【摘要】：从储气库与气藏在开采方式和运行规律方面的差异性出发,考虑气藏型储气库建库评价技术的特殊性和复杂性,提出了储气库特色建库评价关键技术,并进行了矿场应用实例分析。通过总结国内第1批商业储气库建设运行经验,深入研究储气库短期大流量往复注采的内在机理,提出圈闭动态密封性、建库有效孔隙空间、高速不稳定渗流有限供给等理念,创建了圈闭密封性评价、库容参数设计、注采井网优化和监测方案设计4项储气库特色关键技术,分别解决储气库保存条件、容量大小、高效注采、安全运行方面的技术瓶颈,丰富和完善了气藏型储气库建库地质方案设计技术体系。这些技术成功指导了某气藏建库地质方案设计和现场工程实施,扩容达产效果好,实际动态与方案设计指标吻合程度高。
[Abstract]:Based on the differences between gas storage and gas reservoir in production mode and operation law, considering the particularity and complexity of the evaluation technology of gas reservoir construction and storage, the key techniques of building and evaluating gas reservoir with characteristics are put forward.An example of mine application is analyzed.Through summing up the first batch of domestic commercial gas storage construction and operation experience, deeply studying the internal mechanism of short term large flow reciprocating injection and production of gas storage, putting forward the concepts of trap dynamic sealing, building effective pore space, high speed unstable seepage limited supply and so on.Four key technologies of trap sealing evaluation, reservoir capacity parameter design, injection-production pattern optimization and monitoring scheme design are established to solve the technical bottlenecks in storage conditions, capacity size, high efficiency injection and production, and safe operation, respectively.It enriches and perfects the geological scheme design system of gas reservoir.These techniques have successfully guided the geological scheme design and field engineering implementation of a certain gas reservoir construction and reservoir construction. The effect of capacity expansion is good, and the actual performance is in good agreement with the design index of the scheme.
