Method for determination of orientation of well axis includes operations on measuring projections of the vector of force of gravity and projections of the vector of absolute angular velocity of rotation of Earth on orthogonal axles of symmetry of the coordinate system of gyroscopic inclinometer placed in the well. On the surface of well one chooses coordinate system oxyz, where the axis oz in directed in vertical of Earth, and to the plane yoz vector of absolute angular rate of rotation of Earth belongs. One measures projections and of the vector on axles oy and oz respectively, and then determines projections Lx, Ly and Lz to the axles ox, oy and oz for unit vector , directed at axis of the well in the place of gyroscopic inclinometer placement. 30032
