大庆长垣以东裕民地区扶余油层物源分析

物源方向研究对古地貌和古构造恢复、沉积砂体的空间展布和物性分布等具有重要的意义。从重矿物组合特征、ZTR指数、泥岩颜色、砂砾岩厚度、沉积相等方面对物源方向进行判断。研究表明,大庆长垣以东裕民地区扶余油层来源于南部长春怀德沉积体系。古物源方向影响沉积砂体的空间展布,控制了大庆长垣以东裕民地区扶余油层沉积体系分布格局,砂体厚度、砂岩展布方向和物源方向有很好的匹配关系。

Provenance Analasis of Fuyu Oil Layers in Yumin Area in the East of Daqing Placanticline

Provenance analysis has important signification in oil and gas exploration for recovering palaeogeomorphology and paleostructure, Spatial Distribution of Depositional sand, Physical Properties. the provenance w as determined according to heavy mineral association, ZTR index, mudstone color zoning, the thickness distribution of sandy conglomerate and sedimentary facies study. The results show that there is only southern Changchun deposition system. Provenance effects Spatial Distribution of epositional sand, furthermore, determines the depositional system pattern of Fuyu oil horizons in Yumin Area in the East of Daqing lacanticline, Spatial Distribution of Depositional sand and thickness distribution of sandy and provenance have favorable spatial matching.
