ANALYSIS ON KEY TECHNIQUES OF LOG CONSTRAINED LITHOLOGICAL INVERSION
测井约束岩性反演关键技术分析

Lithological inversion is a key technique to predict lithological reservoir,log constrained lithological inversion aims at predicting reservoir and identifying lithology of target bed by integrating high vertical resolution and continuous tracing stratigraphic information of lateral seismic data together.This article makes an analysis on constrained lithological inversion focusing on the following 4 techniques: well log data processing,reservoir fine calibration,characteristics curve reconstruction and initial model constructing.
