Abstract

Настоящее изобретение относится к нефтяными и/или газовым скважинам, в частности к способу и устройству, специально предназначенным для использования на мелководье, где внешние условия создают опасность разрушения находящегося на морском дне скважинного оборудования дрейфующим льдом. Согласно изобретению скважины расположены в полой конструкции (1), которая погружена в морское дно таким образом, чтобы скважины находились на некотором расстоянии ниже морского дна. Полая конструкция (1) содержит фундамент для обеспечения возможности установки опорной плиты (5) для бурения множества скважин. Фундамент выполнен в виде плиты (4) основания, на которой устанавливается опорная плита.Международная заявка была опубликована вместе с отчетом о международном поиске.The present invention relates to oil and / or gas wells, in particular to a method and device specifically designed for use in shallow water, where external conditions create the risk of destruction of downhole equipment on the seabed with drifting ice. According to the invention, the wells are located in a hollow structure (1), which is submerged in the seabed so that the wells are located some distance below the seabed. The hollow structure (1) contains a foundation for allowing the installation of a base plate (5) for drilling a plurality of wells. The foundation is made in the form of a slab (4) of the base on which the base plate is installed. The international application was published along with an international search report.
