Abstract

Скважинный инструмент (10) выполнен с возможностью приведения в надлежащее состояние ствола (В) скважины и подачи затвердевающего материала, такого как цементный раствор, в кольцевое пространство (А) ствола скважины для крепления и опирания обсадной колонны (С) в стволе (В) скважины содержит корпус в виде трубчатого кожуха (12), вал (14), установленный свободно вращающимся в кожухе (12), головную часть (22) и приводное устройство (20). В случае применения может осуществляться очистка и цементирование ствола скважины посредством направления рабочей текучей среды, такой как буровой раствор, через приводное устройство (20) для приведения во вращение головной части (22) очистки или приведения в надлежащее состояние ствола (b) скважины. Цементный раствор или т.п., может затем направляться через обсадную колонну (С) или через колонну (S) цементирования в вал (14) и через приводное устройство (20), текучая среда затем выпускается из головной части (22).The downhole tool (10) is adapted to bring the wellbore (B) into a proper state and to supply a hardening material, such as cement mortar, into the annular space (A) of the wellbore for fastening and supporting the casing (C) in the wellbore (B) comprises a housing in the form of a tubular casing (12), a shaft (14) mounted freely rotating in the casing (12), a head portion (22) and a driving device (20). In the case of use, the wellbore can be cleaned and cemented by directing the working fluid, such as drilling mud, through a drive unit (20) to rotate the head part (22) of the well or bring the wellbore (b) into proper condition. Cement mortar or the like can then be directed through the casing (C) or through the cementing column (S) to the shaft (14) and through the drive unit (20), the fluid is then discharged from the head portion (22).
