AI Technical Summary
Deep-water ultra-shallow gas wells are prone to wellbore fluid accumulation during the extraction process. Existing technologies are difficult to identify and remove in a timely manner, leading to a decrease in gas well production and unstable production. Moreover, operating in deep-water environments is costly and difficult to implement.
A device for early warning and rapid removal of liquid accumulation in deep-water ultra-shallow gas extraction is adopted, including a riser, casing, blowout preventer and a collaborative control device. It utilizes a critical liquid carrying rate calculation system, a data acquisition device, a liquid accumulation discrimination and intelligent early warning system and a bottom hole liquid dynamic removal device to monitor the wellbore flow status in real time. Through the synergistic action of bubbler injection and plunger liquid discharge assembly, the liquid accumulation is rapidly removed.
It enables timely identification and efficient removal of liquid accumulation in the wellbore, improves the production stability and drainage efficiency of gas wells, reduces the cost of deepwater operations, and reduces reliance on manual intervention. It is suitable for deepwater ultra-shallow gas wells and low-yield, low-pressure gas wells.
