查询词典 sand

Based on the electric models for shaly sands and tuffaceous sands, this text derived modelsof saturation bored with water for the tuffaceous sands: Tuffaceous sand S-B Model andEffective Medium HB Model;The first supposed that the parts of shaly sands and thetuffaceous part were electric parallelly, and the other considered the electric rock matrix as sandmatrix, tuffaceous matrix and shaly matrix were parallel, and ignored the difference betweenwater bounded with shaly sand and water in the formation.

基于泥质砂岩的导电模型并结合凝灰质砂岩骨架导电的特点，建立凝灰质砂岩含水饱和度导电模型：凝灰质砂岩 S-B 模型和有效介质 HB 电阻率模型；前者假设凝灰质部分与泥质砂岩部分并联导电，而后者将凝灰质砂岩骨架导电看成砂岩骨架颗粒、凝灰质颗粒和泥质颗粒的并联导电，并忽略粘土结合水与地层水导电性的差异。
