Abstract

The invention discloses an azimuth gamma test platform, and belongs to the field of drilling engineering in petroleum, coal mine and geological prospecting. The azimuth gamma test platform comprises astratigraphic modeling part, a connecting rod part and a transmission system, wherein a drill hole is formed in the middle part of the stratigraphic modeling part, the diameter of the connecting rodpart is smaller than the inner diameter of the drill hole, the middle part of the connecting rod part is used for installing azimuth gamma, the transmission system is arranged between the stratigraphic modeling part and the connecting rod part, and the connecting rod part is driven by the transmission system to enable the connecting rod part to rotate relatively in the drill hole of the stratigraphic modeling part and move relatively in the axial direction of a through hole. According to the azimuth gamma test platform, the mutual movement between the stratigraphic modeling part and the connecting rod part provided with the azimuth gamma is controlled, so that the relative movement between the stratigraphic modeling part and the connecting rod part is controlled, the drilling process is simulated, the azimuth gamma is further simulated, tested and calibrated through the simulated real drilling process, the calibration process of the azimuth gamma is close to the real environment, and the test and calibration result is more real.

Description
