Изобретение относитс к сооружени скважин большого диаметра и предназначено дл креплени их.The invention relates to the construction of wells of large diameter and is intended to secure them.
Известен способ креплени скважин большого диаметра двойными колоннами труб с заполнением между ними твердеющей массой, придающей сдвоенным колоннам высокие прочностные свойства против внешних нагрузок Крепление скважин по данному способу выполн ют посредством установки двух труб коаксиально, заполнени полости между трубами твердеющей смесью, установки труб на плавающее днище и погружени креплени в ствол путем наращивани труб с дальнейшим заполнением полости между трубами твердеющим раствором Л .There is a known method of mounting large diameter wells with double columns of pipes with filling between them with a hardening mass, which gives dual columns high strength properties against external loads. The installation of wells with this method is performed by installing two pipes coaxially, filling the cavity between the pipes with a hardening mixture, and installing the pipes on a floating bottom and immersing the mount into the barrel by expanding the tubes with further filling the cavity between the tubes with a hardening solution L.
Недостатком данного способа вл етс длительность технологического процесса из-за бетонировани ,которое занимает много времени на твердение смеси, на укладку бетона и на соединение колец.The disadvantage of this method is the duration of the technological process due to concreting, which takes a lot of time on hardening the mixture, laying concrete and connecting rings.
Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс способ креплени скважин, включающий последовательное введение в скважину внешней и внутренней труб, их совместноеThe closest to the proposed technical essence and the achieved result is a method of mounting wells, including the sequential introduction into the well of the outer and inner pipes, their joint

At the same time, the bolting into the face was carried out after the cement mortar was pumped into the cavity using the 2j method.
Недостаток этого способа состоит в том, что цементирование сдвоенной колонны приводит к увеличению общего The disadvantage of this method is that the cementing of the double column leads to an increase in total
C веса крепи, что может превысить допускаемые нагрузки на вышку. Кроме того, цементирование в таком положении требует, чтобы внутренние трубы были с толщиной стенок, выдерживающих C weight lining that may exceed the permissible load on the tower. In addition, cementing in this position requires that the inner tubes be with wall thicknesses that withstand

Цель предлагаемого изобретени повышение производительности процесса креплени скважин, закачки рас вора и межтрубное и закрепное пр эстран5 ство за один прием.The purpose of the present invention is to increase the productivity of the process of well fixing, pumping the solution, and the annular and fixed pipeline in one step.
Поставленна цель достигаетс: тем, что в способе креплени скважиь,включающем последовательное введение в скважину внешней и внутренней труб, The goal is achieved by the fact that in the method of securing the well, including the sequential introduction into the well of the outer and inner pipes,
