Abstract: The low permeability sandstone reservoir has become an important exploration target, but the variety of micro-pore structure makes the logging response characteristics difficult to reflect reservoir features clearly. The data of mercury injection, nuclear magnetic resonance (NMR), physical properties, thin sections and CT were used to analyze the pore structure of low permeability beach bar sandstone of the fourth member of Shahejie Formation (Es4) in southern slope of Dongying Sag. The pore structure were divided into three types and five subtypes:typeⅠ (Ⅰ1 and Ⅰ2), type II (Ⅱ1 and Ⅱ2)and type Ⅲ. The pore structure type is controlled by mineral content, grain size and diagenesis. The volume and features of micropores (pore throat radius less than 0.024 8 μm) are important factors that cause the differences of pore structure types. The relationships among micropore volume, mineral content, grain size and electric properties were analyzed. It is found that mineral content and grain size affect micropore volume and features. In addition, the micropore volume is closely related to the electric properties. Logging curves are sensitive to the change of micropore volume, so it is helpful for dividing pore structure type in wellbore and identifying effective reservoirs.

Key words: tight sandstone gas, geologic characteristics, water saturation, pressure system, adsorbed gas, Sulige Gasfield, Ordos Basin
