Using the advantage of the invention is that：
1st, the present invention is using monoblock type encapsulation probe, and existing conventional design is pressure balance chamber, the probe security of monoblock type
Reliability is higher than pressure balance lumen type, and monoblock type encapsulation probe can reduce the overall dimensions of measuring pad, be advantageous to number of logging well
According to collection, be advantageous to safeguard and change.The pressure-resistant and heatproof of monoblock type encapsulation pole plate pressure balance chamber than ever refers to simultaneously
Mark is all improved, and can preferably complete well logging demand.
2nd, the shell body in the present invention uses High Strength Wear-Resistance Material, ensures to be effectively protected monoblock type in well logging
Encapsulation probe, the abrasion of probe is reduced, and then increase the service life of pole plate.
3rd, in the present invention, a pair of pole plate sides, which surround, utilizes the design feature of itself, firmly will be whole by high-strength screw
Drilling tool memory-type imaging measurement pole plate is crossed to be fixed together.
