面向地质导向应用的前导模拟技术研究

On the Forward Modeling for Geosteering.

前导模拟技术属地质导向技术范畴内的核心技术之一 ,它由地层模型处理部分、沿井身轨迹曲线的随钻测井曲线正演部分、实时钻井时的实际与模拟曲线对比及反演部分组成。该文提出了在地层模型处理的基础上 ,进行仪器响应的数学归结 ,进而进行算法研究及面向地质导向应用软件实现的研究方法和思路。这对目前国内石油勘探开发行业前导模拟技术的研究具有指导意义。

Forward modeling is a core technology of geosteering.It consists of stratigraphic model processing,resistivity/gamma forward modeling along well trajectory,real-time geological correlation between measured curves and modeling curves while drilling as well as logging inversion.After illustrating stratigraphic model processing method,this paper gives LWD tool response’s mathematic description,arithmetic,software global design and points out the developing direction of forward modeling technology in China’s petroleum exploration and exploitation field.
