摘要
浅层气藏是指埋藏深度小于 15 0 0m的气藏 ,主要包括生物气、煤成气、油型气、水溶气等。目前已经发现的浅层气藏在我国分布非常广泛 ,其资源量也相当可观。据初步估算 ,我国浅层气资源总量为 (2～ 5 )× 10 12 m3(水溶气除外 )。文章介绍了以胜利油田为例的我国东部油区浅层气藏的主要地质特征和开发对策。其特征为 :储气砂体分布零散、但是储量又相对集中 ,每个储气砂体自成气水系统、气水关系复杂、储集层物性好 ;其开发对策主要包括以下 6个方面 :①前期地质综合研究 ;②科学编制开发评价方案 ;③先期防砂 ;④全过程气层保护 ;⑤配套采气工艺系列 ;⑥精细气藏描述。
Shallow gas reservoir is that buried depth is less than 1,500 meters, including biogas, coal-formed gas, oil-type gas and water-soluble gas etc. It is distributed widely in China, and resources amount is rather considerable. According to preliminary evaluation, there are about 2 to 5 trillion m3 of total resources, excluding that of water-soluble gas. Taking Shengli Oil Field as an example, this paper introduces some main geological characteristics. The distribution of gas-sand-bodies is sporadic, reserves in place are relatively centralized, each of it possesses a gas-water system, and its gas-water relationship is rather complex. The reservoir has better physical properties. The development strategies include 6 main aspects, that is, early comprehensive geological research, programming development evaluation scheme scientifically, initial sand control, all process gas formation protection, a set of gas production techniques, and fine gas reservoir description.
