| 摘 要： | 胜利油气区浅层气藏以岩性为主，埋藏深度小于1500m，主要分布在上第三系馆陶组和明化镇组。储层为河流相沉积的透镜状砂岩，储层胶结疏松，且胶结物中的主要成分为泥质，大多数气藏都带有边水或底水。气藏开发时面临的主要问题是地层易出砂，井底易积液。与此对应的配套采气工艺技术是：先期防砂；安装井下活动气嘴；低压气井实施增压开采；排水采气。但是，目前气藏开发面临的出水问题仍比较突出。

| Abstract: | The shallow gas pools of Shengli Oilfield are lithological trap,its buried depth is less than 1500m and mainly located in Neogene Guantao and Minghua Formation.The gas reservoirs are fluvial lenticular loose sandstone with edge or bottom water.The major problems for development the gas reservoir are sand production and fluid accumulation at borehole bottom.A number of measures must be taken in order to realize reasonable development,including sand control before production,installation air tip at borehole bottom,production by booster in low pressure gas well and drainage gas recovery.At present,water production is serious during gas reservoir development.$$$$ |
