裂谷盆地古地貌对沉积体系充填的影响分析

Analysis on the Influence of Rift Basin Ancient Landform on Sedimentary System Filling

以渤海湾盆地为研究区,通过对构造坡折带以及转换带的特征分析,得到以下结论:1盆地中的成油组合和含油气系统要按各阶段分别研究,对不一样的油源或者运移通道要进行综合研究;2油源的研究,应针对不同类型的有机质,在经历不同温度和压力的变化,来综合判断它的丰度;3今后勘探领域要扩展到碳酸盐岩分布区,以台地为突破口,研究其与滨海、大陆坡之间的关系,由此把握油气的分布规律。

Taking Bohai bay basin as the study area, through analysis of the characteristics of tectonic slope -break zone and the transformation zone, we get the following conclusions：①the oil-bearing group and petroleum system in the basin should be studied by stage respectively, and different oil sources and migration channels should be comprehensively researched;②for the study of oil source, we should judge the abundance accoixding to different types of organic matter, after the change of different temperature and pressure;③the next exploration areas will be expand to the carbonate distribution area, with platfomi as the breakthrough point, to study the its relationship with coast and continental slope, thus grasping the distribution rule of oil and gas.
