FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil and gas industry and is designed for testing boreholes for pressure. Facility for a crushed plug consists of a pipe, in the section of which, in a designed for the plug chamber, there is assembled the plug. The plug contains several round glass disk elements of specified thickness arranged in layers one above the other. The plug in combination with sealing elements tightly closes the passage through the pipe, when a lower side of the plug is installed in the seat of the chamber. Film or sheet of any other, than glass, material is laid between various layers of the plug. The invention facilitates increasing test pressure and withstanding rapid fluctuations of temperature and load.
EFFECT: increasing test pressure and withstanding rapid fluctuations of temperature and load.
