本刊发表过许多有关低阻产层和怎样利用常规电缆测井识别和评价低阻产层的文章。长期以来,人们一直认为水——能自由流动的水或束缚在孔隙表面的水——的总量是电阻率测量的一个控制因素。迄今为止,还没有能够区分这两种水的电缆测井工具。要想使测井解释始终与油井实际生产结果一致,那么这种区分就是必不可少的。
The journal has published numerous articles on low-resistivity production and how to identify and evaluate low-resistivity production using conventional cable logging. It has long been believed that the total amount of water-free-flowing water or water bound to the pore surface-is a controlling factor in resistivity measurements. To date, there are no cable logging tools that can distinguish between these two types of water. This distinction is essential if logging interpretation is to be consistent with actual well production.
