AI Technical Summary
In existing offshore high-temperature gas well production, wireline operations are limited by well inclination, and the hydraulic control sliding sleeve structure is complex and difficult to construct, affecting the stability and cost of gas well production.
Design a production sliding sleeve for high-temperature gas wells in offshore oil fields. It adopts an opening and closing structure that can be opened and closed by ball dropping and pressure testing. It includes a sliding sleeve body, a control cylinder, an opening hole and a closing part. It can be quickly opened and closed by ball dropping and pressure testing, and is suitable for different well types.
It enables rapid and convenient control of the production of sliding sleeves, adapts to different well types, reduces construction difficulty and cost, and improves operational convenience and timeliness.
