摘要： 以重力流沉积理论为墓拙，在金华地区大安寨段介厉灰宕中划分出领并流和浊流两种不同类型的沉积抽，其沉积模式为重力流湖底扇相;硕料流沉积物的储集性远优于浊流沉积物，该区高产井和不产井的交叉出几原因在于高产升隽于顺抖流发育的网状分流水道之中，而不产并处在浊流为主的受及扇舌形体之上;可根据扇内水道的分布规律，预测有利的含油气区块。

Abstract: Owl the basis of gravity flow theory，two kinds of sediment，grain flow sediment and turbidity current sediment，have been distinquished in the Liptodetrinite limestone of naa"zzhai Member in Jinhua area，Central Sichuan. The sedimentary model is lake-bottom fan of gravity flow. Grain flow sediments. have a much better accumulative property than turbidity current sediments. In this area，the alternative distribution of high and low produc-tivity wells Ties in the fact that high-productivity wells are in netted separate waterways where grain flow sediments are rich while low-productivity wells are on repeated tongues of fan where turbidity current sediments are rich. According to the distribution law of water-ways in fans，favourable regions containing oil and gas can be predicted.
Key words: Sedimentary microphase, Reservoir model, Turhidity current, Lake-bott-tom fan, Characteristics containing oil and gas, Daanzhai member, Jin Hua area.
