中文摘要:
      通过对鄂尔多斯盆地沉积及油气成藏特征的详细分析,该地区差异压实作用过程可分为压实排水、压实排烃、弹性压实三个阶段;差异压实作用不仅受到砂泥比等沉积物类型及含量的影响,古地貌也是重要的影响因素;差异压实与岩性、区域构造、古地貌等因素的共同作用可形成不同的有利圈闭类型,对差异压实作用及其有利圈闭类型的认识,有利于深入寻找油气资源及合理开发油气藏。
英文摘要:
      Ordos Basin is an important oil and gas exploration and development area in china, Oil and gas structures are formed by compaction in multiple horizons. By the influence of the ancient landform, the differential compaction structure and other structures combine to form various types of oil and gas reservoirs, which are rich in oil and gas resources. Based on the detailed analysis of sedimentary and hydrocarbon accumulation characteristics in Ordos basin, the process of differential compaction in this region can be divided into three stages: compaction and drainage, compaction and hydrocarbon expulsion and elastic compaction; The effect of differential compaction is not only affected by the type and content of sand and mud, but also by the paleogomorphology; Different types of favorable traps can be formed by the combination of differential compaction and lithology, regional structure and paleogeomorphology. The understanding of differential compaction and favorable trap types is beneficial to the deep exploration of oil and gas resources and the rational development of oil and gas reservoirs.
