标准摘要
[中文适用范围]： 目前，关于钻井液中重量材料沉降相关流变参数的测量设备或方法尚无公认的行业标准。普遍认为，在低剪切速率（小于1.0 s−1）下的粘度测量以及从振荡测量中得出的各种流变参数对于量化流体实际或潜在的重量材料沉降能力是有用的。本条款适用于现场钻井液和实验室混合的流体。 [外文原描述]： ISO 10414-2:2011 provides standard procedures for determining the following characteristics of oil-based drilling fluids: drilling fluid density (mud weight); viscosity and gel strength; filtration; oil, water and solids concentrations; alkalinity, chloride concentration and calcium concentration; electrical stability; lime and calcium concentrations, calcium chloride and sodium chloride concentrations; low-gravity solids and weighting material concentrations. The annexes provide additional test methods or examples that can optionally be used for the determination of: shear strength oil and water concentrations from cuttings; drilling fluid activity; aniline point; lime, salinity and solids concentration; sampling, inspection and rejection; rig-site sampling; cuttings activity; active sulphides; calibration and verification of glassware, thermometers, viscometers, retort kit cups and drilling fluid balances; permeability plugging apparatus with set-screw secured end cap; permeability plugging apparatus with threaded end cap; elastomer compatibility; sand content of oil-based fluid; identification and monitoring of weight-material sag; oil-based drilling fluid test report form.
