微电阻率成像测井的特点是利用密集组合的电传感器,测量井壁附近地层的电导率,并进行高密度采样和高分辨率成像处理,提供一个类似岩心表面成像的井壁图像。地层微电阻率成像测井,在井旁构造研究、沉积特征分析、裂缝识别和岩石结构分析等方面具有独特优势。所形成的高分辨率井壁图像,不仅是钻井取心的重要补充手段,而且能提供更完整的信息。在松南气田营城组火山岩储层评价中,发挥了极其重要的作用。
Micro-resistivity imaging logging features the use of densely-combined electrical sensors to measure the electrical conductivity of the formation near the borehole wall, and high-density sampling and high-resolution imaging to provide a borehole image similar to core surface imaging. The formation micro-resistivity imaging logging has unique advantages in well-side study, sedimentary characteristics analysis, fracture identification and rock structure analysis. The resulting high resolution borehole image is not only an important complement to drilling coring but also provides more complete information. In Songnan gas field Yingcheng volcanic reservoir evaluation, played an extremely important role.
