本标准确定了确定阴极保护（CP）需求的程序，以及实现与油气生产和天然气储存相关的井套管阴极保护的当前要求。它还概述了CP系统的设计和安装以及操作和维护的实践。本标准旨在通过提供与井套管相关的CP的可靠信息，确保更有效地防止井套管腐蚀。

This standard identifies procedures to determine the need for cathodic protection (CP) and the current requirements to achieve CP of well casings associated with oil and gas production and gas storage. It also outlines practices for the design and installation of CP systems and for their operation and maintenance. The purpose of this standard is to ensure more effective prevention of corrosion of well casings by making available reliable information about CP as it relates to well casings.
