Ambient environment analysis method, azimuth gamma probe tube and logging instrument

The invention relates to a surrounding environment analysis method, an azimuth gamma probe tube and a logging instrument. The method comprises the following steps: establishing a first fluctuation curve based on an electric signal on a moving track of the azimuth gamma probe tube; synchronously detecting the thickness of a mud shell on the outer wall of the drill bit in the process of establishing the first fluctuation curve, and correcting the first fluctuation curve by using a mud shell thickness value to obtain a second fluctuation curve; at least one interface is determined according to the curvature change of the second fluctuation curve, a plurality of exploration areas uniformly exist around the movement track of the azimuth gamma probe on the plane perpendicular to the movement track of the azimuth gamma probe, and when the interfaces exist in the exploration areas with the number larger than or equal to the set number, the azimuth gamma probe is located in the exploration areas. And determining that
