摘要
通过对测井原理、水淹层解释、大孔道形成机理的研究,总结大孔道形成后在测井曲线上的响应特征,并利用层次分析原理对各个因素综合分析,提出1个准确合理的综合参数,最终实现人机交互式识别大孔道,称之为大孔道参数法。将其应用到大庆喇嘛甸油田大孔道判别中,取得令人满意的结果,正确率达80%以上。结果表明:大孔道参数法识别大孔道是行之有效的。
Through studying the well logging principle, the interpretation of water-out zones, and the formation mechanism of the large pore path, we find the logging response characteristics when there are large pore paths. On the basis of a comprehensive analysis of various factors made by using the Analytic Hierarchy Process, a comprehensive parameter is proposed and the identification of large pore paths is achieved through mancomputer interaction. The method is thus named the parameter method for large pore paths, which has been implemented successfully in Lamadian Oilfield with a precision of over 80 %.
