Discussion on the Differential Distribution of WOC and its Mechanism in the Faulted Anticline Reservoir
摘要
Abstract
Based on the isochronous formation frame,the reservoir characteristics and oil & water distribution pattern of Es2(81)sand unit in Shenglicun faulted anticline of Shengtuo Oilfield are described by using of core data and close spacing log information. With the mechanical balance between the driving force and resisting force of petroleum accumulation,the mechanism of the differential distribution of WOC in faulted anticline reservoir is elaborated. The result shows that the oil column height and WOC depth in the same sand unit but different block are inconsistent in the faulted anticline reservoir,and the WOC in the same block is not parallel with the structural contour. The block and area with poorer physical property,smaller strata dip and higher oil density can hold higher oil column height,which causes the differential distribution of WOC in planar shape. In the actual reservoir,the regional difference of oil column height between blocks and in same block is a basic feature, and the situation of WOC is controlled by reservoir heterogeneity,structural attitude and oil density comprehensively.关键词
