曲线融合技术在地层划分对比中的应用

The Application of Curve-integrated Technology in Stratigraphic Division and Correlation

介绍了基于统计加权的测井曲线融合技术原理、方法和步骤。以牛庄洼陷某工区为例,利用该方法计算了30多口井的融合曲线,结合区域地质背景及浊积砂体的沉积规律,对该区目的层段进行了沉积旋回划分和对比,取得较好的地质效果,由预测的浊积砂体的成功率大大提高。

The paper introduces the theory,method and steps in details for integrating logging curves based on statistical method.Sampling as a projection of Niuzhuang sag,the integrated curves of more than30wells are processed by using the method,and have been used in dividing and correlating the dedimentary cycle of the target zone with regarding as geology setting and sendimentary regularity,Application results shows the method can improve the correlation accuracy and predication of turbidite sand bodies.
