摘　　要：高楚桥等．ＥＬＡＮ解释（程序）方法简析．测井技术，１９９５，１９（２）：１３５～１３９ＥＬＡＮ程序的目的是求解组成地层的每个矿物和流体的体积。它既能处理裸眼井测井资料，又能处理套管井测井资料，能用多个模型并行处理，然后对各模型的结果进行组合，求得一个最可信的结果。程序既可采用线性算法，又可采用非线性算法。当所用方程全为线性方程时，采用线性算法。用线性算法时的速度要比用非线性算法的速度快２～１０倍。组合模型的方法有三种：内部概率法、外部概率法及人工拼接法。程序可用两个参数检查解释结果的质量：理论测井曲线的标准偏差及分辨率数。The purpose of ELAN program is to determine the volume of each mineral andfluid in the formation.It can be used for both cased hole and open hole interpretation.Parallel processing can be made with multiple models.The final answer whichis the most believable one is obtained by combining the answers from the differentmodels.The program may invoke either the linear solver or the nonlinear solver fora model.If all the response equations for a model are linear,the program will invoke the linear solver for that model.The linear solver runs 2～10 times faster thanthe nonlinear solver.There are three methods to combine models:internal probability,external probability and splicing methods.Two parameters are used to checkthe quality of the outputs:one is the standard deviation between the actual log andthe reconstructed one,the other is resolution.
