摘　　要：针对油气勘探开发对随钻电阻率探测的实际需求和国产随钻电阻率仪器装备自主研发的迫切需要,本文对随钻电阻率多深度天线系结构开展了研究,提出了一种补偿式的多深度多频率的随钻电阻率天线系结构设计方案。基于数值模拟方法对仪器探测特性进行了考察及参数优化,该设计可实现多种深度的井下地层电阻率测量,同时能进行对称性电阻率补偿测量,消除井眼和工况影响。基于不同源距和不同频率测量组合,可提供更为丰富、准确的地层电阻率信息;同时也具有较好的地层纵向分辨率,对薄互层具有较高的探测能力。本研究对我国随钻电阻率仪器的自主研发具有一定参考价值,对我国复杂地层尤其是薄互层的油气资源开发也具有现实意义。In response to the pressing demand for resistivity detection while drilling in oil and gas exploration and development,as well as the urgent need for independent research and development of domestic resistivity-while-drilling tool,this study investigates the structure of a multi-depth resistivity while drilling antenna array.A design scheme for a compensatory multi-depth and multi-frequency resistivity-while-drilling antenna structure is proposed.Utilizing numerical simulation methods,the detection characteristics of the tool are investigated and parameters are optimized.This design enabled formation resistivity measurements at various depths while also facilitating symmetrical resistivity compensation measurements to mitigate the adverse effects of borehole and working conditions.By employing different source spacing and frequency measurement combinations,it provides more abundant and accurate information on formation resistivity.Additionally,it also has a good vertical resolution regarding formations and high detection capability for thin bed and thin interbed.This study has certain reference value for the independent research and development of the resistivity logging tool while drilling in China,and it also has important practical significance for the development of oil and gas resources in complex formations,especially in thin interbed.
