摘　　要：埕北306区块油藏馆陶组主要含油层系为馆下段地层,岩性为细中粒长石砂岩,馆下段储集层属辫状河正韵律沉积砂岩,砂体极其发育,但横向连通情况较复杂,且下部多具底水,因此,该油藏开发的关键是准确描述油层的分布。通过对油层的分类,使用微构造研究及测井约束反演的方法进行油层定量描述,落实了储量。The major oil bearing system in Guantao Formation of Chengbei 306 reservoir is Guanxia member layer,which belongs to braided river positive rhythmic sedimentary sandstone with the lithol- ogy of fine-middle grain-size arkose, the sandbodies are highly developed, whereas, transverse connectivity situation is complicated and there is bottom water in most of the lower part. Thereby, the key in this reservoir exploration work is an exact description of oil layers＇ distribution. Microstructure re- search and logging constrained inversion are adopted for quantitative description through division of the reservoirs, thus the reserves are calculated.
