| 中文摘要: |
| 井中激电法是金属矿钻孔中的有效地球物理方法之一。本文基于双域激电仪研发成果，在井中开展双域激发极化法试验研究，从装置的功能、技术指标、装置布置和试验方法等多方面进行了详细阐述，并将试验结果与时域激电仪进行了对比，验证了双域激发极化法的可靠性。该双域激电仪通过一次观测即可同时测量频域激电和时域激电的全部参数，包括视相位 .S、视电阻率 ρS、视极化率 ηS、视幅散率 FS，视相散率 XS和自然电位 VSP共 6个电性参数，其具有抗干扰能力强、精度高等优势，可为双域激电法在井中找矿提供多物性参数及理论依据。 |

| Downhole induced polarization/resistivity method is one of the most effective geophysical methodsin the exploration of metallic deposits. Based on the research of dual-domain exciter, we conducted the experimen.tal study of dual-domain downhole induced polarization/resistivity method. The function, technical index, devicelayout and test method of the device are elaborated in detail. The test results are compared with the time domain ex.cimer, and IP instrument, which verifies the reliability of the dual domain IP method.The dual-domain IP instru.ment can measure all parameters of frequency domain ips and time domain ips simultaneously through one observa.tion, including apparent phase .S, apparent resistivity ρS, apparent polarizability ηS, apparent divergence FS, appar. ent divergence XS and Spontaneous potential VSP six parameters in total, and has the advantages of strong anti-interference ability and high precision, and provides multiple physical parameters and theoretical basis for the dual-domain IP prospecting in well.main IP method in mine, underground and borehole prospecting. |
