Research on Well Control RisksofSteel WireLiftingand Drainage Fluid Recovery Technology forGas Wells

LI Fugui1 CUI Yong² XIE Jingxin1 WANG Mingsa1 1.Zhonghai Xingfa （Guangdong） Safety Technology Services Co.，Ltd.，Guangzhou，GuangdongProvince，510000 China; 2.Dekma （Tianjin） Technology Development Co.，Ltd.， Tianjin，3Ooo4O China Abstract：The stel wire lifting and drainage technology for gas wels is an effective method to restore production capacityof shut in wels withlow liquidaccumulation，but therisk of wellcontrol is prominent during its operation.The system analyzed wellcontrol risk foutors in the implementation of this technology，mainly including dynamic changes in wellhead pressure，blowouts，and tool string topping. By evaluating existing wellcontrol measures，problems such as unreasonable equipment configuration， insuficient maintenance，outdated monitoring technology，and management execution deficiencies were revealed，and corresponding optimization recommendations are proposed.The research results provide theoretical support for the development of wellcontrol safety standardsand the improvementofoperational reliabilityand asistinthesafepromotionandapplicationof this technology.
