Wellhead piece installation method
The invention discloses a wellhead piece mounting method. The wellhead piece mounting method comprises the following steps: S1, prefabricating a wellhead piece and a deck piece on land; s2, the upper stand columns penetrate through the deck pieces, and the deck pieces are reinforced through tie bars; s3, sliding shoes are installed in the middle of the bottom face of the bottommost deck piece, wellhead pieces are installed on the two sides of the bottommost deck piece through temporary supporting pipes, and the wellhead pieces are connected with the bottommost deck piece through chain blocks; s4, a supporting pipe is placed on the bottommost deck piece, and the whole assembly is moved to a transport ship through sliding shoes; s5, driving the transport ship to a proper position on the sea, aligning the upper stand column to the lower stand column, and slowly lowering and connecting; s6, the temporary supporting pipe is cut off, the chain block is lowered to a proper position, a supporting pipe is welded to the position of the original temporary supporting pipe, and at the moment, the wellhead piece is located at the proper position of the upper end of the oil guide pipe; and S7, the transport ship leaves, and operation is completed. According to the method, land integrated construction is adopted, wellhead piece prefabrication is completed ashore, and collision with a transport ship and an oil guide pipe during in-place installation is avoided.
本发明公开了一种井口片安装方法，包括以下步骤：S1、在陆地进行井口片和甲板片预制；S2、将上立柱穿过甲板片，并且甲板片之间用拉筋加固；S3、在最底层甲板片底面中部安装滑靴，两侧通过临时支撑管安装井口片，井口片还有倒链与最底层甲板片连接；S4、将支撑管放置在最底层甲板片上，将整个组件通过滑靴移到运输船上；S5、将运输船行驶到海上合适为止，将上立柱对准下立柱并且缓慢下放连接；S6、切断临时支撑管，下放倒链至合适位置，在原临时支撑管的位置焊接支撑管，此时井口片位于导油管上端合适位置；S7、运输船驶离，完成作业。本发明采用陆地一体化施工，在岸上完成井口片预制且避免了安装就位时与运输船和导油管的碰撞。
