Description
Technical field
The utility model relates to a kind of drilling well monitor controller, the real-time monitor controller of particularly a kind of under balance pressure drilling.
Background technology
Formation fluid will controlledly flow into pit shaft in the under balance pressure drilling process, and well kick or blowout promptly controlledly take place.But because the complexity and the unpredictability of reservoir situation often run into some fortuitous events during drilling well, if can not in time find and handle these problems, the effect of under balance pressure drilling will be subjected to very big influence, even can bring out uncontrollable overflow.For guaranteeing in whole drilling process, all to keep desirable under-balanced state, must monitor in real time and control drilling condition.Under balance pressure drilling need be equipped with independently Hydraulic Station in addition, and system provides hydraulic power source and lubrication oil for the rotation blowout prevention.
Generally do not have the drilling well monitor controller in the under balance pressure drilling process at present, drilling crew mostly adopts mechanical type instrument and indicator, and by manually watching, collect data, the objective sum of errors subjective error of data record is all very big.The parameter signal that need test of under balance pressure drilling is distributed on the different position, well site in addition, the technician needs to make an inspection tour on the well site at any time to watch and to write down these parameters, then these parameters are gathered, analyze, with control, the method for operating that determines next step, workload is very big, particularly at bad weathers such as wind, rain, snow, its workload is bigger.And carry out underbalance when control, particularly during well head pressure control, the aperture that can only utilize the reversal valve on the controlling box to regulate choke valve, pressure control is inaccurate, the under-balanced state instability.Present in addition every cover well head pressure control appliance all has been equipped with independently hydraulic power source, is unfavorable for unified operation.
Summary of the invention
For solving problems such as image data is inaccurate in the under balance pressure drilling process, control mode falls behind, technician's labour intensity is big, the purpose of this utility model is to provide a kind of under balance pressure drilling real-time monitor controller to society.
For achieving the above object, the real-time monitor controller of a kind of under balance pressure drilling that the utility model proposes is formed by being integrated in positive-pressure explosion-proof operating room (7) and explosive-proof hydraulic station (1) on the sled seat, be provided with pressure control device remote control box (2), well drilling parameter collection device (5), supervisory control comuter (3) and DVR (4) in the positive-pressure explosion-proof operating room (7), the input of supervisory control comuter (3) is connected with well drilling parameter collection device (5), and output is connected with pressure control device remote control box (2); Hydraulic Station (1) is connected with the lubricating oil pipe line of pressure control device remote control box (2) and rotating blowout preventer respectively by hydraulic line; Well drilling parameter collection device (5) is connected with a plurality of sensors that are distributed in the well site by signal-transmitting cable; Pressure control device remote control box (2) is connected with the choke valve of choke manifold and the pressure-control valve of rotating blowout preventer respectively by hydraulic line.
Because adopt such scheme, under balance pressure drilling monitoring and control device by integrated can obtain real-time parameter more accurately, and can utilize computer system to control in real time, keep desirable under-balanced state; In the control room, carry out underbalance monitoring, control operation, all right mitigation technique personnel's labour intensity.
