【Abstract】 The focused circuit of the dual laterolog tool is the key to controling the dual laterolog tool to meet electric field condition concerning the well logging. It not only decides accuracy of measurement of the tool,but also affects the differential character value between depth and shallow measurement. The paper discusses analog focusing models about the dual laterolog tool and provides the correlation results of the several focusing programs for reference to model selection and design of the tools.更多还原
