【摘要】 常规双侧向测井仪因其良好的聚焦性能而得到广泛应用 ,虽然它的径向探测深度较深但对薄层的分辨能力却较差。适当修改现有双侧向测井仪电极系 ,通过不同地层模型条件下的模拟计算和伪几何因子考查 ,结果表明 ,该电极结构垂直分辨率有了很大改善 ,受井眼的影响较小 ,径向探测深度也较深。更多还原

【Abstract】 The conventional dual laterolog tool is widely applied to oilfield with its better focusing performance. Although its radial investigation depth is deeper, its performance to detect thin layer is worse. The modification of the electrodes of current laterolog tool and the computations of logs and pseudo-geometric factors in various formation models manifest that the configuration of the electrodes has better vertical resolution, less borehole effect and deeper radial investigation depth.更多还原
