摘要
新场气田须二段气藏目前产水量大,这对开发工作造成了较大影响。因此,从气藏连通性出发,对气藏动态储量进行了计算,并从水侵强度、水侵量、气井出水类型等方面对气藏水体特征进行了初步分析,认为该气藏属中弹性水驱气藏,水侵量较大,气井出水为衡侵—纵窜型。吸取国内外类似气藏的开采经验,对新场气田须二段气藏的合理开发提出了建议。
A lot of water produced from Xujiahe 2 Member gas reservoir in Xinchang gasfield brings about a severe effect on field development.So,in this study,reservoir connectivity of the member was analyzed at first;and then its dynamic reserves were calculated;thirdly,waterbody characteristics were also researched in terms of water invasion intensity and production along with water-produced type;and it is considered that Xujiahe 2 reservoir,with a large amount of water invasion,belongs to an elastic water-drive gas reservoir and water produced from gas wells is of types of both balanced invasion and longitudinally channeling;at last,some suggestions on a reasonable development of Xujiahe 2 reservoir were made based on some experiences from similar gas reservoirs at home and abroad.
