Description

Well control liquid level control and perfusion device Technical Field The utility model relates to the field of auxiliary tools for petroleum drilling, in particular to a well control liquid level control and pouring device. Background Well control liquid level control and filling devices are generally used in safety management of oil and gas wells, and particularly in the drilling operation process, are important equipment for ensuring stable wellhead pressure and preventing accidents such as blowout, but when the filling device on the market is used for realizing the filling operation of drilling fluid, the filling device does not have the setting of a quantitative function, and the filling amount of the drilling fluid during filling can not be ensured. Aiming at the problems, the prior patent provides a drilling fluid filling device with a precise quantitative function (publication number: CN 213360060U), wherein the infrared distance sensor calculates the filling liquid level of the drilling fluid and feeds the filling liquid level back to the control terminal when the filling time reaches the time regulated and controlled in advance through the arranged infrared distance sensor, the control terminal and the electromagnetic valve, and then the control terminal controls the electromagnetic valve to start so as to close a liquid feeding channel of the drilling fluid, thereby completing the precise quantitative filling operation of the whole drilling fluid and effectively avoiding the overflow phenomenon of the drilling fluid caused by filling; However, in the practical use process, the technical scheme has the advantages that larger vibration occurs in the construction process, the detection accuracy through infrared rays is lower, if vibration deviation occurs in the position of the infrared distance sensor, the infrared rays incline, abnormal injection of drilling fluid is extremely easy to cause, the construction is influenced, meanwhile, due to the lack of an indicating mechanism, the change of the wellhead liquid level is difficult to observe and alarm timely, namely, the condition of the well liquid level cannot be quickly reacted and judged, and the technical defect is overcome.
