摘要
黄骅坳陷东营组储集性能好,是研究区内的重要油气勘探层段。其砂岩的时空展布与物源有密切的成生联系,物源体系分析是油气勘探工作的重点任务之一。因此,采用统计学中Q型聚类方法对研究区内重矿物的含量变化进行分析,进而划分出不同的矿物组合分区,结合ZTR指数分析和古地貌分析确定对黄骅坳陷东营组沉积起控制作用的物源区有燕山褶皱带、沧县隆起、埕宁隆起和沈青庄地区,这4个物源区分别对黄骅坳陷不同区域的沉积产生重要影响和控制作用。
In Huanghua Depression Dongying Formation, with fine accumulation properties, is the important exploration intervals in the research area. There is intimate relationship between the time and space distribution and material resources for the dispersed system of sand. Material resource system analysis is one key work for hydrocarbon exploration. So, Q-mode clustering procedure used in statistics is applied to the analysis of the change of heavy minerals content in the research area, and then division is made based on different mineral assemblage. With the combination of ZTR index analysis and palaeogeomorphology analysis, it is determined that there are 4 material areas controlling the deposition in Dongying Formation of Huanghua Depression, namely, Yanshan Mountain fold belt, Cangxian Uplift, Chengning Uplift and Shenqingzhuang area. These 4 material areas influence and control the deposition in different regions in Huanghua Depression, respectively.
