Application of Log Reconstruction Technique in Volcanic Reservoir Prediction
Zhu Chao, Cui Junfeng · Journal of Oil and Gas Technology · 2010
Volcanic reservoir had a stronger heterogeneity,conventional sonic log constrained inversion was usually influenced by many uncertain factors,therefore it could not be used to effectively reflect the characters of volcanic reservoirs.In allusion to the peculiar volcanic lithology,shallow and deep dual laterolog was used to reconstruct sonic logging curve.On the basis stated by means of BP neural network reversion,the distribution of volcanic reservoirs in Honghaoershute Sag of Erlian Basin is predicted and good effect is obtained.
