通过对国内外油气成藏模式典型实例的剖析,对同类实例的共性进行了概括和简化,将油气成藏模式归纳为5大类,进而提出了油气成藏模式的新定义。研究认为,油气成藏模式分析的要素包括油气藏形成的基础条件、动力介质、形成机制和演化历程等,成藏模式应是基于全部要素的复合分析,但各类成藏模式的建立方法和适用范围应与不同的勘探程度和研究程度相适应。在实际工作中,可根据资料的情况,以4种要素中的一种或多种为主线,兼顾其他要素,来分别建立盆地级、坳陷级、凹陷级或圈闭级的成藏模式。
Based on analyses of the case studies of typical hydrocarbon pooling patterns,five types of hydrocarbon pooling patterns are identified,and a new definition for the hydrocarbon pooling pattern is put forward in this paper.According to the study,the elements of hydrocarbon pooling include basic geologic conditions,drive force and medium,mechanism,and process of reservoir evolution,et al.Comprehensive analysis of hydrocarbon pooling patterns should be based on all these elements.Moreover,the method for establishment of each pooling pattern and its range of application should be in accordance with the levels of exploration and research.In practice,one or more of these four elements can be selected as the primary elements,with the others as secondary ones,to establish the hydrocarbon pooling patterns at basin,depression,sag and trap levels respectively.
