The Study of Auto Contrast Method on Sandstone Reservoir in Density Well Net

Because of the complexity and particularity,especially the result is more depend on the expert's experience.the calculate method which is based on the simplicity mathematical model and short of he expert's experience is hardly to have any effective in the practice which is more complexity.The coalescent method of artificial intelligence and signal manage in the correlation of reservoir use log curve has been put forward in this paper.Following the principle of "controlled by classification and correlation ".The system of correlation has been setup,which can identify "standard layer" first,and then on the basis of "standard layer",interpret the fault,last identify the layer.Through the application,this system has high precision and will become a useful tool in the study of geology.
