摘要
基于大量泥质砂岩岩心实验数据,探讨了Clavier与Waxman等关于W-S模型与双水模型描述泥质砂岩导电能力以及胶结指数是否受阳离子附加导电影响的争论。与双水模型相比,W-S模型能更好描述泥质砂岩的导电规律;双水模型在低温、低地层水溶液矿化度以及高温、高地层水溶液矿化度时,描述泥质砂岩导电的能力相对较差;与双水模型中胶结指数(mo)相比,W-S模型中胶结指数(m*)不受岩石阳离子附加导电的影响,而是受控于岩石的孔隙结构。
Based on the study of a large number of argillaceous sandstone core data,this paper discusses the debate between Clavier and Waxman for the W S model and the dual-water model:whether the conductivity of the argillaceous sandstone and the cementation index are affected by the additional conductivity of the cation.The study found that compared with the dual-water model,the W S model can better describe the conductivity of argillaceous sandstones.In addition,under the conditions of low temperature and low formation water salinity or high-temperature and high-layer water salinity,the dual-water model cannot describe the conductivity of argillaceous sandstone very well;compared with the cementation index(mo)in the dual-water model,the cementation index(m*)in the W S model is not affected by the additional conductivity of the rock cation,but is controlled by the pore structure.
