边底水气藏的开发相对较为复杂,采收率远远低于气驱气藏。因此,结合典型气藏提出提高采收率技术对策建议应是合理开发此类气藏的关键。通过对国内外典型边底水气藏的调研,在了解气藏地质特征的基础上,总结了气藏的注水、注气、加速降压等主要开发方式,并对国内外新型堵水、排水采气等工艺措施进行归纳,最后结合实例提出边底水气藏消除和延缓水害等相应的技术对策建议,对高效合理开发边底水气藏具有一定指导作用。
The development of edge-water reservoirs is relatively complicated, and the recovery rate is far lower than that of gas-driven gas reservoirs. Therefore, it is the key to develop such gas reservoirs rationally to propose the technical countermeasures to improve oil recovery combining with typical gas reservoirs. Based on the investigation of the typical edge water reservoirs at home and abroad, based on the understanding of the geological characteristics of gas reservoirs, the main development methods of water injection, gas injection and accelerated depressurization of gas reservoirs are summarized. Gas production and other technological measures are summarized. Finally, the corresponding technical countermeasures for eliminating and retarding water damage at the edge of the reservoir are put forward in combination with examples, which is of guiding significance for the efficient and reasonable development of the edge water gas reservoir.
