摘　　要：本文详细介绍了斯伦贝谢推出的高清微电阻率成像仪——FMI-HD。该仪器是在工业标准的FMI设计基础上改进的,利用全新的电子线路及先进的并行处理技术,使得在在盐水泥浆或高阻储层条件下,图像的保真度和清晰度上大大提升。增强的并行信号处理和高分辨率模数转换等特点,明显地提高了仪器的信噪比,从而使图像清晰度增加了4倍。该仪器在8英寸井眼中,井壁覆盖率达80%,其垂向及方位分辨率为0.2英寸。高清晰度、高分辨率图像为地质、测井、油藏、岩石力学工程师提供了更为可靠的图像支持和解释依据。本文还介绍该仪器规格及其性能。The paper gives detail introduction about FMI-HD high-definition formation micro-imager developed by Schlumberger,which is built on the well-proven micro-resistivity of the industry standard FMI full bore formation micro-imager.It makes video fidelity and definition improve greatly in salt-saturated mud or high-resistivity reservoirs.Enhanced parallel signal processing and high-resolution analog-digital conversion improve the signal-to-noise ratio of the tool so that the image resolution increased four times.In 8in borehole,the sidewall coverage rate is 80%,and the vertical and the azimuth resolution is 0.2in.High-definition and high-resolution images provide more reliable images and interpretation basis for the geological,logging,reservoir,rock mechanic engineers.The paper also introduces the specification and performance of the tool.
