Description

Изобретение относитс  к опорам буровой вышки, устанавливаемым на морском дне.The invention relates to derrick supports mounted on the seabed.

Существующие опоры, пригодные дл  закреплени  их на песчаном дне, оказываютс  непригодными дл  закреплени  их на илистом дне с мощным слоем йла, ввиду того, что ил выдавливаетс .Existing supports suitable for fixing them on a sandy bottom are not suitable for fixing them on a silty bottom with a thick layer of mud, because sludge is being squeezed out.

В предлагаемой опоре этот недостаток устранен тем, что опора выполнена в виде служащего анодом цилиндра, а стойка, проход ща  по оси цилиндра, снабжеца в нижней части фильтром дл  прокачки химических реагентов, который служит катодом при электростабилизации грунта.In the proposed support, this disadvantage is eliminated by the fact that the support is made in the form of an anode cylinder, and the stand, which passes along the axis of the cylinder, is supplied at the bottom by a filter for pumping chemical reagents, which serves as a cathode during the electrical stabilization of soil.

Согласно изобретению, цилиндр, служащий анодом, имеет диаметр до 1,5 м, высота его 0,7 м, причем верхн   часть жестко соединена со стойкой. Этот цилиндр врезаетс  в грунт, что исключает выдавливание грунта из-нод опоры, так как сразу же переносит нагрузку на более глубокие слои.According to the invention, the cylinder that serves as the anode has a diameter of up to 1.5 m, its height is 0.7 m, and the upper part is rigidly connected to the stand. This cylinder cuts into the ground, which eliminates the extrusion of soil from the support nodes, as it immediately transfers the load to the deeper layers.

С целью исключени  выдавливани  грунта через полые трубчатыеIn order to prevent the extrusion of soil through hollow tubular

стойки опоры и увеличени  несущей способности илистого грунта, примен ют посто нный электрический ток дл  обезвоживани  и закренлени  грунта внутри цилиндра.supports and an increase in the carrying capacity of silt soil, use constant electric current to dewater and ground the soil inside the cylinder.

Дл  усилени  сцеплени  буровой трубы с грунтом примен ют электрохимический способ закреплени  грунтов, который позвол ет в несколько раз увеличить несущую способность металлической сваи.To enhance the adhesion of the drill pipe to the ground, an electrochemical method of securing soils is used, which makes it possible to increase the bearing capacity of the metal pile several times.

На фиг. 1 показана конструктивна  схема опоры. Стойка / скреплена косынками 2 с цилиндром 3 и имеет фильтр 4 с пробкой 5.FIG. 1 shows a structural diagram of the support. Rack / fastened with kerchiefs 2 with cylinder 3 and has a filter 4 with a plug 5.

На фиг. 2 показана схема установки основани  под вышку на илистом морском дне. Опоры 6 врезаютс  в грунт, заанкериваютс  сначала временными гарпунными анкерами 7, а затем посто нными анкерами 8.FIG. 2 shows the installation of the base under the tower on a silty seabed. The supports 6 cut into the ground, anchor first with temporary harpoon anchors 7 and then with permanent anchors 8.

Предлагаема  опора стойки основани  морской буровой вышки позвол ет не доводить опору до коренных пород и увеличить несущую способность илистого грунта путем применени  способа электрохимического креплени  грунта.The proposed support of the stand of the base of the offshore oil rig makes it possible not to bring the support to the bedrock and to increase the bearing capacity of the silt soil by applying the method of electrochemical fastening of the soil.

Предмет изобретени Subject invention

Опора стойки основани  морской буровой вышки, установленна  на илистом грунте, уплотненном электрохимически стабилизированным посто нным током, отличающа с   тем что дл  осуществлени The support stand of the base of the offshore oil rig, installed on silty soil compacted with electrochemically stabilized direct current, is characterized in that

электростабилизации грунта в нроцессе установки вышки опора выполнена в виде служашего анодом цилиндра, ее стойка снабжена в нижней части фильтром дл  прокачки химических реагентов, который служит катодом при электростабилизации илистого грунта.electrostabilization of soil in the process of installation of the tower, the support is made in the form of an anode cylinder that serves as an anode; its stand is provided in the lower part with a filter for pumping chemical reagents, which serves as a cathode in electrostimization of silt soil.
