摘　　要：为了满足大庆外围低渗透油田的勘探开发和吉林油田厚层细分,设计了SHDL-1高分辨率双侧向(0.2 m)则井仪器,该仪器是WISEYE1000测井系统高分辨率测井系列的主要方法之一。电极系的优化设计在保证仪器纵向分辨率和径向探测深度的前提下,力求具有理想的测量范围和井眼环境适应能力;数字聚焦、数字滤波、相关处哩技术的应用提高了仪器的稳定性和测量精度;模式供电系统的独特设计保证3种数字聚焦模式既能同时独立工作,又能克服电极间的分流影响,提高了测量电阻率的准确性。High Resolution Dual Laterolog Tool （0. 2 meter） is to meet the exploration and development for Daqing peripheral low permeability oilfield and Jilin oil field latilamina splitting so that a high precision and high resolution logging tool is designed, which is also one of the methods for 0. 2 meter high resolution series of VISAI1000 logging system. To guarantee vertical resolution and radial depth of investigation for instrument, we try to optimize the design of electrode to have the ideal range of measurement and borehole environment adaptability. Application of digital focusing and digital filtering and related processing technology has improved the stability of the tool and measurement accuracy. The unique design for mode electric power system can guarantee the three digital focusing modes that is not only able to work independently, but also overcome the shunt effect and improve the measuring resistivity accuracy.
