Abstract：The annual task in 2013： the key factors of controlling the accumulation of deep oil and gas as well as the mechanism. Doing some following research： the intergrowth and association of the deep structural crack， corrosion pores and many types of reservoir space； the compositely additive effect and genetic connection of geological process such as the effect of hydrothermal fluid and Karstification； the Geological and geophysical response of deep carbonate reservoir space； In addition， the other issues relating with accumulation research and deep oil and gas. Accomplished mian works： ① deep research on the geological structure， restoration of tectonic tress field and paleostructure， and reconstruction of paleopressure and paleotemperature in the region of the North Tarim Uplift and the hinterland of Junggar Basin etc.②To further elucidate the hydrocarbon accumulation threshold， studying the characteristics of source rocks in different abundances of carbonate； revealing main accumulation and phase state characteristic and forming mechanism in the Tarim Basin， having builded enrichment mode of carbonate rock reservoir.③the main research are the controlling factors of carbonate fracture， reservoir type ，the prediction of favorable zone and the relationship of thermal fluid and reservoir. At the same time， inversion techniques being used to build a carbonate reservoir model， in order to carve fracture cave and pore system in carbonate reservoir. ④ the cretaceous deposition， evolution of reservoir and pore have studied as well as features and evaluation of Permian clastic rock reservoir and effective reservoir geophysical prediction method. ⑤Deep typical gas reservoirs in the Tarim Basin is analysised， and reservoir pattern is established ；the critical physical conditions of forming period reservoir about compact sandstone gas is determined；at the same time， the influence of conducting layer heterogenelty， sedimentary rock heterogeneity and continental reservoir hetergeneity in oil-gas migration and accumulation are studied； The relationships between distribution of oil-gas and fracture in characteristic area are concluded； ⑥Based on the analysis of forming mechanism and distribution characteristics of the Tarim Basin oil and gas.

Key word：Main factors of hydrocarbon accumulaiton；reservoir property；geological transformation；seismic inversion；hydrocarbon accumulaiton model
