| 中文摘要:为了评价和分析青海野马泉矿区地层的破碎情况，提出了破碎比表面、破碎块度、岩石空隙率、岩石崩解率、岩石完整性系数、岩石抗压强度6个破碎程度的评价指标，运用模糊数学评价体系并结合岩石破碎程度指标建立了破碎地层的分类标准，结合野马泉矿区钻探现场，将破碎地层分为了5类。对于破碎地层研究出具有针对性的钻井液体系。 |

| Abstract:In order to evaluate and analyze the stratum fragmentizing situation in Yemaquan mining area of Qinghai, 6 evaluation indexes are put forward: broken specific surface, broken block, porosity of rocks, rock disintegration rate, coefficient of rock integrity, compressive strength of rock. The fragmentized stratum classification standard is established by using fuzzy mathematical evaluation system and combining with rock fragmentized degree index; and combined with the drilling site situation of Yemaquan mining area, the fragmentized stratum is divided into 5 categories. A targeted drilling fluid system is studied out for fragmentizing stratum. |
