摘要
只有正确地了解地层的各向异性性质,才能在钻井过程中科学地利用这一特性。本文根据钻头与正交各向异性地层相互作用模型,导出了反演计算地层各向异性的物理模型。将该模型与下部钻具组合分析程序相结合,便可利用井史资料定量评估所钻地层的各向异性性质,评估方法简单易行,便于现场应用。
Only after obtaining the true data about formation anisotropy anisotropic drilling characteristics of the formation can be used scientifically in drilling operations.This paper presents a physical model for evaluating formation anisotropy, which is in the inverse mode of a rock-bit-formation interaction model .Combined with a BHA analysis program, this model can be used to esttimate formation anisotropy from field drilling data. Such a method of assessment can be readily used by field engineers.
