大港油田地下储气库可行性研究

通过对大港油田已枯竭的板８２０气藏的更加深入的地质研究，重新评价了该气藏的储集层和盖层，论证了作为地下储气库的地质可行性；通过对开发史分析研究，论证了作为地下储气库的开发可行性，并计算了气藏开发动态储量。根据多年来对天津市供气规律，确定了储气库调峰周期和基本参数。设计了注采井生产能力和注采方案。根据经济评价，认为利用废弃气藏作为地下储气库经济效益显著。图２表１（郭海莉摘）

Geological feasibility study for underground gas storage in Dagang oil field.

As a result of comprehensive geological research for depleted Ban 820 gas reservoir, in injection and withdrawal, coupled with given reevaluation of the reservoir, cap formation and its behavior, it has proved that it is geologically feasible to take it as an underground gas storage. Both development feasibility in gas storage and the development dynamic reserves of gas reservoir are calculated through the study of development history. According to our experience in supplying gas from storage to Tianjin city for many years, the peak demand period and basic parameters of storage have been determined, the production capacity of injection/withdrawal wells and injection/withdrawal plan has also been designed. Accordingly, it is economically feasible to utilize abandoned gas reservoir to build gas storage project in terms of economic evaluation, potential capacity of gas storage and service facility.
