee personal safety;
4, have printing, sound and light alarm and remote control function, safe and reliable.
5, because choke manifold pilot operated valve device opening degree influences the variation of standpipe pressure again, by Industrial Personal Computer (IPC) to adopt standpipe pressure and injection rate, with the data contrast of calculating before the kill-job, adjust in real time, thereby realize the closed-loop control of blowout kill-job;
6, can carry out remote monitoring by remote monitoring mouth 8.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the embodiment of the invention
Five, the specific embodiment
Consult accompanying drawing, a kind of described blowout kill-job automaton, comprise flow transmitter 1, pressure sensor 2, data acquisition and treatment system 3, Industrial Personal Computer (IPC) 4, hydraulic control servo-control system 5, hydraulic control choke valve 6, manual control system 7, in real time/historical operating mode shows 11, sound and light alarm 10, printer 9, density instrument 12 and be installed on hydraulic control choke valve 6 on the choke manifold.Industrial Personal Computer (IPC) 4 is connected with pressure sensor 2, flow transmitter 1 with data Collection ﹠ Processing System 3 in turn, be connected in turn with hydraulic control choke valve 6 with hydraulic control servo-control system 5, also respectively with density instrument 12, in real time/historical operating mode shows 11, sound and light alarm 10, printer 9 are connected.Pressure sensor 2 and flow transmitter 1 are installed on the standpipe, and above-mentioned each unit is controlled by Industrial Personal Computer (IPC) 4 automatically.
Be installed in parallel manual control system 7 on the hydraulic control choke valve 6.Data acquisition and treatment system 3 comprise interconnective A/D converter and PCL card.Remote monitoring mouth 8 is installed on the Industrial Personal Computer (IPC) 4.
During operation, blowout kill-job process neutral tube pressure and flow are passed the signal along to collection and treatment system 3 by pressure sensor 2 and flow transmitter 1, data input Industrial Personal Computer (IPC) 4 after collection and treatment system 3 processing, Industrial Personal Computer (IPC) 4 is controlled the servo-control system 5 of surging, the opening degree of hydraulic control servo-control system 5 control hydraulic control choke valves 6, the size of regulating standpipe and casing pressure in real time, Industrial Personal Computer (IPC) 4 control density instrument 12, in time measure the size of well killing fluid density, timely adjustment density.Choke manifold pilot operated valve device 6 opening degrees influence the variation of standpipe pressure again.Adopt to such an extent that the data calculated before standpipe pressure and injection rate and the kill-job compare by 4 pairs of Industrial Personal Computer (IPC)s, adjust in real time, thereby realize the closed-loop control of blowout kill-job.Can carry out remote monitoring by remote monitoring mouth 8.
