从波动观点看塔里木盆地的成藏演化史

A STUDY ON THE EVOLUTION OF RESERVOIRS IN TARIM BASIN IN THE VIEW OF EARTH′S CRUST WAVE MOVEMENT

在介绍波动分析概念及技术思路的基础上，利用波动模型下的埋藏史研究塔里木盆地的二次生烃过程。通过塔中和塔北地区的典型油气藏成藏史分析，发现早古生代晚期的长时期抬升剥蚀是塔中和塔北地区的重要成藏控制因素。并从波动特征控制盆地多期叠合发展的角度探讨了多旋回盆地决定多期生烃、多期成藏的过程，盆地升降运动对油气藏的破坏作用，差异沉降使构造溢出点改变，导致油气再次运移，成藏及成藏期后的沉降对油气性质改变的控制作用。最后结合塔里木盆地的石油地质条件分析，从波动观点探讨了塔里木盆地油气分布规律，指出塔中隆起西北倾没部位是寻找原生油气藏的有利场所。

Based on the analysis of wave processes and their approach,the secondary generation of hydrocarbon was studied by the buried history of the wave model in this paper.And the analysis of typical oil and gas reservoir formation in the central and north part of the Tarim Basin proves that uplifting at the late Palaeozoic is the controlling factor for the reservior formation in these areas.From the viewpoint of wave process controlling the mutiple superposition of the basin,the author discussed that the multiple cycle development of a basin controls the multiple generation of bydrocarbon,mutiple reservior formation,the destroy of reservoir by uplift and subsidence,the change of structrual spillpoint by differential subsidence result in the remigration,the change of oil and gas quality by subsidence while the reservoir formed or after that.The distribution of oil and gas in Tarim Basin was discussed by the wave theory,combining with the analysis of petroleum characteristics of Tarim Basin,pointing out that the plunging section of north west part of Tazhong uplift is a favorable area for exploring the primary reservoir,and the non structure reservoir at the north and south part of the Manggar sag is also an important domain for exploration.
