摘要
该文提出一种由计算机自动识别复杂岩性地层的方法。首先在储层各类地质模型基础上建立了诊断储层类型的物理特征参数模型;其次根据模式识别、专家系统技术建立了识别各类储层的判定系统;最后建立了划分储层序列的彩色绘图系统。该系统在大庆油田试验,取得了良好效果。
Reservoirs classification based on multi-well-logging information is mainlymade by manual interpretation, hence, the efficiency is low. This paper presents a method rec-ognizing the reservoirs of complicated rock with computer. Firstly, the model of phy-sicalfeature parameters diagnosing reservoirs is designed by means or the geological model ofdifferent kinds of reservoirs. Secondly, the identification system recognizing different kindsof reservoirs is designed with pattern recognition and expert system techniques, Finally, thecolour drawing system of the classified reservoirs is designed, The system introduced heredealed with Daqing oil-field's data and a good effect was attained.
