摘要:
呼图壁储气库设计库容107×108 m3,目前为全国最大的储气库,是在原呼图壁气田基础上建设起来的枯竭气藏型地下储气库。储气库气藏中部深度3 585 m,温度92.7 ℃,原始地层压力33.96 MPa,建库前地层压力系数0.46,注入气含CO2腐蚀性气体,整个气库共布注采井30口,单井注采气量大。为保证气井长期生产安全,依据钻完井井身结构和完井投产工艺特点,优化设计了注采井和监测井的井身结构,同时优选了配套井下工具,使注采井仅包含永久式封隔器、井下安全阀等少量井下工具,去除了循环滑套和伸缩短节,减少了管柱的可能漏失点,提高了管柱的可靠性。4个注采周期的安全生产实践证明,完井管柱和井下工具设计优选是合理的。
Abstract:
The Hutubi gas storage with the design capacity of 107×108 m3, which based on exhausted gas reservoir, now is the country′s largest gas storage. In this gas reservoir, the formation depth is 3 585 m, the formation temperature is 92.7℃, original formation pressure is 33.96 MPa, the formation pressure coefficient before the construction of Hutubi gas storage is 0.46, the injected gas contains the corrosive gas CO2, and the unmber of injectionproduction wells is up to 30 with larger injectionproduction volume for single well. To ensure the safety of the injectionproduction process for a long time, the wellhole structure of the injectionproduction wells and the monitoring wells has been optimal designed, and downhole tools has been preferred selected on the basis of drilling and completion wellhole structure and production process. The wellhole structure of the injectionproduction wells just contain a small amount of downhole tools such as permanent packer、subsurface safety valve, but leaving out the circulating sliding sleeve and telescopic joint, this design can reduce the tubing string leakage points and improve the reliability of the strings. The safety production practice of the four injectionproduction cycles proved that the design optimization of completion strings and downhole tools is reasonable.
