薄层砂体预测多年来一直是油田开发过程中困扰油田地质学家的一个主要问题。针对大庆榆树林油田薄层砂体的沉积特点，采用一种新的储层横向预测方法——聚—关分析法来对薄层砂体进行定量预测。该方法将地质、测井、地震、数学地质和计算机技术多学科相综合，并以榆树林油田树３２井区Ｙ１组为例，对其薄层砂体进行定量预测，经钻井验证，精度达８６．５％。 Prediction of thin-bedded sand bodies has been a major problem for oilfield geologists over the years for oilfield development. According to the sedimentary characteristics of thin sand body in Yushulin oil field of Daqing, a new reservoir lateral prediction method, poly-correlation analysis, is used to quantitatively predict the thin sand body. The method integrates multi-disciplines of geology, logging, earthquakes, mathematical geology and computer technology. Taking the Y1 group of Shu-32 well in Yushulin Oilfield as an example, the method makes a quantitative prediction of the thin sand body. After drilling verification, the accuracy 86.5%.
