摘　　要：高密度电阻率法测量道数多,工作效率高,但是受排列长度的限制,勘探深度较浅。在海南岛西南部裂隙型地热资源勘查评价中,使用遥控电极阵列新技术。在排列的两端延长地段,增加A、B导线和电极阵列,进行常规装置和任意极距测深观测,所得数据合并反演,勘探深度达到常规装置的三倍。取得良好地质效果,具有进一步完善、推广应用的价值。It can be seen that electrical resistivity imaging method, with high efficiency and multiple measuring lines, has shallow sur- veying depth limited by array length. The combination of arbitrary pole pitch sounding and telecontrol electrode array method placing two wires A, B and telecontrol electrode array at the ends of array can triple the conventional measurement length through data merging and inverting in the prospecting of crevasse geothermal resources in Hainan Island. It is suggested that further improvement and promotion of the method mentioned above is still needed, though it has already achieved good geological effect.
