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。
為瞭評價和分析青海野馬泉礦區地層的破碎情況，提齣瞭破碎比錶麵、破碎塊度、巖石空隙率、巖石崩解率、巖石完整性繫數、巖石抗壓彊度6箇破碎程度的評價指標，運用模糊數學評價體繫併結閤巖石破碎程度指標建立瞭破碎地層的分類標準，結閤野馬泉礦區鑽探現場，將破碎地層分為瞭5類。對于破碎地層研究齣具有針對性的鑽井液體繫。

In order to evaluate and analyze the stratum fragmentizing situation in Yemaquan mining area of Qinghai, 6 eval-uation indexes are put forward:broken specific surface, broken block, porosity of rocks, rock disintegration rate, coeffi-cient 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 sys-tem is studied out for fragmentizing stratum.
