Interpretation model of general log-curves to volcanic reservoir properties in Changling No.1 gas field

Up to now,the research of general log-curves interpreting volcanic reservoir properties is little,and there is nofixed pattern to follow,and also no ready made formula. By using of BP neural network,the paper interpreted the nonlinear relationship between volcanic reservoir physical parameters and conventional log curve. The application of thismethod interprets the volcanic rock reservoir single well physical parameters in Changling No. 1 gas field Yingcheng formation. The model validation test has been shown withhigh accuracy and satisfactory result.
