在油气初次运移研究中压实曲线的应用

作者提出解释压实曲线的动态分析法。用它研究压实曲线,能够获得许多不同于静态分析的结论,如排烃深度、排烃方向以及对生油岩的评价等等。本文利用这种方法研究了板桥凹陷初次运移的问题,获得了与地化和构造研究一致的结论。说明这种方法在实践中得到了初步证实。

APPLICATION OF COMPACTION CURVE IN RESEARCHING PRIMARY MIGRATION OF OIL AND GAS

The author suggests a method, trend analysis method, which can explain the compaction curve from historical view. Research for compaction curve by this method may acquire some conclusions, such as depth and direction of primary migration and evaluation of source rocks etc, which are different from that by the static state analysis method. In this paper, the problem of primary migration of Banqiao depression has been studied by this method. The results of this research coincided with that of geochemical and tectonic studies, which preliminarily illustrate that this method is proved to be true in practice.
