岩性反演是岩性储层预测的主要技术,测井约束岩性反演就是把测井资料所具有的高的纵向分辨率特征和地震资料所具有的横向上可以连续追踪地层的特征结合起来开展储层预测,以达到识别目的层岩性的目的。主要从测井资料处理技术、储层精细标定技术、特征曲线重构技术和初始模型建立技术4个方面分析了如何做好测井约束的岩性反演。

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. 
