偶极-偶极测量装置是电法测量中最常见的方法.在本文所提及的斑岩铜矿的勘探项目中,偶极-偶极激电测量作为主要的地球物理勘查方法被广泛使用.但是由于研究区某些区域十分崎岖的地形和很差的进入条件,我们对偶极-偶极装置进行了一定的改进以适应环境的需要.改进后的方法称之为“双极-偶极”.为了研究“双极-偶极”的有效性及其与偶极-偶极之间的差异,在同一测线,相同点位上,利用相同的设备,以相同的点距和仪器参数对两种方法进行了对比实验测量.并且简便起见,采用了与偶极-偶极相同的成图方法.随后,对测量数据和拟断面进行了详细的数据分析,最后对两种数据进行了二维反演.分析结果表明:(1)双极-偶极和偶极-偶极方法同样有效(2)双极-偶极和偶极-偶极在充电率结果上有一定差异,但差异很小(3)双极-偶极和偶极-偶极所测得的电阻率有较明显差异,但依然显示出总体的一致性.总而言之,对比试验证明,双极-偶极是非常有效的测量方法.在偶极-偶极难以实施的地方,可以作为偶极-偶极装置的有效补充和替代方法.
Dipole-dipole measurement devices are the most common methods used in electrical method measurements. Among the porphyry copper exploration projects mentioned here, dipole-dipole-dipole measurements are widely used as a major geophysical prospecting method However, due to the rugged terrain and poor access conditions in some areas of the study area, we have made some improvements to the dipole-dipole device to meet the needs of the environment.The improved method is called “bipolar-even In order to study the validity of ”bipolar-dipole" and its difference from dipole-dipole, at the same line, at the same point, using the same device, with the same point Distance and instrument parameters of the two methods of comparative experimental measurements.And for the sake of convenience, with dipole - dipole the same mapping method.Secondly, the measured data and the quasi-section of the detailed data analysis, the last two The results show that: (1) bipolar - dipole and dipole - dipole methods are equally effective (2) bipolar - dipole and dipole - dipole charge rate results Some differences, but little difference (3) Bipolar - dipole and dipole - dipole measured resistivity more obvious difference , But still show overall consistency.In summary, comparative experiments prove that bipolar-dipole is a very effective measurement method.It can be used as an effective complement to dipole-dipole where dipole-dipole is difficult to implement And alternative methods.
