The invention relates to the technical field of oil field exploitation. In order to solve the technical problem that the pressure monitoring device in the prior art cannot allow users to observe the change of pressure data in real time, and has hidden safety hazards when operating in a high-pressure water well, the invention provides a high-pressure water well For the pressure drop monitoring device, a pressure sensor is arranged on the outer surface of the shell, a display screen is set inside the cavity composed of the front cover, the shell, and the back cover, and an explosion-proof screen is set at the opening end of the cavity, and the pressure The end of the sensor connected to the high-pressure water well is provided with a high-pressure sealing ring, so that the user can observe the pressure data collected by the pressure sensor in real time through the explosion-proof screen, and the explosion-proof screen and the high-pressure sealing ring can also ensure the operation of the high-pressure water well pressure drop monitoring device. security at the time.
Description
technical field [0001] The invention relates to the technical field of oilfield exploitation, in particular to a pressure drop monitoring device for a high-pressure water well. Background technique [0002] In the process of oilfield exploration and development, monitoring the pressure drop of water injection wells is an important means and effective method to understand and understand the dynamics of reservoirs in the formation, and it has made great contributions to the secondary development of oilfields. However, with the improvement of monitoring technical requirements, some deficiencies have also been exposed in monitoring engineering. [0003] For low-permeability oilfield high-pressure water injection wells in oilfield development, the wellhead water injection pressure is greater than 25Mpa. The traditional method of monitoring the pressure drop of high-pressure water wells is to use conventional well test blowout preventers and close the pressure gauge at the wellhe...
