鄂尔多斯盆地西部延长组长8- 长10油组沉积测井响应特征

鄂尔多斯盆地晚三叠世时沉积构造活动较弱，水动力作用比较强。不同沉积环境具有不同的水动力特点，各种沉积环境的水动力条件，既控制着岩性、粒度、分选性、泥质含量的变化，同时也控制着岩石导电性、自然电位、自然放射性、声波传导特性等物理性质的变化，不同沉积环境形成的层序序列以及岩性变化常常具有各种测井曲线形态，测井曲线正是岩石各种物理性质沿井孔深度变化的物理响应。

The western Yangchang formation chang8- chang10 member sedimentary log response characteristic,Ordos basin

Late Triassic sedimentary tectonic activity is weak in Ordos basin,the hydrodynamic force function is quite strong.The different environment of deposition has the different hydrodynamic force characteristic,each kind of environment of deposition hydrodynamic force condition,is also controlling the lithological character,the granularity,the shale content change,simultaneously is also controlling the rock electrical conductivity,natural potential,natural radioactivity,sound wave conduction characteristic the ...
