印尼K区块中下侏罗统储层流动单元研究

Research on Flow Unit of Middle and Lower Jurassic Reservoir in Indonesia K Block

以印尼K区块R组海相砂岩储层为研究对象,结合国内外流动单元研究现状,分析了岩心、测井和储层物性等,对R组储层流动单元的划分、特征、控制因素等进行了研究。分析结果表明:采用FZI法可将印尼K区块R组划分为7种流动单元类型,不同流动单元物性差别较大,其中HFU-6和HFU-7是研究区最有利流动单元类型。通过对工区数据分析可知,工区流动单元受沉积环境和成岩作用的影响较大,在区域上,工区从南向北有利流动单元分布厚度逐渐增大。

Take the marine sandstone reservoir of R group in Indonesia K Block,combine with the foreign and domestic research status about flow unit and based on the analysis of information such as core,logging and reservoir physical property to research on the division,characteristic and controlling factor of flow unit of R reservoir.The analysis results show that the R group in Indonesia K Block can be divided into 7flow unit types according to FZI method,physical property difference between different flow units are large and among them,the HFU-6and HFU-7are the most favorable flow unit types in the research area.According to the data analysis of working area,the sedimentary environment and diagenesis have large influences on the flow unit in working area and in terms of area,the distribution thickness of favorable flow unit within the working area is gradually increasing from south to north.
