标准摘要
[中文适用范围]: 重晶石用于增加油井钻井液的密度。它是一种开采产品,除其主要成分硫酸钡外,还含有大量矿物质。表 1 列出了一些通常与重晶石矿石伴生的矿物,其中包括化学式、矿物学名称和矿物颗粒的密度。重晶石在钻井液中的性能部分与重晶石矿石中分布的非重晶石矿物的百分比和类型有关。其中一些矿物质对钻井液特性影响很小或没有影响,但其他矿物质会降低这些特性,甚至对钻井人员有害。本出版物的目的是提供定量测定重晶石矿物和化学成分的化学分析程序的全面、详细的描述。这些程序非常复杂,通常在设备齐全的实验室中进行 [外文原描述]: Barite is used to increase the density of oil well drilling fluids. It is a mined product that can contain significant quantities of minerals other than barium sulfate, which is its main component. It is the objective of this publication to provide a comprehensive, detailed description of the chemical analytical procedures for quantitatively determining the mineral and chemical constituents of barite. These procedures are quite elaborate and will normally be carried out in a well-equipped laboratory.
