【多选题】以下关于串联和并联导电模型的描述正确的是
A.
岩石成多层结构,若电阻率测量方向垂直于多层介质,则应采用串联导电模型
B.
岩石中存在裂缝,若裂缝方向与电阻率测量方向近似平行,应采用并联导电模型,将岩石基质和裂缝并联
C.
实际岩心内矿物、孔隙结构、流体分布等较复杂,难以直接用串并联模型表征,在实际应用中常以串、并联模型表征岩石电阻率的上下限
D.
泥质砂岩储层,若泥质主要以内衬式存在,应采用并联模型考虑地层水和泥质的导电性

【多选题】以下关于地层水电阻率的表述正确的有
A.
地层水导电能力是用单位时间内所搬运的离子数量来衡量的
B.
溶液含盐量越高,离子迁移速度越快,则溶液导电能力越强
C.
随温度升高,溶液中盐的溶解度增加,离子数目增多,溶液黏度降低,溶液电阻率降低
D.
无论含有什么盐类的地层水都可以换算成等效NaCl溶液
