Abstract: There are three kinds of reservoir space in clay stone and dolostone in lower Cretaceous at Qingxi areas, Yumen oil field: fracture, vug and pore, and the characteristics of capillary pressure curve like a ladder. According to the characteristics of the fracture, vug and pore on the capillary curve, the fracture porosity, vug porosity, pore porosity, the wide of fracture, throat diameter of vug and pore can be calculated. Reservoir can be classified on the bases of every section of reservoir space on the capillary curve. At last, connecting factor is put forward, which can fully reflect the pore texture characteristics of fracture reservoir.

Key words: fracture, vug, capillary pressure curve, connecting factor, reservoir, Yumen oil field
