| 摘 要： | 思茅坳陷存在古生界和中一新生界两套沉积盖层，具有多套生储盖组合。以二叠系、三叠系为主力烃源岩，储层低孔低渗，侏罗系一白垩系“红层”组成区域盖层。思茅坳陷气水同喷、原油显示表明，该区海相地层仍有油气勘探前景，以存在K3-N区域盖层、断裂改造较弱、源岩成熟度较低、构造发育的英德一景谷、勐腊一勐满含油气保存单元为首选靶区，具有一定勘探前景。

| Abstract: | There are 2 covering strata of Proterozoic and Mesozoic - Cenozoic in Simao depression, which have many assemblages of genesis - reservation - covering such as the hydrocarbon - bearing formation mainly of Permian and Triassic, the reservoir with low porosity - seepage and the regional covering bed of Jurassic - Cretaceous ＂red - bed＂. In the Simao depression, the eruption of air together with water and the indication of raw oil show that there is still the exploration prospects of the marine facies bed in Simao depression. The Yingde - Jinggu, Mengla - Mengman oil - gas reservation unit with the regional covering bed K3 - N, weak fault - reformation, low maturity of original rock and the developed structure can be considered as the first target with a certain exploration prospect. |
