塔里木盆地塔中地区Ⅰ号断裂坡折带为碳酸盐岩油气藏的有利成藏区.由于受碳酸盐岩储集层特性的影响,其整体含油、局部富集的特征十分明显.从储层的沉积相、物性和类型三个方面分别讨论储层对油气总体分布的控制作用.认为生物骨架礁沉积区、储层物性高值区及裂缝-孔隙型储层发育区为目前高产油气井的主要分布区.

The Upper Ordovician carbonate reservoir in Tazhong-ⅠSlop-Break Zone of Tarim Basin is a favorable zone of hydrocarbon accumulation. The characteristics of the carbonate reservoir that obviously influence and control, in whole and local, on distribution of hydrocarbon in this zone is discussed from three aspects including depositional facies, physical properties and types of the reservoir. It is indicated that the sedimentary area of framework reefs, the area of high-valued physical properties and the development area of porous reservoirs are the main range of high oil and gas productivity wells.
