摘要(Abstract)：

在低渗透砂岩油藏中的天然或人工裂缝分析研究的基础上,描述了不同类型裂缝的特点,进而提出相应类型的数值模拟技术,其中包括低渗透砂岩油藏开启缝中应用双孔介质模拟技术、低渗透砂岩油藏闭合缝/人工缝中应用平面渗透率级差及过井人工裂缝反映天然裂缝的方向性非均质模拟技术;并对压裂井产能与人工裂缝(裂缝的长度、条数)的关系进行了分析,同时对压裂井产能模拟提出了合理的建议。
On the basis of the analysis of natural or artificial fracture of low permeable sandstone reservoir, characteristics of kinds of fracture are described; then corresponding reservoir numerical simulative technique is put forward, including; applying dual porosity dual permeability simulative technique to open fracture of low permeable sandstone fractured reservoir, and applying multiple of areal permeability technique or artificial fracture reflecting natural fracture technique to close/artificial fracture. At the same time the relationship between fracturing well and artificial fracture (length and number of the fracture) is discussed, then some reasonable suggestions about fracturing well's productivity are put forward.
