Abstract:

Based on core analysis （including physical properties, cast thin section and mercury penetration）, the characteristics of petrology, physical property and pore of Lower Ganchaigou Formation in Qie 12 structure of Kunbei fault zone are analyzed. Combined with the structure and sedimentary features, the influencing factors of reservoir properties are analyzed. The result shows that the reservoir rocks are of low textural maturity and compositional maturity, poor sorting, high content of shale and clayminerals, the reservoir property is poor, and that the pore throat is small with poor sorting and pore connectivity. It is concluded that sedimentary environment, clay mineral, clay matrix and tectonic movement are the main factors influencing the reservoir properties.

Key words: fracture, development and distribution, controlling factors, Shiwu Oilfield
