请注意。本标准的翻译版本中不得包含任何附录或勘误表。本规范提供了石油和天然气行业抽油杆提升方法中使用的地下有杆泵及其部件的设计要求和指南。本规范涵盖了抽油杆提升法常用孔径的地下有杆泵组件（包括插入件和油管）、部件和配件。提供足够的尺寸和材料要求，以确保所有部件的互换性和标准化。本标准规定了许多部件和配件，因此不需要设计包。 然而，有些组件需要设计包。以下表格列出了这些组件:C.10至C.18、C.22、C.23、C.28、C.30、C.32、C.33、C.37、C.38、C.39、C.40、C.41、C.44、C.49、C.53、C.54、C.55、C.59。本规范不包括特殊地下有杆泵附件或特殊设计部件。此外，这些产品的安装、操作和维护不包括在本规范中，但建议可在API 11AR中找到。API规范和API会标计划的制定和发布无意以任何方式阻止从未获得API会标使用许可的公司购买产品。

Please note. Any addenda or errata may not be included in translated editions of this standard.This specification provides the requirements and guidelines for the design of subsurface sucker rod pumps and their components as defined herein for use in the sucker rod lift method for the petroleum and natural gas industry.The specification covers subsurface sucker rod pump assemblies (including insert and tubing), components and fittings, in commonly used bore sizes for the sucker rod lift method. Sufficient dimensional and material requirements are provided to assure interchangeability and standardization of all component parts.Many components and fittings are prescriptively specified in this standard and thus do not require a design package. However, some components require design packages. These components are listed in the following tables: C.10 through C.18, C.22, C.23, C.28, C.30, C.32, C.33, C.37, C.38, C.39, C.40, C.41, C.44, C.49, C.53, C.54, C.55, C.59.The specification does not cover specialty subsurface sucker rod pump accessories or special design components. Also, installation, operation, and maintenance of these products are not included in this specification, however recommendations can be found in API 11AR.The formulation and publication of API specifications and the API monogram program are not intended in any way to inhibit the purchase of products from companies not licensed to use the API monogram.
