摘　　要：安徽六安晓天—磨子潭火山岩盆地深部及外围金铜矿是近年来“以矿找矿”和深部第二空间找矿的重要工作目标。为了从地球物理场的角度有效探测盲矿体空间位置,本文对ZK02进行井中激发极化测井工作,在钻孔4个方位进行供电,利用地—井方式采集钻孔不同深度的视极化率、视电阻率参数,并通过类比向量运算,推算地下地质体空间参数(延伸方向、大小),可为下一步勘探工作提供重要的物探依据。Xiaotian⁃Mozitan Volcanic rock basin in Liuan,Anhui Province is an important target for recent“prospecting⁃for⁃deposits”and deep second space prospecting for gold and copper ores.In order to effectively detect the spatial location of blind ore bodies from the perspective of the geophysical field,this paper conducted in⁃well excitation polarization logging work in ZK02 drill hole.Power was supplied at four locations of the borehole,and the visual polarization rate and resistivity parameters of the borehole at different depths were collected using a ground⁃hole method.Through analogy vector calculation,the underground geological body space parameters(extension direction,size)were calculated,which provided important geophysical basis for the next exploration work.
