FIELD: oil and gas industry.
SUBSTANCE: in particular, there is an orientation indication device provided, which includes a body forming the first flow channel and mounted inside a well pipe; an orientation device movably mounted inside the body and forming the second flow channel in fluid communication with the first flow channel; and an eccentric weight mounted inside the orientation device and having a center of mass radially displaced from the rotation axis of the orientation device. At that the eccentric weight is made with the possibility of holding the orientation device pointing one direction at the rotation of the body and the well pipe, at that during the rotation of the body, the first and the second flow channels are gradually aligned or lose alignment.
EFFECT: convenient and accurate realization of azimuth orientation.
