Drilling platform pile shoe structure
The invention discloses a drilling platform pile shoe structure, and relates to the field of offshore oil and gas development, the drilling platform pile shoe structure comprises a pile shoe body connected to the bottom of a pile leg, a plurality of annularly and uniformly distributed puncture holes are formed in the bottom surface of the pile shoe body, the drilling platform pile shoe structure further comprises puncture columns in one-to-one correspondence with the puncture holes, and the puncture columns are locally located in the pile shoe body. The top end of the puncture column is located in the pile leg. And the driving mechanism is used for driving the puncture column to ascend and descend and is located in the pile leg. According to the drilling platform pile shoe structure, the problem that in the prior art, the drilling platform pile shoe structure cannot be suitable for synchronous puncture damage of an egg shell stratum with the surface layer overlying strata being relatively thick is solved, and the purposes of improving the synchronous active puncture capacity in the self-elevating drilling platform pile inserting process and expanding the application range of the synchronous active puncture technology are achieved.
本发明公开了一种钻井平台桩靴结构，涉及海洋油气开发领域，包括连接在桩腿底部的桩靴本体，所述桩靴本体底面开设若干环形均布的穿刺孔，还包括与所述穿刺孔一一对应的穿刺柱，所述穿刺柱局部位于桩靴本体内部，且穿刺柱的顶端位于桩腿内部；还包括用于驱动所述穿刺柱升降的驱动机构，所述驱动机构位于桩腿内部。本发明提供一种钻井平台桩靴结构，以解决现有技术无法适用于表层覆岩相对较厚的“鸡蛋壳地层”的同步穿刺破坏的问题，实现提高自升式钻井平台插桩过程中的同步主动穿刺能力、扩大同步主动穿刺技术适用范围的目的。
