The invention relates to the technical field of pore inclined measurement, in particular to a method for pore inclined measurement. The method comprises the following step that 1, a clinometer is connected with a cable and then put into an opening of a pore; 2, the XY axis is arranged according to a required direction; 3, the inclination angle of a first point and the angle of the XY axis are measured; 4, the cable is put into the pore according to a set distance, and the inclination angle of a second point and the angle of the XY axis are measured after the cable is stabilized; 5, the actionsin step 4 are repeated until the cable descends to the bottom of the pore, and the inclination angle of the Nth point and the angle of the XY axis are measured. The inclination angle of the pore is measured by using the clinometer, so that the inclination of the pore is obtained, and inclination conditions of the pore are measured. By using an anti-rotation and anti-shaking positioning device, the clinometer is prevented
