Abstract

Abstract:

The evaluation method of storage capacity expansion and design production realization is key to achieving efficient underground gas storage （UGS） operation and predicting the future UGS state. In order to understand the operational rules of UGS storage capacity expansion and design production realization，this paper investigates the J gas storage，a UGS of gas cap reservoir as an example. Based on tracking the basic UGS production data and analyzing the development performance of the gas reservoir，this paper analyzes the multi-cycle injection and production operation data of the UGS and evaluates the pressure，storage capacity，gas production capacity of wells and injection-production operation performance of the UGS，using the dynamic evaluation technology of UGS in gas fields. The main factors affecting the storage capacity expansion and design production realization of the J gas storage are clarified. It is suggested that the J gas storage is transitioning from the capacity expansion stage to the stable stage，but the subsequent storage capacity expansion is challenging，because the drainage well fails to drain normally with gas channeling in the reservoir. It is necessary to perform fine reservoir description of the UGS to clarify the reservoir sand body distribution pattern and identify gas channels. Meanwhile，numerical simulation shall be done to develop a reasonable injection-production scheme to avoid impacts of gas channeling in drainage wells and resume storage capacity expansion. A method for evaluating the UGS capacity expansion and production realization has been developed，which provides technical support and references for the construction of similar UGS facilities and realization of UGS storage and production capacity targets.

摘要：

扩容达产评价方法是实现储气库高效运行及预测储气库未来状态的技术关键。为明确储气库扩容达产运行规律，以J气顶油藏型储气库为例，在跟踪储气库生产基础数据和对气藏开发动态研究的基础上，运用气藏型地下储气库动态评价技术，通过分析储气库多周期注采运行数据，开展了储气库压力、库容、单井采气能力、注采运行效果等评价研究，揭示了J储气库扩容达产的主要影响因素。分析认为J储气库正从扩容阶段向稳定阶段过渡，但因排液井储层气窜，无法正常排液，导致后续扩容工作困难；需要针对储气库进行储层精细描述工作，厘清储层砂体展布规律，明确气窜通道；同时，结合数值模拟技术，设计合理注采制度，规避排水井气窜影响，恢复扩容工作。研究形成了气顶油藏型储气库扩容达产评价方法，为后续同类型储气库的建设及储气库的达容达产评价提供一定的技术支撑和借鉴。
