Recognition Technology in Container Rock of Watered Extent While Drilling

Using the geochemical logging data,this paper illustrates the reflection, the basic principles, and the counting parameter methods of watered extent recognition technology in container rock while drilling from the angle of geochemistry. It introduces oil-drived effect, relative factor methods, and chromatographic combination characteristics to distinguish the technical methods of watered extent in container rock. It also discusses the existed problems as the distinction between watered layer and oil and water layers, anisotropic container rock in brief.
