鄂尔多斯盆地樊学王盘山地区延长组长4+5储层有利区预测

Prediction of Favorable Area of Chang 4+5 Reservoir of Yangchang Formation in Fanxue WangPanshan Area in Ordos Basin

为寻找鄂尔多斯盆地樊学王盘山地区延长组长4+5油层组有利储层,应用地质、岩芯及测井资料,开展了小层划分对比,建立了测井相识别模式,编制了小层沉积相平面展布图,进而研究了沉积演化规律、储层砂体展布及物性分布规律。在此基础上,应用聚类分析方法对储层进行了评价与分类、储层有利区预测,为樊学王盘山地区长4+5油层组下一步的勘探开发提供了理论指导。

In order to find the favorable reservoir of Chang 4＋5 in Wang Panshan area in Ordos basin,based on data of geology, core and logging, the stratigraphic division and correlation were carried out, the recognition pattern of log facies and plane distribution of sedimentary facies were established, and then the evolution law of sedimentary facies, the exhibition regular of reservoir sand and physical property were studied. On the basis of researches mentioned, the evaluation, classification, and favorable area prediction of formation were implemented with the clustering method, which could provide theoretical direction for reasonable exploratory development of Chang 4＋5 formation in Wang Panshan area in the future.
