柴达木盆地尕斯库勒油田N1-N2^1油藏物源方向分析

Analysis of Material Source of N1-N2^1 Reservoir in the GasHure Oilfield of Qaidam Basin

沉积物来源分析是盆地分析的重要内容之一。物源分析在确定沉积物物源位置和性质及沉积物搬运路径,甚至整个盆地的沉积作用和构造演化等方面意义重大。本文针对研究区特性和测试分析等相关资料,采用重矿物分析法、砂岩百分含量和成分成熟度的方法对研究区物源方向进行分析,认为该区物源主要来自北西-北方向和南部方向。

Analysis of sediment source is one of an important content of basin analysis. Source analysis have an important significance to determine sediment source location.character and path of transportation, even entire basin＇s deposition and structural evolution aspect. The text is aimed at correlate information of region＇s character and test analysis, adopt several means which are heavy minerals analysis, proportion of sandstone and maturity of composition to analyse region＇s source direction. In conclusion, the region＇s sediments are mainly sourced from north west-north direction and the south direction.
