摘要
东营组是黄骅坳陷的重要的油气勘探层段之一。从ZTR指数、矿物的成分成熟度指数、岩屑组成以及砂体展布特征等方面对东营组的物源方向进行分析,明确了该区东营组存在4大物源区,即燕山褶皱带、沧县隆起、沙垒田凸起和埕宁隆起,这4个物源控制着当时沉积体系的时空展布样式。
Dongying Formation is one of the important oil and gas exploration zones in Huanghua Depression, the source direction of Dongying Formation is analyzed according to the characteristics of ZTR coefficient, maturity index of mineral composition, debris composition and sandbody distribution characters, 4 source regions, such as Yanshan fold belt, Cangxian uplift, Shaleitian swell and Changling uplift are clarified in the formation, by which space distribution mode of deposit were controlled at that time.
