Description

technical field

[0001] The invention relates to the technical field of pressure recovery testing, in particular to a device and system for realizing pressure recovery testing of oil wells by monitoring changes in liquid surface depth and casing pressure. Background technique

[0002] The pressure recovery test is to understand the change trend of the formation pressure with time from the shutdown of the oil well in normal production. The pressure recovery test is the most commonly used unstable well test technology in the pressure recovery test. This technology is widely used in the petroleum industry. Oil well pressure recovery test with liquid level monitor is the most commonly used and most effective method in unstable well test. It has been widely used in various oil fields and has gradually replaced the costly downhole pressure gauge test mode.

[0003] However, the currently widely used on-site instruments and equipment for monitoring liquid level depth and casing pres...
