通过岩石物理手段分析大港油田ZY地区孔二段的低阻油层成因,认为岩性较细导致的高束缚水是该区形成低阻的主要原因。据此利用可动水分析方法复查该区低阻油层。首先利用核磁资料确定束缚水孔隙度,继而利用测井计算所得的粒度中值信息和孔隙度信息建立本区束缚水饱和度计算模型,运用该模型处理了研究区15口井,发现了部分漏失的油层,取得了较好的复查成果。
By means of petrophysical analysis, the origin of low-resistivity reservoirs in Kong2 Member of ZY area in Dagang Oilfield is analyzed. It is considered that the high irreducible water caused by the thin lithology is the main reason for the low resistivity formation in this area. Based on this, we can use movable water analysis to review the low resistivity reservoir in this area. Firstly, using NMR data to determine the irreducible water porosity, and then using the median grain size information and porosity information obtained from well logging to establish the irreducible water saturation model in this area. Using this model, 15 wells in the study area were identified and some of them were found Of the reservoir, made a good review of the results.
