摘要
油气初次运移方向主要取决于过剩压力的展布;'积聚型'和'连续型'可能是欠压实与正常压实的两种不同排烃方式;排烃带的确定划分不能单纯依据压实法定论,尚须结合地化法综合考虑;异常高压带在烃类运聚中有排烃和盖层两种作用。用地化法与压实法相结合是研究排烃运移的有效途径。
Co-authors believe that direction of primary migration is fundamentally governed by differential pressure of source rocks to their surrounding rocks. Therefore the interval of abnormal pressure could either expel hydrocarbons generated by it or prevent hydrocarbons produced bv other intervals from migrating into it or both.The so called accumulating style of expulsion and continuous style might be different response to undercompaction and normal compaction of source rocks respectively. In addition, this paper emphasizes the approach from stand point of geochemistry as well as approach of compaction in study of hydrocarbon expalsion and migration.
