用以研究地层,可深透干旱地层。在电极相距几千米时测量精度可达±1微伏。仪器由测量部分GGA30M和电源部分GGA30组成。用新的求值方法采用低的电极电压也可进行准确测量。有效地抑制干扰电压,提高了灵敏度。有电势差的电极电路中,若灵敏度增加10倍与电极电能增加100倍等效。本仪器在减轻重量、增加穿透深度以及节省电极功率方面都有所改进。由于可降低电极电压用较小电极功率测量,安全程度加强。
Used to study the formation, can penetrate the arid formation. Measurement accuracy can be ± 1 microvolt when electrodes are several kilometers apart. The instrument consists of a measuring section GGA30M and a power section GGA30. The new method of evaluation using low electrode voltage can also be accurately measured. Effectively suppress the interference voltage, improve the sensitivity. In the electrode circuit with potential difference, if the sensitivity is increased by 10 times and the electrode power is increased by 100 times, it is equivalent. The instrument improves weight, increases penetration depth, and conserves electrode power. Increased safety due to lower electrode power measurements that reduce electrode voltage.
