摘要
综合测井曲线等资料对泌阳凹陷南部核三段沉积微相进行研究。泌阳凹陷南部核三段的平原亚相主要由泥石流沉积、水上分流河道及漫流沉积构成,其中水上分流河道沉积发育较好。扇三角洲前缘亚相主要由碎屑流沉积、水下分流河道沉积、河口砂坝和水下分流河道间组成。前扇三角泥为深灰色及灰黑色泥岩、砂质泥岩、粉砂岩,见水平层理和植物碎屑。
On the basis of the previous studies on key wells, sedimentary microfacies analysis ofthe third members of Hetaoyuan formation (H3 member formation) in southem Biyang Depression are studied. Its plain facies made from debris flow deposit, upper-water distributary channel and inbank flow deposit, and the upper-river channel deposit is better. Subfacies of frontal fan delta mainly includes debris flow deposit, subwater distributary channel deposit, distributary mouth bar and subwater distributary channel. The mood of frontal fan delta is made of deep gray and black gray mudstone, sandy mudstone, siltstone and so on.
