Abstract

The invention relates to a well control pressure monitoring device and method and belongs to the technical field of drilling construction. The device mainly comprises an anti-explosion shell, a pressure sensor, a temperature sensor, a temperature-pressure acquisition module, a microprocessor, control software, a storage module, a data teletransmission unit, a touch screen display system, a control unit, a quick relief unit, an internal reversible battery and a power adapter. The inside of the anti-explosion shell is divided into a high pressure chamber and an electronic chamber. The pressure sensor and the temperature sensor are mounted within the high pressure chamber; the quick relief unit is bypassed; maximum operating pressure is 100MPa. During using, a corresponding tubing thread is abutted to equipment to be tested, and the quick relief unit is connected to an inlet liquid storage tank of a pressure test pump through a high pressure hose. The electronic chamber is an anti-explosion normal pressure chamber; the temperature-pressure acquisition module, the microprocessor, the storage module, the touch screen display system and the internal reversible battery are mounted inside the electronic chamber. The data teletransmission unit is an independent anti-explosion packaging unit and is abutted to an instrument chamber to allow data teletransmission during usage.

Description

technical field [0001] The invention relates to a well control pressure monitoring and recording device and a monitoring and recording method, belonging to the technical field of drilling and production. Background technique [0002] The pressure-bearing equipment and well control equipment at domestic and foreign drilling and production sites must be pressure-tested before official operation. If they fail to meet the standard requirements, they must be rectified before pressure-testing, otherwise it will bring disastrous consequences. Therefore, major accidents are caused every year. The reason is that in the past, the equipment pressure test process was in a state of manual observation and recording, and detailed data was often omitted due to negligence, and the pressure test data was often changed artificially due to lack of attention, or the pressure test was not carried out in accordance with the prescribed procedures and standards , leading to disasters caused by the ...
