摘　　要：雅克拉断凸储层主要有碎屑岩和碳酸盐岩两大类。下古生界以碳酸盐岩为主，主要储集空间类型为裂缝－孔洞型，为好－ 很好的储集岩。下石炭统、中新生界以碎屑岩为主，下石炭统以东河砂岩中等偏好的储层为主，自西向东储集性能明显变差；中新生界储层则为中等－ 较好的储层，储集性能的好与差受沉积环境的影响。There are two kinds of reserviors consisting of clastics and carbonates in Yakela Black. Reser viors in the Lower Paleozoic are dominated by carbonate rocks with fracture as storing space, which are favorable for hydrocarbon accumulation. Clastic reserviors were developed in the Lower Carboniferous, Mesozoic and Cenozoic. Donghe sandstones in the Lower Carboniferous was fair reservior worsening east-toward. Quality of reserviors in the Mesozoic and Cenozoic was controlled by their sedimentary environments.
