以油气藏形成的静态要素为基础、以各要素的动态演化过程为主线，通过生物标志化合物对比、烃源岩热演化、流体包裹体分析以及典型油气藏解剖，厘清了准噶尔盆地南缘卡因迪克地区油气来源、成藏过程，建立油气成藏模式。卡因迪克地区原油可分为3类，分别源自侏罗系煤系地层、古近系湖相泥岩以及二者混源，以侏罗系油源为主。该地区主要接受了2期油气充注，分别距今10～8 Ma和2 Ma左右，第二期充注包含第一期充注所形成古油藏的调整。卡因迪克地区砂层主要受北部物源控制，与南部连通性差，油气在侧向上主要通过区域性不整合运移，断层是沟通深部油源及古油藏调整的关键因素。在断裂和背斜的双重控制下，油气藏类型以断控-挤压型背斜油气藏为主，成藏主控因素为沟通烃源的断层，成藏模式为混源、垂向运移为主、2期成藏、晚期为主。

Based on the static elements for reservoir formation, taking the dynamic evolution process of the ele-ments as the main line, the comparison of biomarkers and the analyses of source rock thermal evolutions, fluid inclusions and typical reservoirs were made to study the hydrocarbon source and accumulation process in the Ka-yindike region in the southern Junggar Basin. A hydrocarbon accumulation model was established to guide hydro-carbon exploration. Crude oils in the Kayindike region were classified into 3 types, respectively, from the Jura-ssic coal series, the Paleogene lacustrine mudstones and the two mixed, and the Jurassic coal series were more contributive. There were 2 major charging periods, about 10-8 and 2 Ma, respectively, and the ancient reser-voirs charged in the 1st period adjusted during the 2nd period. The permeable sand series in the Kayindike region were controlled by the northern source materials, and were poorly connected with the south. Hydrocarbon migra-ted mainly along regional unconformities, and faults played important roles in communicating deep source rocks and ancient reservoirs. Controlled by faults and anticlines, the reservoirs were mainly fault-controlled and squeeze anticline type. The main controlling factor for hydrocarbon accumulation was the faults communicating source rocks. The hydrocarbon accumulation model was featured by mixed sources, vertical migration and 2 accumula-tion periods, among which the 2nd period was the major one.
