中文摘要:四川盆地气藏不同程度的受水侵影响,普遍产水,气藏开发技术指标差异明显,采出程度差别大。为了更有效地提
高有水气藏开发后期调整措施的针对性,最大限度降低水侵影响,提高气藏采收率,迫切需要一套统一的开发技术指标评价体系。
针对四川盆地整装型有水气藏,围绕前期地质认识、中期优化生产及中后期措施治水3 个阶段,优选出气藏评价指标。基于综合
评价法评价思路,建立四川盆地整装型有水气藏开发技术效果评价体系,通过开展典型气藏开发效果评价,结果表明该体系具有
一定的实用性,能够达到定量、科学的评价气藏开发技术效果,为有水气藏开发提供指导性依据。

英文摘要:Affected by water invasion to some extent, most gas reservoirs in Sichuan Basin generally produce water. The indexes
of their development technologies and the degree of reserve recovery are quite different. For these water-bearing gas reservoirs, it's
essential to establish a unified evaluation system of these technical indexes in order to effectively improve the pertinence of the adjustment
measures in the later development stage, minimize the impact of water intrusion, and increase the recovery factor. So, taking
mono-block water-bearing gas reservoirs in Sichuan Basin as examples, we at first selected some evaluation indexes focusing on three
stages, i.e., geological understanding in the early, production optimization in the middle, and water control in the middle to later. Then,
we developed an effective system to evaluate development technologies. Finally, we assessed the development effects of typical gas
reservoirs. Results show that this system is practical, and can evaluate the effects of development technologies quantitatively and scientifically
so as to provide guidance for the development of water-bearing gas reservoirs.
