砂泥互层地层断裂带结构特征及控油作用
Sandstone-mudstone interbed fault zones structure feature and controlling oil effect
摘要
Abstract
By using outcrop dissection,3-D seismic interpretation,logging curve comparison,core observation and rock thin section identification,we studied the internal structure of the fault zones in sandstone-mudstone interbed strata of the Putaohua reservoir in northern Xingbei Oilfield,Songliao Basin.Based on the comprehensive responses of well logging,a model to predict fault zone thickness was established;with it we discussed how the fault structure controlled the distribution and enrichment of remaining oil along the fault edges.Our results reveal that the fault zones are mainly composed of a fault core and the damage zones;the fault core develops segmented structure of shale smear,while damage zones show features of crushing,sliding and deformation;the fault segments vertically into PI4 stratigraphic horizon,causing the three breakpoints in the coring well drills,where breakpoint 1 develops fault tip damage zones of sandstone deformation band,breakpoint 2 develops the major fault core of shale smear,and breakpoint 3 develops argillaceous breccia and minor fault core of mudstone fractures filled by calcite.With increasing distance to the fault core,the density of minor fractures and carbonate content are gradually reduced.关键词
