摘要
针对中国复杂地质条件和储气库周期性大流量强注强采交变载荷工况,建立了包括选址评价、指标设计、钻完井、地面工程、风险预警和评估等方面的气藏型储气库建库关键技术,并总结了矿场应用实效。建立了开发中后期构造破碎气藏建库选址圈闭密封性评价技术,提出了以非均质水侵储集层有效库容量设计为核心的建库关键指标设计方法,建立了适应超深超低压地层和交变载荷工况的安全钻井、高质量固井技术和高压大流量地面注采工程优化技术,实现了高压注气压缩机等储气库地面核心装备国产化,建立了储气库地下、地面全系统风险预警和评估技术。5项关键技术成功应用于新疆呼图壁等6座气藏型储气库群的选址、设计、建设和运行,方案设计主要指标与实际动态高度吻合,已建成调峰能力超过75.0×10~8 m^3,实现了建设和运行高效且零事故。
In view of complex geological characteristics and alternating loading conditions associated with cyclic large amount of gas injection and withdrawal in underground gas storage（UGS） of China,a series of key gas storage construction technologies were established,mainly including UGS site selection and evaluation,key index design,well drilling and completion,surface engineering and operational risk warning and assessment,etc.The effect of field application was discussed and summarized.Firstly,trap dynamic sealing capacity evaluation technology for conversion of UGS from the fault depleted or partially depleted gas reservoirs.A key index design method mainly based on the effective gas storage capacity design for water flooded heterogeneous gas reservoirs was proposed.To effectively guide the engineering construction of UGS,the safe well drilling,high quality cementing and high pressure and large flow surface injection and production engineering optimization suitable for long-term alternate loading condition and ultra-deep and ultra-low temperature formation were developed.The core surface equipment like high pressure gas injection compressor can be manufactured by our own.Last,the full-system operational risk warning and assessment technology for UGS was set up.The above 5 key technologies have been utilized in site selection,development scheme design,engineering construction and annual operations of 6 UGS groups,e.g.the Hutubi UGS in Xinjiang.To date,designed main indexes are highly consistent with actural performance,the 6 UGS groups have the load capacity of over 7.5 billion cubic meters of working gas volume and all the storage facilities have been running efficiently and safely.
