| 摘 要： | 松辽盆地南部伏龙泉气田下白垩统泉头组一段为主力产气层段，但从未进行过系统的沉积微相研究。从岩芯分析入手，结合区域地质资料、测录井资料，利用岩石相与测并相转换技术对工区内泉一段的沉积微相进行了刻画，提出伏龙泉气田下白垩统泉头组一段属于辫状河沉积体系，共识别出心滩、河道滞留、泛滥平原和决口扇四种沉积微相，建立了辫状河垂向沉积层序，并对其沉积微相平面展布特征进行了研究。泉一段为辫状河沉积，心滩发育，河道边部发育大面积的泛滥平原，心滩砂体呈透镜状，平行于水流方向在河道内分布，垂向上交错叠置，横向上大规模连片，分布稳定并具有较好连通性。

| Abstract: | Systematic sedimentary mircofacies research has never been done in Quan 1 section that is the principal sec- tion of Fulongquan gas field located in the south Songliao basin. The authors start with core analysis and regional geological data, logging data, using petrologic phase and electrofacies switching technology to divide and compare the sedimentary mir- coracles of the Quan 1 section in the area, first put forward braided river deposition system. And therefore to further recog- nize sedimentary mircofacies such as channel lag, mid-channel bar crevasse splay, flood plain, establish vertical sedimentary sequencesthe of braided river, study on the planar distribution characteristics, provide an important basis for prediction of sand body distribution and reservoir 3-d attribute modeling, provide necessary warrant for high effective development of Fu- longquan gas field. |
