本文件涵盖了用于油气井钻井、完井和修井液的重盐水的物理特性、潜在污染物和测试程序。 本文件是对API RP 13J第五版（2014）的补充，其要求适用于本文件规定的例外情况。 与API RP 13J第5版（2014）提供的方法相比，本文件提供了更合适的方法说明，用于在环境压力下测定甲酸盐盐水pH值、碳酸盐/重碳酸盐浓度和结晶温度。 本文件供重盐水制造商、服务公司和最终用户使用。

This document covers the physical properties, potential contaminants and test procedures for heavy brine fluids manufactured for use in oil and gas well drilling, completion, and workover fluids. This document supplements API RP 13J, 5th edition (2014), the requirements of which are applicable with the exceptions specified in this document. This document provides more suitable method descriptions for determining the formate brines pH, carbonate/bicarbonate concentrations and crystallization temperature at ambient pressure compared to the methods provided by API RP 13J, 5th edition (2014). This document is intended for the use of manufacturers, service companies and end-users of heavy brines.
