从第29届国际地质大会看含油气盆地分析的某些进展

总结分析了第２９届国际地质大会上有关含油气盆地分析中某些方面的进展，主要包括：（１）弧后及大陆裂谷盆地、克拉通盆地、前陆盆地以及与走滑作用有关的盆地形成的地球动力学背景及形成机理分析；（２）利用砂岩岩石学和火山岩地球化学特征探讨盆地形成的构造背景及其演化；（３）层序地层学在分析沉积盆地沉积充填特征及历史、识别和预测储集砂体、预测源岩分布及有机质丰度中的应用；（４）盆地发育过程中主要地质作用的数值模拟；（５）油气生成、运移和聚集的数值模拟。

SOME PRGRESS IN PETROLIFEROUS BASIN ANALYSIS BASED ON THE DATA PRESENTED AT THE 29TH INTERNATIONAL GEOLOGICAL CONGRESS

Based on the data presented at the 29th International Geological Congress, some progress in petroliferous basin analysis has been briefly synthesized as follows, (1) the analysis of geodynamics and forniative mechanism for back-arc and continental rifting basins, cratonic basin, foreland basin and strick-slip-related basin;(2)discussion on tectonic setting and evolutionary history of sedimentary basins based on sandstone petrology and igneous rocks geochemistry, (3) the use of sequence stratigraphy in analysing sedimentary basin filling characteristics and history, recognizing rcservoir body and predicting the distribution of source rocks; (4) computer simulation of main geological processes and events through basin generation, formation and development; (5) modeling of hydrocarbon generation, migration and accumulation.
