Recently, the SHB5-14H well was undergoing temporary plugging and staged acid fracturing construction.

The open-hole section of Well SHB5-14H is 1010 meters long.

In the past, when implementing the temporary plugging staged acid fracturing process, only the pressure rise during on-site construction was used to judge whether the temporary plugging was successful or not.

The "wellbore stethoscope" technology has the following technical characteristics: rapid analysis of pressure wave response characteristics, judgment of the bottom hole event location; the use of patented analysis modules to improve signal accuracy and processing speed
