| 摘 要： | 根据层序地层分析的基本思想,从单井岩芯的成因相解释出发,在渤南洼陷沙二段地层进行详细分层对比的基础上,研究了扇三角洲沉积体系,讨论了主要储集岩特征。研究认为渤南洼陷内部沙二段地层发育较好,边缘受凸起抬升和物源供给缺乏的影响,普遍缺失底部砂层;该区沙二段是在浅水湖泊沉积的背景条件下,以扇三角洲体系为主的沉积组合,在研究区...

| Abstract: | According to the theories of sequence stratigraphy and the genetic facies study of well cores,and through a careful stratigraphic analysis of the second member of the Shahejie Formation,the fan delta depositional system and the main characteristics of reservoir rocks were analyzed and discussed.The study indicates that the stratigraphy at inner Bonan Sag is well developed,while the basal sands were generally absent in the raised edge due to the lack of supply source.The fan delta is the main depositional sy... |
