Research and Application of Pressure Operation Device for Gas Well

Gas wells under pressure generally have the characteristics of strong reservoir sensitivity. The use of conventional well killing operations will cause damage to the reservoir such as water sensitivity, water lock, etc., reduce permeability, and reduce production. Gas wells under pressure operation technology can solve the above difficulties. While domestic gas wells under pressure operation technology is mostly imported. In order to improve the research and development capability and technical level of domestic gas wells under pressure operation, we independently researched and formed a set of gas well under pressure operation equipment, which has airtight shackles and liquid-sealed gas decompression And other functions, it can realize the gas well under pressure operation requirements within the wellhead pressure of 14MPa. After the mine field test, various performance indicators meet the field requirements.
