现场测试油基钻井液的推荐实践标准程序第一版

" This recommended practice provides standard procedures for determining the following characteristics of oil-based drilling fluids: a) drilling fluid density (mud weight); b) viscosity and gel strength; c) filtration; d) oil, water, and solids concentrations; e) alkalinity, chloride concentration, and calcium concentration; f) electrical stability; g) lime and calcium concentrations, calcium chloride, and sodium chloride concentrations; h) 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 (Annex A); - oil and water concentrations from cuttings (Annex B); - drilling fluid activity (Annex C); - aniline point (Annex D); - lime, salinity, and solids concentration (Annex E); - sampling, inspection and rejection (Annex F); - rig-site sampling (Annex G); - cuttings activity (Annex H); - active sulfide (Annex I);
