| 摘 要： | 通过岩心观察、薄片鉴定、测井曲线等资料,对靖安油田长2油层组岩石类型、沉积构造和沉积相特征及砂体分布规律对圈闭的影响进行详细研究.结果表明,研究区长2油层组主要为三角洲平原沉积体系,发育主河道与分流河道砂体,靖安油田受沉积相带、鼻状隆起等因素控制.经油藏分析,靖安油田有利圈闭主要以构造圈闭为主,高闭合度鼻状隆起对油气藏形成具重要控制作用,分流河道汇合部位厚砂体是油气富集主要场所,大规模溶蚀作用形成局部高孔、高渗带是油气聚集成藏的有利地区. |

| Abstract: | Detailed studies have been made on the rock types,sedimentary structures,sedimentary facies characteristics and the distribution of sand body reflection trap of the Interval 2 of Yanchang Formation of Upper Triassic of Jing'an oil field by an integrated analysis of cores, thin sections, well log and other data. the permeability ratio is large. The results show that the Interval 2 of Yanchang Formation is mainly of deltic sedimentary system,Main stream channal and distributary stream channal sand body occurr... |
