塔里木盆地巴麦地区小海子组碳酸盐岩储集层特征与油气成藏

The reservoir characteristics of Xiaohaizi formation carbonate rocks were studied, the favorable reservoirs were evaluated by core; hydrocarbon charge and main factors controlling hydrocarbon accumulation were studied by the techniques of fluid inclusion. The results indicate that the main rock types of Xiaohaizi formation carbonate rocks are grainstone and dolomite. The reservoir types are pore, pore-fracture and fracture. The main factors influencing the reservoir ability are sediment, diagenesis and structure. The best reservoirs are located in Well Ba5, Bacan1, Mai4 and Qu1 area. The type of hydrocarbon reservoirs is mainly anticline reservoirs. There are at least two oil/gas charges in Bashituo anticline reservoirs, i. e., late Hercynian and late Himalayan. There are at least one oil/gas charge in Yasongdi anticline reservoirs, i. e., late Himalayan. The reservoir characteristics are the main factors controlling hydrocarbon accumulation, and structure evolvement, fault and trap are important factors controlling hydrocarbon accumulation.
