河流相沉积砂体预测方法研究
|
摘要
介绍一种河流相沉积砂体预测方法。该方法利用测井和过井地震资料标定砂体沉积类型、岩性组合、沉积结构、沉积构造和砂体宽度等特征。在此基础上 ,找出砂体宽度与其各种沉积特征之间地质规律 ,回归计算砂体宽度关系式。根据建立的关系 ,通过从砂体延伸方向和宽度预测砂体的形态空间分布。
Introduced is a method for predicting sedimental sand body with fluvial facies. Log data and crosswell seismic data are used to calibrate the sedimentation types of sand body, lithological composition, sedimentary structure and sand body width, etc., on the basis of which obtained is the relationship between the width and various sedimentary features of sand body. Then, prediction of the shape and spacial distribution is made from the width and the extension direction of sand body.
