本推荐规程为石油和天然气行业固体可膨胀系统的设计、系统验证和应用指南建立了指南。本文件不得用作采购设备的规范；它旨在供用户考虑用于油井应用和固体可膨胀系统的设计。可扩展系统将包括本文定义的井下使用的钻井衬管、吊架、接头、接收器和发射器。本推荐规程仅涵盖永久安装的设备/部件。 本推荐规程不涉及用于管材膨胀的开槽衬套和工具（例如但不限于实施工具、泵、千斤顶和膨胀工具）。本推荐规程的目标是:1）建立制造商和最终用户可以使用的通用术语和方法，2）教育最终用户和制造商，3）确保用户、供应商和制造商理解并能够识别技术的关键方面，4）加速技术并扩大用户群，5）建立统一的评估流程，6）了解技术的可靠性。 用户应注意，本文件中概述的要求可能适用于个别应用。本文件不禁止供应商/制造商提供或用户/买方接受替代设备或工程解决方案。这可能特别适用于有创新或发展中的技术的情况。

This recommended practice establishes guidance for design, system verification, and application guidelines of solid expandable systems for the oil and gas industries. This document is not to be used as a specification for purchasing equipment; it is intended for consideration by users for well applications and design of solid expandable systems.Expandable systems will include drilling liners, hangers, connections, receivers, and launchers for downhole use as defined herein. Only permanently installed equipment/components are covered by this recommended practice. Slotted liners and tools used for the expansion of the tubular goods (such as, but not limited to, implementation tools, pumps, jacks, and expansion tools) are not addressed by this recommended practice.The goals of this recommended practice are to:1) establish common terms and means that can be used by manufacturers and end users,2) educate end users and manufacturers,3) ensure that users, suppliers, and manufacturers understand and can identify the critical aspects of the technology,4) accelerate the technology and expand the user base,5) institute a uniform evaluation process, and6) understand the reliability of the technology.Users should be aware that requirements outlined in this document may be needed for individual applications. This document is not intended to inhibit a supplier/manufacturer from offering, or the user/purchaser from accepting, alternative equipment or engineering solutions. This may be particularly applicable where there is innovative or developing technology.
