Oil-water Layer Interpreting Methods in Series of Deep Strata in Xia'ermen Oilfield
Zhai Zhong, Qinghong Zhang · Journal of Jianghan Petroleum Institute · 2003
In consideration of reservoir properties and complicated geologic characteristics of series of deep strata in Xia'ermen Oilfield, geologic factors of oil-water relationships of the deep strata series in the oilfield are analyzed, a method for interpreting the oil-water layer is established on the basis of studying reservoir lithologics and its physical properties, and electrical properties and oil-bearing relation. Methods of pattern recognition of oil-water layer and neural network pattern recognition are introduced based on conventional chartboard method, well logging precision in oil-gas reservoirs are raised greatly by combining these 3 methods.
