The invention provides a multi-parameter comprehensive well logging exploring tube. The multi-parameter comprehensive well logging exploring tube comprises an exploring tube body. One end of the exploring tube body is connected with a bridle through a first connector, and the other end of the exploring tube body is connected with a quantitative gamma detector through a second connector. A three-lateral center electrode, a bucking electrode and a lead electrode are arranged in the middle of the exploring tube body at intervals. A first insulating spacer and a second insulating spacer are arranged on the two sides of the three-lateral center electrode. A first insulating rod is arranged between the bucking electrode and the lead electrode. A second insulating rod is sequentially arranged between the lead electrode and the quantitative gamma detector. A hole diameter wall is arranged on the outer wall of the exploring tube body. According to the multi-parameter comprehensive well logging exploring tube, multiple parameters are simultaneously collected through one time of well descending, interference between different methods is overcome, the well logging efficiency is improved in multiples, and the well logging cost is reduced.
