摘要 |
FIELD: physics. ^ SUBSTANCE: in the body of the monolithic block of a device for calibrating downhole equipment, there are through channels which lie parallel and concentric to the vertical axis of the device. All or some of said channels are filled with hydrogen-containing material in form of caprolon rods of the same or different cross-section. At the bottom, the channels may be fitted with valves and all or some are filled with water. ^ EFFECT: high accuracy of calibrating equipment used on gas fields and underground gas storages. ^ 3 cl, 1 dwg |
