基于成岩储集相定量分类模式确定特低渗透相对优质储层——以AS油田长61特低渗透储层成岩储集相定量评价为例

针对陕北斜坡中部特低渗透储层受沉积环境、成岩作用及构造等因素影响,成岩过程压实和胶结作用强烈,储层储集性能和渗流结构差异大的特点.利用AS油田长61特低渗透储层成岩储集相定量分类模式圈定相对优质储层,分别进行了区块长61砂岩的成岩作用和孔隙演化分析,建立了不同类别成岩储集相定量分类模式与综合评价指标体系.不同类型成岩储...

Based on the Quantitative Classification Mode of Diagenetic Reservoir Facies to Filter Relatively Excellent Quality: Taking the quantitative assessment of diagenetic facies of Chang 61 reservoir of AS oilfield hyposmosis reservoirs for an example

The reservoir in Shannbei structural slope is affected by the depositional environment,diagenesis and structural factor,so the compaction and cementation effects are intense in Shanbei slope center.In this paper relative high quality reservoirs of hyposmosis reservoir were filtered,in which diagenetic reservior facies mode of quantitative classification of Chang 61 reservoir in AS oilfield of extra-low permeability was used.With the work of sandstone diagenesis and porosity evolution analysis of Chang 61,di...
