Problems solved by technology
[0006] The fixed guide structure will interfere with other operations under the condition of non-decentralized tree, and occupy the deck space for a long time, which is a great waste of limited space;
[0007] However, a single guiding device cannot effectively play a guiding role in the entire lowering space, and it is difficult to be adopted due to the high cost of equipment

The invention discloses a Christmas tree guiding arm of a Christmas tree lowering guiding tool. The Christmas tree guiding arm comprises a head structural piece and a tail structural piece which are perpendicularly arranged in an integrated mode. The head structural piece of the Christmas tree guiding arm is connected with the Christmas tree in a positioning mode, and the tail structural piece of the Christmas tree guiding arm is connected with a guiding arm sliding pedestal into a whole in the positioning mode through a connecting arm and movably connected with a sliding rail of the Christmas tree lowering guiding tool through the guiding arm sliding pedestal. The whole is formed into an independent functional structural piece capable of accompanying and guiding a Christmas tree to be lowered in the vertical direction of the sliding rail. The Christmas tree guiding arm can clasp the hanging Christmas tree, limits swing of the Christmas tree in the horizontal direction, provides guiding and supporting for Christmas tree stable lowering and ensures operation safety of the Christmas tree and a semi-submersible platform.
Description
technical field [0001] The invention belongs to the technical field of offshore production and operation equipment, and relates to a semi-submersible platform for mining [0002] The guide tooling of the oil tree, especially the Christmas tree guide arm of the lowering guide tool of the oil tree. Background technique [0003] The semi-submersible platform has become one of the most important offshore tooling for exploration, drilling, oil production and other production operations in deep sea and far sea due to its advantages such as wide deck space, stable offshore operation, and large variable load. It is an important wellhead control equipment for testing oil (gas) after completion of oil (gas) wells, or when producing oil from gushing wells. [0004] The christmas tree is lowered to the seabed through the drill pipe. During the process of lowering the christmas tree, the entire platform will be affected by the harsh environment such as wind, waves, and air currents at s...
