摘要
The hydrocarbon distribution and enrichment in marine carbonate reservoirs of the Cambro-Ordovician in Tarim Basin were found along the pre-Carboniferous paleo-uplift slopes, which are different from the overlying clastic rocks. In three big pre-Carboniferous paleo-uplifts in Tabei, Tazhong and Taxinan existed wide-gentle slopes with long-term stable development forms the geologic conditions of large-area hydrocarbon accumulations in these areas. These slopes can not only be the favorable positions of high-energy facies belts in the margin of platform, but also being suitable for the development and preservation of weathering crust-type reservoirs.
