Abstract: Chang 3 reservoir of Yanchang Formation in Ordos Basin is similar to other reservoirs, but the reserves are the least. The data of cores, well logging, mud logging, oil testing and test mining in Xiasiwan Oilfield were applied to study the development characteristics and controlling factors of hydrocarbon accumulation of Chang 3 reservoir. The results show that the structure of Chang 3 reservoir in Xiasiwan Oilfield is relatively gentle and develops a EW-trending nose-shape structure. It belongs to delta plain subfacies, and its microfacies include branch channel, onshore natural dike, crevasse fan and marsh. Sand body is mostly developed in the branch channel microfacies. Reservoir lithology is dominated by fine-grained feldspathic sandstones, and the main pore type is intergranular pores. The average porosity is 12.4%, and the average permeability is 1.28 mD, with lowporosity and low-permeability. The reservoir is mainly controlled by lithology, followed by structural factors, which belongs to structural-lithologic reservoirs. The research results have a guiding role for oil and gas exploration in Chang 3 reservoir.

Key words: sedimentary facies, reservoir characteristics, reservoir-control mechanism, Chang 3 reservoir, Ordos Basin
