【摘要】 电性特征、物性参数及孔隙结构参数与砂体储集性有较好的对应关系,所以能够利用物性参数、电性特征对砂岩的储集性分类评价。根据岩石的物性特征和岩石薄片鉴定资料确定的分类标准将该井区储层划分为:I(好),II(中等),III(差)三大类。由定北5井和定北6井实际资料分别得到各井岩心孔隙度与测井孔隙度关系,建立相应的测井标准以划分储层。得出区内Ⅰ类、Ⅱ类储集岩比较发育的层段为定北5井下石盒子组各段及山2段,定北6井盒2段、盒1段及山1段。更多还原

【Abstract】 With the better corresponding relation between rock resistivity、physical parameters and pore structure parameters and reservoir capabilities of sand,so those parameters can be used to classify and evaluate the reservoir.This passage use this corresponding relation and rock thin-section identification to confirm the relationship between core porosity and logging porosity of well-5 and well-6,and establish the relevant well logging criterion in order to divide the reservoir in the northern part of Dingbian: I(good),II(moderate),III(bad)..It is considered that type1 and type2 reservoirs are more development in lower Shihezi Formation and Shanxi-2 Member of well-5,Shihezi-2 Member、Shihezi-1 Member and Shanxi-1 Member of well-6.更多还原
