摘要:
为弥补在产平台产能不足，需要在平台上增设生产井平台。增设生产井平台在满足需求的前提下，还需考虑避免增设平台对老平台本身的结构强度及稳定性产生的不利影响，同时也要减少海上投入及施工难度，因此按照规范设计出外挂井槽平台结构。通过结合现场施工环境，设计出起到定位及导向作用的M框架及倒置插尖结构，从设计、建造、安装多方面分析研究，成功完成外挂平台与老平台海上安装对接，水平度及平行度满足规范及施工要求，为平台修井机轨道梁的高精度安装奠定了基础，也为后续外扩平台提供了现场经验。 Abstract:Insufficient capacity to compensate for production platforms, require additional production wells on the platform platform.Platform additional production wells on the premise of meeting the needs, also need to be considered to avoid additional platforms on the old platform itself the adverse effects of structural strength and stability, while also reducing offshore investment and construction difficulties, in accordance with specifications designed to plug well tank platform structure.This project through combines site construction environment, design out up to positioning and the oriented role of m framework and the inverted plug pointed structure, from design, and built, and installation multifaceted analysis research, success completed plug-in platform and old platform sea installation docking, level degrees and the parallel degrees meet specification and the construction requirements, for platform repair wells machine track beam of high precision installation lay has based, also for follow-up outside spread platform provides has site experience.
