The utility model relates to a well logger with double gamma-ray detectors. The well logger with double gamma-ray detectors comprises a 1553 coding/decoding device, a control switch, a high voltage power supply module, a double gamma-ray detector composed of Geiger-Muller tubes, a signal shaping circuit, a double gamma-ray counter, a multiplexer and a corresponding mechanical structure. The gamma detector module of the well logger with double gamma-ray detectors is composed of two opposite Geiger-Muller tube detection units having two independent detection circuits so that two independent natural gamma ray detection operations can be carried out. The well logger with double gamma-ray detectors of the utility model can provide a gamma counting value with high precision and can continuously and stably work under a high temperature environment of 150 DEG C.
