测井资料在预测地层参数剖面方面的应用

钻井剖面上岩层的各种理化、力学及其岩石可钻性参数剖面对指导钻井工程的正常进行起到了非常重要的作用。提出了一种简单、适用且易于在计算机上通过计算机程序实现的方法，即根据岩石试验所得不连续且非等间距的理化、力学及其岩石可钻性参数，借助于传统的数理统计理论和新兴的灰色理论知识相结合的综合预测技术，把剖面上不连续且非等间距的理化、力学及其岩石可钻性参数通过连续变化并能反映所测岩层各种性质的测井资料，拟合出反映钻井剖面上岩层连续变化的各种理化、力学等岩石可钻性参数剖面。

PREDICTION OF FORMATION PARAMETER PROFILE WITH CONTINUOUSLY PROCESSING LOGGING DATA

Many formation parameters in the drilling section,including the physical and chemical parameters,mechanics parameters and rock drillability parameters are playing an important role in instructing drilling engineering.A simple and useful method which is easy to carry out the computing is given.The method uses the discontinuity and different interval parameters that are the physical and chemical parameters,mechanics parameters and rock drillability parameters which come from rock experiment,by means of the integrated prediction technology which is based on the traditional statistic theory and burgeoning grey theory,and then,the logging information of the whole well is combined and the above parameters of the whole well section synthesized.
