摘要
在测井曲线井间对比中,用寻优追踪法将多种测井信息加以最优组合,不但能消除动态规划算法的维数障碍,而且能更有效地克服测井信息间的相关性和互逆性,突出可对比因素,能提高用有序元素最佳匹配法进行地层对比的可靠性。
In the correlation of well log from well to well, the best combination of various log data can be achieved by using the method of optimal pursue, which can overcome the relationship and internegativity of log data between wells more effeciently than weight dedimension and principle component analysis, and eliminate the dimension obstacle of dynamic programming algorithm. Furthermore, it can spotlight the correlatable factors, and enhance the reliability of formation correlation by using difinite element optimal match method.
