| 摘 要： | 库车坳陷大北-克深地区白垩系-古近系砂岩储层埋深一般大于5000m,压实作用强烈,微裂缝比较发育。大量研究表明,微裂缝的发育主要与埋深和砂岩的原始组构有关,微裂缝的发育在一定程度上提高了储层基质的渗透性。系统统计了砂岩储层微裂缝的面密度,对影响其发育的相关因素进行了分析,建立起微裂缝发育的多元线性回归模型,模型通过了显著性检验,可以用来对工区微裂缝的发育程度进行预测。

| Abstract: | The depth of E-K sandstone reservoir in Dabei–Keshen area of Kuqa depression is generally more than 5000 meters with intense compaction,and micro-fracture is strongly developing.Mass of research indicates that development of micro-fracture is mainly associated with depth and sandstone original texture,and the micro-fracture,to a certain extent,improves the permeability of reservoir matrix.In the paper statistics is conducted systematically of the surface density of sandstone reservoir;related factors that influence the development of micro-fracture are analyzed.The multiple linear regression model of micro-fracture is established.And the model was put through the test,which can be used to predict the area of micro-fracture development. |
