Embodiment Construction
[0054] The invention discloses the basic structure of a combined well logging instrument which combines natural gamma energy spectrum logging and uranium fission prompt neutron time spectrum logging in the field of uranium exploration and mining (uranium ore exploration and in-situ leaching uranium mining). And the key logging parameter calibration method for determining the content of natural radioactive elements such as uranium, thorium, radium, potassium, etc. in the rock ore layer by using the combined logging. Including the basic structure of the combination logging tool (the block diagram is as follows figure 1 shown), the natural gamma energy spectrum logging data obtained from the scale model well of the measured saturated ore seam (the example results of the natural gamma energy spectrum curve at the center point of the saturated ore seam are shown in Fig. 2(b) to Fig. 3(b), Figure 4 ~ Figure 5 , Figure 6(b) ~ Figure 7(b), Figure 8 , shown in Figure 9(b)), uranium ...
