Numerical Analysis of Logging Responses for Dual Laterolog Resistivity Logging-while-drilling Tool
摘要
Abstract
A new LWD electrode-current resistivity logging tool,i.e.,Dual Laterolog Resistivity Logging-while-drilling tool (DLR) has been developed and has begun to be tested in oilfields.DLR can provide deep & shallow resistivity curves,used for identifying mud invasion and formation evaluation during drilling high angle and horizontal wells.This paper presents the DLR's electrode array,measurement principle,tool constant and response characteristics of borehole effect,vertical resolution,invasion by 2D and 3D numerical modeling.Compared with the other LWD laterolog resistivity tools,the numerical results show that DLR has a deeper DOI,betterresolutionandlessboreholeeffect.关键词
