摘要
成功地解决了由双侧向测井深、浅视电阻率同时反演地层真电阻率和等效侵入带直径问题,建立了可靠的反演算法,此算法的最主要优点在于它不依赖于初值的选取,因而是真正具有工程实用价值的算法。经过优化后的算法和程序具有很高的精度和较高的计算速度,完全符合测井解释的要求.
In this paper, we establish a method to determine the resitivities of the earth and diameter of invaded zone simutaneously,using the deep and shallow apparent resitivitics,and propose a new algorithm. The main advantages of our method is that the selection of the initial value is need not, but in proviously work, it is nescssary and it must close to real values. Thus our algorithm has the real worth in the engencering. A Numerical inversion show it is rcliabe and robust.
