摘要
毛志强，朱卫红，汪如军．塔里木盆地油气层低阻成因实验研究（Ⅱ）．测井技术，１９９９，２３（６）：４０４～４１０对塔里木盆地塔北地区低阻油气层的实验数据进行了全面分析。根据实验数据，提出用后三点法确定Ｃｏ－ Ｃｗ 实验关系基本参数。数据分析表明，指数ｍ与温度及溶液矿化度无关。根据实验数据确定了阳离子当量电导Ｂ值与地层温度和溶液矿化度（或电阻率）关系图版。电阻率指数与含水饱和度实验结果证实了油层阳离子交换量随含水饱和度降低而增加的理论推断，指数ｎ与温度及溶液矿化度无相关关系。塔里木盆地塔北地区低阻油气层表现出了与Ｗａｘｍ ａｎ－Ｓｍ ｉｔｓ方程类似的规律，但阳离子当量电导Ｂ值这一重要参数与Ｗａｘｍ ａｎ 等人发表的结果又有一定差别。
This part of the paper presents the detailed data analysis of the experimental investigation on the genesis of low resistivity pay zone in northern region of Tarim Basin. A three point method is proposed to define the linear segment of C o- C w relation.The measurements show that both m and n are independent of the additional conductivity of clays and the equivalent cation exchange capacity of oil bearing zone increases as brine saturation decreases, which agrees well with what Waxman et al.concluded in seventies. The equivalent conductance of the counterions as a function of brine resistivity and temperature is determined based on lab measurements of ten samples at the conditions of four temperatures and six solution salinities.The data analysis demonstrates that Waxman and Smits formula can be well used to describe the samples resistivity properties.Since the equivalent conductance of the counterions is different from that Waxman and Thomas presented,it is believed that the equivalent conductance of the counterions is not independent of reservoir.
