| 摘 要： | 通过对研究区内12口钻井岩芯的岩石学特征、沉积构造等特征的综合认识,结合沉积微相平面展布及连井地层对比,对麻黄山西区块三叠系延长组长61油层组进行了沉积环境分析,识别出6种沉积构造,5种沉积微相,总结出6种微相接触样式.研究结果表明,延长组长61油层组为三角洲前缘沉积,垂向上表现为以反韵律为主伴有短期正韵律的沉积特征,...

| Abstract: | By comprehensive understanding of more than 12 wells in rock core characteristics and sedimentary structures characteristic in study area,combining logging data,distribution and fine comparison,the sedimentary environment of the study area are analyzed,and 6 kinds of sendimenty structures,5 kinds of the main sedimentary microfacies and 6 kinds of micro-contact styles are identified.The results show that Chang 61 formation is front of delta.Anti-rhythm is mainly in vertical and positive rhythm in short period.It reflects the process of constant progradation. |
