| 摘 要： | 玉门油田青西区块下白垩统泥质岩类和白云岩类储层具有裂缝、孔洞和孔隙的复杂储渗空间，其毛管压力曲线明显呈阶梯状形态特征。根据裂缝、孔洞和孔隙的毛管压力曲线特征，可分别计算裂缝孔隙度、孔洞孔隙度和岩石孔隙度，以及裂缝宽度、连通孔洞的孔喉直径和连通孔隙的孔喉直径。根据毛管压力曲线上各储渗段的发育情况，玉门油田青西区块储层可分为裂缝—孔隙型、裂缝型、裂缝—孔洞型及裂缝—孔洞孔隙型。最后提出了反映裂缝性储层孔隙结构特点的参数—连通系数。

| 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. |
