石油和天然气工业.钻井和生产设备.海上导体设计、设置深度和安装

[中文适用范围]： 本文件规定了海上石油和天然气工业导体的设计、埋设深度和安装的要求和建议。 本文件具体涉及： ——导体的设计，即直径、壁厚和钢种的确定； ——掘进、钻固、喷射三种安装方式的设定深度的确定； ——三种安装方法的要求，包括适用性、程序、文件和质量控制。 本文件适用于： ——平台导线：通过平台钻台上的导向孔安装，然后通过水柱间隔地附在导管架上的导向装置来支撑导线，承受作用，并防止过度位移； ——自升式支撑导线：仅在钻井作业期间使用的临时导线，由自升式钻井平台安装。 在某些情况下，导体通过连接到钻机的张紧器张紧； ——自立式导体：安装在浅水中的悬臂式自支撑导体，通常水深约为 10 m 至 20 m。 它为井提供唯一的支撑，有时支撑小型通道甲板和船只着陆； ——海底井口导线：完全浸没的导线，仅延伸到距海底几米的地方，防喷器和钻井立管连接在其上。 钻井隔水管连接到浮动钻机。 防喷器、立管和钻机会受到波浪和水流的作用，而立管也会受到 VIV 的影响。 本文件不适用于钻井隔水管的设计。 [外文原描述]： This document specifies the requirements and recommendations for the design, setting depth and installation of conductors for the offshore petroleum and natural gas industries. This document specifically addresses: — design of the conductor, i.e. determination of the diameter, wall thickness, and steel grade; — determination of the setting depth for three installation methods, namely, driving, drilling and cementing, and jetting; — requirements for the three installation methods, including applicability, procedures, and documentation and quality control. This document is applicable to: — platform conductors: installed through a guide hole in the platform drill floor and then through guides attached to the jacket at intervals through the water column to support the conductor, withstand actions, and prevent excessive displacements; — jack-up supported conductors: a temporary conductor used only during drilling operations, which is installed by a jack-up drilling rig. In some cases, the conductor is tensioned by tensioners attached to the drilling rig; — free-standing conductors: a self-supporting conductor in cantilever mode installed in shallow water, typically water depths of about 10 m to 20 m. It provides sole support for the well and sometimes supports a small access deck and boat landing; — subsea wellhead conductors: a fully submerged conductor extending only a few metres above the sea floor to which a BOP and drilling riser are attached. The drilling riser is connected to a floating drilling rig. The BOP, riser and rig are subject to wave and current actions while the riser can also be subject to VIV. This document is not applicable to the design of drilling risers.
