本推荐规程提供了测试深水环境中使用的油井水泥浆和水泥混合物的程序，或在海底温度较低的区域或存在低温的区域钻井的程序。在本文件中，“深水”一词包括海底温度较低的区域，与水深无关。本文件中包含的程序可作为深水油井施工中使用的油井水泥浆的测试指南。此外，本文件中包含的测试方法（尤其是泥线条件下的测试方法）也可用于浅水区海底温度较低的情况。 这些条件在北海、挪威海、巴伦支海、卡拉海、波弗特海、楚科奇海、里海和黑海等地区都存在。本推荐规程中包含的试验方法虽然通常基于API 10B-2，但考虑了深水井或海底温度较低区域的井中发现的特殊试验要求和独特的井筒温度剖面。本文件不涉及缓解深水井浅水流动区的问题，API 65《深水井浅水流动区固井》对此进行了阐述。

This recommended practice provides procedures for testing well cement slurries and cement blends for use in a deepwater environment or wells drilled in areas with a low seafloor temperature or areas where low well temperatures exist. For the purposes of this document the term "deepwater" includes areas where low seafloor temperatures exist, independent of water depth.The procedures contained in this document serve as guidance for the testing of well cement slurries used in deepwater well construction. Additionally, testing methods contained in this document (most notably at mudline conditions) may also be used in those circumstances where low seafloor temperatures are found at shallow water depths. These conditions are found in areas including the North Sea, Norwegian Sea, Barents Sea, Kara Sea, Beaufort Sea, Chukchi Sea, Caspian Sea, and Black Sea.The test methods contained in this recommended practice, though generally based on API 10B-2, take into account the specialized testing requirements and unique wellbore temperature profiles found in deepwater wells or wells in areas with low seafloor temperatures. This document does not address the mitigation of shallow water flow zones in deepwater wells, which is addressed in API 65, Cementing Shallow Water Flow Zones in Deepwater Wells.
