摘要
渤中坳陷石东构造带东营组二段的物源情况不清楚，影响下一步勘探。在层序划分和对比的基础上，利用已钻井重矿物资料进行了物源分析。不同体系的域重矿物含量Q型聚类分析结果表明，可划分出2个重矿物组合区和2种母岩类型，结合重矿物稳定系数所反映的物源方向，明确了该区沉积物来自西部石臼坨凸起和北部辽西凸起，并在后期的勘探实践中得到证实。
In light of the further exploration affected by the unclear source of Dongying-Formation No. 2 Member of Shidong structural belt, on the basis of the sequence division and correlation, the source analyses are discussed with the help of the data of the heavy minerals from the drilled wells. The analyzed results of the Q-mode cluster analysis of heavy mineral content in different system tracts show that two combined regions of the heavy minerals and two kinds of source rocks can be divided. Combined with the source directions reflected by the stability coefficients of heavy minerals, the sediments in the area are made clear migrating from the uplifts of West Shijiutuo and North Liaoxi and furthermore they are prvoen from the the later explorational practice.
