摘要:

摘要:微构造研究的核心问题就是井间目的层的深度预测。对小于15 m的薄层的井间深度预测,地震资料已无能为力,分形几何理论最适合于预测这类非均质储层的井间深度。主要内容包括:对目的层的深度进行趋势面分析;计算局部的分维数H[1];计算各点的残差;最后求得井间深度预测值。对DLJ油藏的井间深度进行预测,结果表明,效果很好。通过该方法绘制的微构造图能对剩余油的分布进行有效预测。

关键词: 分形学, 剩余油分布, 区域构造图, 非均质油藏

Abstract:

Prediction of depth between wells is a key issue in micros-structure study. The seismic data can not predict the depth of formation with a thickness of 15 meters or less, but the fractal theory can be successfully applies. The process to fulfill predicting parameter between wells include: trend surface analysis of the depth; calculation the fractional dimension H ; calculation of the residual error of every point and prediction of the value by trend value combining residual error. The result of predicting the thickness of DJL reservoir has verified the validity of the method. Drilling data indicates that’s microstructure map plotted with the method can effectively predict the distribution of residual oil.

Key words: fractal, distribution of residual oil, regional structural map, heterogeneous reservoir
