摘　　要：对准噶尔盆地莫北油田流体性质及成因研究表明 ,原油分为两类 :第一类原油来源于盆 1井西凹陷二叠系风城组和乌尔禾组烃源岩混源 ,且以后者为主 ;第二类原油主要来源于二叠系风城组烃源岩。天然气为成熟 -高成熟的混合型气。地层水有两种水型 :即 ,NaHCO3型和CaCl2 型 ,但以前者为主。流体在平面分布上受断裂影响较大 ,在纵向分布上存在一定的规律性。The study of fluid property and genesis for Mobei oil field in Zhunge'er basin shows there are 2 types of crude oil in the field. One comes from the mixture of Fengcheng group and Wuerhe group source rocks that appear in Permian of the west sag of Pen Well 1, and the latter governs. The other one comes mainly from Fengcheng group source rocks of Permian. The natural gas belongs to the mixture of mature and high mature gas. The formation water contains 2 types, i.e. NaHCO 3 water and CaCl 2 water, but the former governs. The areal distribution of the fluid is greatly influenced by fractures, and its longitudinal distribution appears some regularity.
