| 砂泥岩薄互层电阻率准确测量是提高泥质砂岩储层计算的一项重要工作。为了解决薄互层电阻率准确测量问题,本文提出一种三维感应成像测井仪的设计与实现方法。首先,基于感应电磁测量方法,设计由一个三轴发射器,四个单轴接收阵列和三个三轴的接收阵列组成的三维探测器。在此基础上,通过三维线圈系参数与结构创新设计、多频循环发射、高精度多道同步采集、高性能发射接收一体化集成等技术实现,在每一个深度点可获取78个电导率测量值。最后,利用数据校正与处理技术来消除各种环境影响,经过理论模型和实际资料的处理结果均证实,该仪器可有效提供传统阵列感应测井仪的所有不同探测深度、不同纵向分辨率的阵列电阻率曲线外,还可得到地层水平电阻率、垂直电阻率、地层倾角和方位角等地层信息参数,有效解决了砂泥岩薄互层电阻率准确测量难题。 |

| Accurate measurement of resistivity of sand-mudstone thin interaction layer is an important task in improving the calculation of argillaceous sandstone reservoirs. In order to solve the problem of accurate measurement of thin interaction layer resistivity, this paper proposes a design and implementation method of 3D induction imaging logging tool. First, based on the inductive electromagnetic measurement method, a 3D detector consisting of a three-axis emitter, four single-axis receiving arrays and three three-axis receiving arrays is designed. On this basis, through the 3D coil system parameters and structural innovation design, high-performance transmission and reception integration, multi-frequency cyclic transmission, high-precision multi-channel synchronous acquisition and other technologies, 78 conductivity measurements are available at each depth point. Finally, data correction and processing techniques are used to eliminate various environmental impacts, and the results of theoretical models and actual data are confirmed that in addition to effectively providing array resistivity curves for all different depths of detection and different longitudinal resolutions of conventional array induction logging tools, the instrument can also obtain formation information parameters such as formation horizontal resistivity, vertical resistivity, formation dip angle and azimuth angle, which effectively solves the problem of accurate measurement of resistivity of sand-mudstone thin interaction layer. |
