Problems solved by technology
However, since each object is controlled by multiple sets of independent control equipment, in case of unexpected danger, once the driller is affected by psychological quality or other factors, it may lead to the situation that the well shut-in operation cannot be carried out according to the well shut-in procedure, resulting in The risk of economic loss and personal injury cannot guarantee the safety and reliability of the system

The invention discloses a wellhead control system. The system comprises an execution mechanism used for controlling opening and closing of a wellhead, a detection device used for detecting operation state parameters, a controller controlling the execution mechanism according to an operation instruction to open and close the wellhead, and a control center for monitoring the state of the wellhead according to operation state parameters, forwarded by the controller, of the execution mechanism and sending the corresponding operation instruction to the controller when the state of the wellhead is abnormal. The state of the wellhead is monitored according to the operation state parameters of the execution mechanism, the execution mechanism is controlled according to the operation instruction when the state of the wellhead is abnormal so as to open and close the wellhead, drilling emergency well shut-in can be quickly implemented easily under the working condition during drilling, and safety and reliability of the system are better ensured.
Description
technical field [0001] The invention relates to the technical field of oil drilling, in particular to a wellhead control system. Background technique [0002] In the process of oil and gas exploration and development, when overflow, well kick or blowout occurs at the wellhead, it is necessary to close the wellhead of the oil and gas well through the independent controller of each object operated by relevant personnel such as drillers, so as to avoid blowout accidents. [0003] In general, drillers can implement well shut-in according to the well shut-in procedure for each working condition in the well control implementation rules. However, since each object is controlled by multiple sets of independent control equipment, in case of unexpected danger, once the driller is affected by psychological quality or other factors, it may lead to the situation that the well shut-in operation cannot be carried out according to the well shut-in procedure, resulting in The risk of econom...
