Description

Шарнирное выполнение соединени  заглушек с сердечником исключает вли ние последнего ка жесткость испытуемой трубы; что повышает точность испытаний,The articulated connection of the plugs to the core eliminates the influence of the latter on the rigidity of the test pipe; which increases the accuracy of the test,

Изобретение позвол ет совершенствовать методику расчета обсадных колонн, спускаемых в искривленные скважины в сложных геологических услови х, дающую возможность не только избегать аварий с трубами, но и снизить расход на крепление скважин.The invention makes it possible to improve the method for calculating casing strings being lowered into crooked wells under difficult geological conditions, making it possible not only to avoid accidents with pipes, but also to reduce the costs of well casing.
