Suction pile type multi-wellhead base plate suitable for deepwater shallow soft stratum
The invention discloses a suction pile type multi-wellhead base plate suitable for a deep water shallow soft stratum. The suction pile type multi-wellhead base plate comprises a truss structure, at least two suction piles, at least two center pipes and at least two spraying devices. The truss structure is connected to the tops of the at least two suction piles; the central pipe is inserted into the suction pile and is used for guiding in a guide pipe; the spraying device comprises a water sprayer and a porous water pipe which are connected; the water sprayer is arranged on the side, close to the center of the truss structure, of the top of the suction pile. The porous water pipes are distributed on the outer side walls of the suction piles; according to the suction pile type multi-wellhead base plate, two or two suction piles are combined to serve as the wellhead base plate, so that the bearing capacity of the wellheads is improved, dangers such as sinking of the wellheads are effectively prevented, the space in the suction piles is effectively utilized, the problem that the number of wellhead grooves is limited is solved, the cost of drilling engineering is reduced, and economic benefits are improved; and by arranging the spraying device, soil blockage between two or more suction piles is effectively prevented.
本发明公开了一种适用于深水浅软地层的吸力桩式多井口基盘，包括桁架结构、至少两个吸力桩、至少两根中心管和至少两个喷冲装置；桁架结构连接于至少两个吸力桩的顶部；中心管插设于吸力桩内，用于导入导管；喷冲装置包括连接的喷水器和多孔水管；喷水器设置于吸力桩的顶部靠近桁架结构中心的一侧；多孔水管布设于吸力桩的外侧壁；该吸力桩式多井口基盘将两个或两个吸力桩组合后作为井口基盘，不仅提高了井口承载力，有效防止了井口下沉等危险的发生，还将吸力桩内的空间进行有效利用，解决了井口槽数量有限的问题，降低了钻井工程的成本，提高了经济效益；通过设置喷冲装置，有效防止了两个或两个以上吸力桩之间发生土塞。
