| 1. | The curvatures of the curves between total formation conductivity c , and total water saturation swt , are greatly affected by formation matrix conductivity cma , while it is less affected by clay conductivity ccl . the curvatures of the curves between c , and swt are only affected by w , a factor number that is related to relative volume of water content in the formation , while is not much affected by the matrix factor number ma . when ct is kept to be constant , swt increases ash ma increases , and decreases as w increases 通过对该模型的影响因素分析,发现泥质分布形式对模型计算的含水饱和度有很大影响;随cma变化, ct与swt关系曲线的曲率发生变化;随ccl变化, ct与swt关系曲线的曲率基本不变;只有或_ w变化, ct与swt关系曲线的曲率发生变化;只有_ ( ma )变化, ct与swt关系曲线的曲率相近; ct一定, swt随或_ ( ma )增大而增大,随_ w增大而减小。 |
