等权共振法在油页岩区“甜点”预测中的应用

Application of Equal-Weight Resonance Method for “Sweet Spot” Prediction in Oil Shale Area

摘要: 油页岩区“甜点”一般分工程“甜点”与地质“甜点”，又称之为双“甜点”。五维数据的出现，使“甜点”的预测更多元化。预测“甜点”的目的是提高钻井的采收率，使每口钻井更具有效益化。过去各种“甜点”预测结果以多种图形式或叠合形式(该形式的弱点不能叠合过多图件)提供给决策者参考，多种图形式不能将最有利的区域更直观地展现出来，叠合的形式如果效果不好反而影响决策者的判断。那么如何使更多的信息能综合表现出来，等权共振法使各种“甜点”信息综合在一起，总体表现在一张图中，决策者可以一目了然。

Abstract: The “dessert” in the oil shale area generally includes engineering “dessert” and geological “des-sert”, also called double “dessert”. The emergence of five-dimensional data makes the prediction of the “dessert” more diversified. The purpose of predicting the “dessert” is to increase the recovery rate of drilling and make each well more profitable. In the past, various “desserts” prediction results were provided to decision makers in multiple graph forms or superimposed forms (the weaknesses of this form cannot be superimposed on too many graphs), and the areas where multiple graph forms cannot be the most advantageous are more intuitively displayed. So how to make more information can be comprehensively displayed? The equal-weight resonance method integrates all kinds of “dessert” information together, and the overall performance is shown in a picture, so that decision makers can see it at a glance.
