摘要
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。
Most of oil - gas bearing basins in our country belong to superimposed basin, which is characterized by multiple - layer structure and complicated distribution of oil - gas pools. Our study of these superimposed basins has made progress that can be summarized as 4 points. (1) Finishing deep wide angle seismic reflection/refraction survey across the Tarim basin and Tianshan Mountains. (2) Illustrating the Mesozoic structural and sedimentary coupling between the Kuqa basin and Tianshan Mountains. ( 3) Making necessary theoretical preparation for search and evaluation of well developed marine source rocks. (4) Getting new knowledge about effect of deep fluids on petroleum generation, multiple inpouring from various source rocks, and process to form deep reservoir in carbonate rocks.
