In order to study oil-gas accumulation law in Fangzheng fault depression, based on the characteristics of development and distribution of source rock and caprock, this paper studied the spatial matching relation between source rock and caprock and its control action on oil-gas accumulation in Fangzheng fault depression. The result shows that there are two types of spatial matching relation between source rock and caprock itself and lower sourcerock and upper caprock in Fangzheng fault depression. There are two sets of spatial matching relation between source rock and caprock in the first type, and they formed in Xin’ancun-Wuyun Formation. There are three sets of spatial matching relation between source rock and caprock in the second type, and they formed in Xin’ancun-Wuyun Formation to the second member of Baoquanling Formation. The first and third sets distributed in the whole fault depression, the second and fifth sets only distributed in the eastern fault depression, and the fourth set only distributed in the western fault depression. The control action of these five sets of spatial matching relation between source rock and caprock on oil-gas accumulation mainly displays in the following three aspects: ①the numbers of spatial matching relation between source rock and caprock control oil-gas accumulation and distribution horizons; ②the numbers of spatial matching relation between source rock and caprock in the same horizon control oil-gas accumulation amount; ③caprock quality in spatial matching relation between source rock and caprock also controls oil-gas accumulation amount.
