我国含油气盆地多属叠合盆地,具有多层结构,油气藏的分布状态复杂。本项目有针对性地开展研究,在4方面取得了进展:(1)完成天山-塔里木盆地基干剖面地震宽角反射/折射野外探测;(2)揭示出库车坳陷-天山盆山体系的新生代构造与沉积耦合特征;(3)为寻找和评价优质海相烃源岩做了理论上的初步准备;(4)在叠合盆地深部流体的成藏效应,多套烃源岩混合充注和深部碳酸盐岩储层形成机理等方面取得了新认识。
The petroliferous basins in our country are mostly superimposed basins with multi-layer structure, and the distribution of oil and gas reservoirs is complex. This project has carried out research in a targeted manner and made progress in four aspects: (1) completing the wide-angle reflection / refraction field detection of the Tianshan-Tarim Basin seismic profile; (2) revealing the freshmen of the Kuqa Depression-Tianshan Basin mountain system (3) a theoretical preliminary preparation for the search and evaluation of high-quality marine source rocks; (4) the reservoir-forming effect of deep fluids in the superimposed basins, and the mixing of multiple sets of source rocks And the formation mechanism of deep carbonate reservoir has made new understanding.
