水下管汇模块化设计方法及应用

Modular design method and application of subsea manifold

水下管汇是海洋油气生产的重要设备,通常其设计要经历确定参数、画二维图、建立三维模型、调整参数、重绘二维图、重建三维模型等复杂的迭代设计步骤。本次研究引入水下管汇模块化设计的理念,根据中国陵水、流花气田水下管汇的实际设计情况,建立管汇各部件相应的模型库、数据库及模块布置和安装原则,提出了管汇质量计算的理论方法,实现了利用各部件三维模型快速搭建水下管汇、估算水下管汇质量的目标。本文研究成果为水下管汇的前期设计提供了新思路。

Subsea manifold is an important equipment in offshore oil and gas production, and its design usually undergoes complex iterative design steps such as parameter determination, 2 D drawing, 3 D model establishment, parameter adjustment, 2 D drawing redrawing and 3 D model reconstruction. This study introduces the concept of modular design of subsea manifold. According to the design practices of subsea manifold in domestic Lingshui and Liuhua gas fields, the corresponding model library, database and module arrangement and installation principles of each component of the manifold are established, and the theoretical method of manifold mass calculation is proposed. The 3 D model of each component is used to fabricate the subsea manifold quickly and estimate the mass of the subsea manifold. This paper provides a new idea for the early-stage design of subsea manifold.
