In this paper we propose an automatic sedimentary facies identifying method based on combing fuzzy ellipsoidal neural networks and image process technology. First, we translate digital well measure curves and stratum parameters into binary image modes. Second, through contracting binary data codes, we distill and store stratum mode characters token from well measure curves. Last, we combine fuzzy ellipsoidal neural networks clustering and BP algorithm to train a multi-layers forward neural network. The neural network keeps properties of being stable, fast learning, awfully memorable and generalized ability. This model is suitable to solve issues of sedimentary facies identify. The test result shows this special method can identify sedimentary facies very well.
