The erosion-resistant layer 52 can improve the thermal stability, erosion resistance and impact resistance of the support sleeve 34 and the conversion sleeve 33, and prolong the service life.

[0062] Example Eight: As an optimization of the above examples, as shown in the accompanying drawings Figure 1 As shown, the non-magnetic drill collar 35 is provided with a first connecting hole 43, a second connecting hole 44, a third connecting hole 45, a fourth connecting hole 46 and a fifth connecting hole 47, which are sequentially connected from top to bottom and gradually decrease in diameter. The pressure-bearing outer cylinder 32 is coaxially sleeved in the third connecting hole 45. The upper and lower outer sides of the conversion sleeve 33 are provided with at least one first sealing ring 48 at the upper and lower positions of the second test joint 39. The second sealing ring 49 is provided between the outer side of the support sleeve 34 and the inner side of the fourth connecting hole 46.

[0063] During use, the lower end face of the conversion sleeve 33 contacts the stepped surfaces at the second connecting hole 44 and the third connecting hole 45, and the lower end face of the support sleeve 34 contacts the transition stepped surfaces formed by the fourth connecting hole 46 and the fifth connecting hole 47, which can play a supporting and limiting role. The second slip ring 30 can not only solve the problem of cable connection difficulty when the non-magnetic drill collar 35 and the upper mandrel 9 are docked, but also transmit electrical energy and carrier signals. It can transmit electrical energy to the natural gamma measurement module and the trajectory measurement module. At the same time, the measurement parameters of the natural gamma measurement module and the trajectory measurement module are transmitted to the downhole information interaction module 2, which is convenient for transmission to the surface. By setting the first sealing ring 48 and the second sealing ring 49, it can play a role in isolating mud. After the non-magnetic drill collar 35 comes out of the well, it is easy to disassemble it from the pressure-bearing outer cylinder 32. By setting the second test connector 39, the module can be debugged, tested, and data read, erased and written. As required, the second slip ring 30 is a known through-hole slip ring. The back of the second slip ring 30 is connected to the high-voltage single-core pin, which plays a role in high-voltage isolation, so that the sealing of the non-magnetic drill collar 35 can be controlled independently, avoiding the impact on the operation of other systems after failure.
