摘要:
本软件系统是1993年6月为中国吉林油田研究开发完成的研究项目。本系统可在油田开发区充分研究若干勘探钻孔的岩心、测井资料和地震剖面资料等基础上,建立互相关的地区性岩性和沉积微相模式,通过试验,选择最佳判别模式,再用数字化的测井资料判别每一口井的地下地质情况,建成各类数据库,用以绘成任何钻孔和任何层段的岩性柱状图和微相演化图。再用地震资料补白没有钻孔地区的地下地质情况,生成各砂组的岩性、微相和优势微相数据库。能绘制出任何砂组或层段的各种岩性厚度或各种比值等值线图、优势微相分布图、岩性的或微相的栅状对比图等,还有对应的油层物性柱状图和平面图。除二维图形外,亦可制作三维图形和各种叠加图形。
Abstract:
This software is composed of a series of discriminant models based on the detailed compari-son studies between the sedimentological features of cores and the geophysical characteristics of well loggings and seismic sections. Containing 3 parts i.e. basic sedimetological program,well log processing program and seismic processing program,the software has been successfully used to predict the oil/gas traps in Yingtai oil field of the Songliao Basin(NE China,Cretaceous)by the systermatic mapping of sedimentary microfacies and the detailed lateral correlation of thin bedded reservoir sand bodies.
