【摘要】 克拉美丽气田是近年来准噶尔盆地天然气勘探的一个重大发现。针对该气田火山岩气藏内幕结构复杂,储层非均质性强、井间产能差异大的特征,提出了动静态资料相结合的气井连通性分析方法:首先利用试井、试采及油气水性质等动态资料从开发角度对相邻井进行井间连通性分析,然后结合地质以及地震资料对火山岩体轮廓和内幕结构精细刻画的成果,进一步确定井间连通情况。以滴西18井区为例,采用上述气井连通性分析方法分析认为:DX182、DX1824是连通的,DX1804可能与DX18或者DX1805连通,其余井间的连通性较差。在研究区的应用结果表明,该分析方法对单井开发动态趋势预测与实际符合率达到80%以上,为克拉美丽气田开发方案的编制提供了可靠的基础数据。更多还原

【Abstract】 The Kelameili Gas Field,another major discovery in natural gas exploration in the Junggar Basin,is featured by complex internal structures,heterogeneous reservoirs and great disparities in gas production capacity among different wells.In view of this,a new method is proposed to analyze the well connectivity through both dynamic and static data.First,the well connectivity of neighboring wells is discussed from the development perspective based on the well-testing and trial production data and the properties of oil,gas and water of these wells.Then the details of well connectivity are determined by referring to the fine descriptions of the profile and internal structures of volcanic rocks in this area based on geological and seismic data.In a case study from the wellblock Dixi 18,this analysis method showed that good connectivity was found between DX182 and DX1824 wells;possible connectivity existed between DX1804 and DX18 or DX1805 wells;but the inter-well connectivity among other wells were very poor.In conclusion,the prediction of the dynamic trend of a single well’s development in this study area agrees well with the actual result with the accuracy ratio of more than 80%,providing basic data for formulating a proper development plan of the Kelameili Gas Field.更多还原
