FIELD: oil production industry, particularly to measure temperature, pressure and other parameters in pumper well.
SUBSTANCE: method involves eccentrically locating tubing string in casing pipe, wherein in accordance with directional log direction from center of tubing string suspension to face chuck towards center of instrument lowering face chuck orifice is taken as axis of face chuck symmetry. Standoff retainer is installed on clutch. Bottomhole instrument ends are provided with outer conical parts having cone angles of not more than 12°. Orifices for bottomhole instrument passage made in face cluck and standoff retainer are provided with inner correcting conical parts having cone angles of at least 12°.
EFFECT: increased reliability of formation parameter measurements.
