FIELD: gas and oil production.
SUBSTANCE: calibrating installation consists of set of casings with cement ring and specified defects of structure. Further, the calibrating installation contains a unit reproducing properties of rock and located on a horizontal base. Also, a through channel is made along vertical axis of the unit. The unit reproducing properties of rock is made of two equal movable parts equipped with mechanisms for reciprocal transfer of parts one relative to another along the horizontal base. Vertical plane of their division passes along diametre of the channel. Internal diametre of the channel is equal to external diametre of the cement ring on casings. Also, each casing consists of three successively interconnected sections. The cement ring is located along the central section and is surrounded with a pressure tight case.
EFFECT: raised accuracy of measurements.
