Perforating Natural Gamma Ray Tool

Brief Introduction:

AGRT is mainly used to detect the natural gamma rays from formation radiation, and can also be used to determine casing collar position.It applies to logging depth comparison, correction and tracking of cable transmission perforation operation.

The shock-resistant GR logging tool can be directly connected to a perforating gun to achieve depth comparison, correction and perforation in perforation operation within one round trip without need to repeatedly lift or lower the tool. This can greatly improve perforation operation quality, reduce the occurrence probability of accidents such as mistaking perforation etc. as well as labor intensity, and enhance work efficiency.  

The depth correction mode dominated by GR followed by casing collar locator can completely avoid the disadvantages of the traditional casing collar locator and cable perforation mode while retaining its advantages.

 DC power supply is used and two transmission modes are optional (single-pin or 7-pin cable);  

The reliable shock absorption design is such that the tool can resist possible high-intensity impact and vibration during perforation operations;  

The product has higher safety and has passed third-party certifications (ILAC-MRA, CNAS, and CMA).
