Сальник устьевой относится к нефтяной промышленности и предназначен для герметизации устья нефтяной скважины. Цель изобретения - повышение герметичности сальника устьевого. Для этого сальник устьевой имеет верхнее, среднее и нижнее уплотнения, выполненные в форме полого усеченного конуса. Верхнее и среднее уплотнения помещены в обойму, выполненную в виде полого цилиндра, внутренняя поверхность которого имеет коническое сужение к центру цилиндра, обеспечивающее плотное прилегание уплотнений к внутренней поверхности обоймы. Полость между уплотнениями заполнена маслом для смазки сальникового штока.Wellhead seal refers to the oil industry and is designed to seal the wellhead of an oil well. The purpose of the invention is to improve the tightness of the gland mouth. For this, the wellhead seal has upper, middle and lower seals, made in the form of a hollow truncated cone. The upper and middle seals are placed in a holder made in the form of a hollow cylinder, the inner surface of which has a conical taper to the center of the cylinder, ensuring a tight fit of the seals to the inner surface of the holder.
