摘要
本文以泥岩压实研究为基础,(1)计算了陕甘宁盆地西缘白垩系剥蚀厚度和原始沉积厚度,并对不同地区和不同断层在白垩纪的活动性进行了比较;(2)根据计算出的流体压力,探讨了研究区过剩压力纵向分布和水平分布的特征;(3)以过剩压力分布为基础,参考地层水矿化度、水型等资料,初步分析了已知油井与水动力条件间的关系。
Based on the study of mudstone compaction,1.the erosion and the deposit thicknessof the Cretaceous in Shaanxi-Gansu-Ningxia Basin are calculated and the activity for dif-ferent places and different faults in the Cretaceous are contrasted;2.the characteristics ofexcessive pressure both in vertical and horizontal distribution are discussed according tothe fluid pressure calculated;3.the relation between known oil-bearing situation and hy-drodynamic condition were analysed on the basis of excessive pressure distribution and re-ferring to the water salinity and type.
