W-S模型与双水模型对泥质砂岩附加导电性描述的对比分析
Comparison of W-S Model and Dual Water Model in Describing the Additional Conductivity of Argillaceous Sandstone
摘要
Abstract
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 hightemperature 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.关键词
