| 摘 要： | 柴达木盆地西部油气资源十分丰富，但由于油气成藏条件复杂，油气成藏的主控因素尚未探明，因此探明率非常低。研究表明，柴达木盆地西部地区油气藏的形成主要受控于喜山晚期构造；有效烃源岩及优质烃源岩发育的次级生烃凹陷控制了油气分布范围；古构造或古斜坡是主要油气富集区；新构造运动期形成的断裂体系及其储、盖组合控制了油气纵向展布位置。油气成藏主控因素及富集规律的认识为该区油气勘探提供了理论支撑，指明近期油气勘探方向，并在油气勘探中取得了明显的效果，近年来控制油气地质储量1亿吨，新增探明油气储量4 000万吨。

| Abstract: | As study proved, the oil and gas accumulation in the western Qaidam was mainly controlled by the late Himalayan tectonic events, and the effective source rocks led to oil and gas distributed around the five main hydrocarbon generation centers or along the relative nearby slope zones. The paleo structures and those structures with paleo tectonic situation were the major areas of hydrocarbon accumulation, and fault systems and their combinations with reservoirs controlled the lateral and longitudinal distribution of oil and gas. These conclusions on hydrocarbon distribution regularities establish the theoretical foundation for the future petroleum exploration, and imply the exploration directions for recent petroleum exploration. |
