摘 要 针对因高泥、高钙、薄互层等非均质性较强引起的特低渗透砂岩储油层,
ABSTRACTAccording to ultralow permeable sandstone reservoir caused by heterogeneity like high mud andcalcium content and thin interbeds ,
采用多种合理的方法研究有效厚度物性标准,
this paperuses several reasonable method to study the criterion of the effectivethickness.
各种方法优、缺点互补，较客观地确定下限。
The methodscomplement each other to objectively determine the cut off .利用多条相关电测曲线识别储层岩性、物性及含油性,
Lithology ,rock property and oil content are identified by using several relative electriclog curves.
即采用“多参数逐步判别法”制定有效厚度电性标准。
That is to say, the electric criterion of effective thickness is determined by using“Multi-parameterand step-by-step determination method”.
较好地解决了特低渗透砂岩储层有效厚度的划分问题。
This can solvethe problem of plotting the effective thickness of very low permeable sandstonereservoir.
