岗巴-定日盆地是在稳定的大陆边缘发展起来的.其中古生界为一套稳定的深海、浅海相碳酸盐岩及碎屑岩沉积,老第三纪则接受了一套残留海盆相的碳酸盐岩沉积.由于海水的频繁进退,构成了多套生储盖组合.侏罗纪、白垩纪及老第三纪生储盖条件较好,具有较理想的成油地质条件.后期改造不太强烈,保存有较好的局部构造,且多为背斜、断鼻、断块.保存条件各异,东部比西部好.研究表明,该盆地是一个具有一定前景的含油气盆地.
The Gamba-Dingri Basin was developed on a stable continental margin, in which the Paleozoic is a stable set of deep-sea and shallow marine carbonate and clastic sediments, and the Oligocene accepted a set of remaining basins Facies carbonate sediments, forming multiple sets of reservoir-cap assemblages due to the frequent advance and retreat of seawater.The Jurassic, Cretaceous and Oligocene tectonics have good reservoir-forming conditions and have ideal oil-producing geological conditions. The later alteration is not too strong, and the local structure is well preserved, mostly anticline, broken nose and fault block, with different preservation conditions and better eastern part than the western part.Research shows that the basin is a promising petroliferous basin .
