Asluvial structures of fluvial facies are affected by each effect between supplying of taliment and pnducing of accommedately room. The recognition of their Sequence and systern tract is according to situation of piling up of channel sand they and develoPment of palesoil or nuvial type: no recod of sediment in the early LST and braided stream in the later LST, meandeting stream and anastomosing strearn in TST, meandering strearn in HST, braided strearn in the Rar.

河流相的层序地层结构是由沉积物的供给和可容纳空间之间的相互作用决定的,其居序与体系域的识别和划分则是根据河道砂体的叠置方式及相伴生的古土壤的发育情况或河流类型来进行的,低水位早期主为侵蚀下切无沉积记录,低水位晚期主为辩状河;水进时期先为曲流河、后为网状河;高水位时期为曲流河,水退时期主为辩状河。

On comparison of the found oil and gas reserves with the different scale sequence boundaries and reservoirs in system tracks in the Jiyang Depression, it is found that the reserves of oil and gas in glutenite reservoirs of low frequency sequence are real huge, and those in glutenite reservoirs of medium frequency sequence are in the medium, and those in glutenite reservoirs of high frequency sequence are minimum. In transgresssive system tracks, oil and gas reservoirs developed not well, and the oil and gas...

On comparison of the found oil and gas reserves with the different scale sequence boundaries and reservoirs in system tracks in the Jiyang Depression, it is found that the reserves of oil and gas in glutenite reservoirs of low frequency sequence are real huge, and those in glutenite reservoirs of medium frequency sequence are in the medium, and those in glutenite reservoirs of high frequency sequence are minimum. In transgresssive system tracks, oil and gas reservoirs developed not well, and the oil and gas reserves in them are very small. In fluvial highstand system tracks, the shape of the reservoirs is lenticular, with good sealing conditions, so the reserves of oil and gas in this kind of reservoir are great. In lacustrine highstand system tracks, the effects of progradational parasequence sets and para sequence boundaries of delta facies on the trapping of oil and gas depend on subsequent tectonic movements. The subsequent tectonic movements did not influence the oil bearing degree of reservoirs in lowstand tracks, but could strongly increase sealing capability of reservoir in highstand tracks through changing original geometric configuration and trend of sequence strata, and then improved oil bearing degree.

将济阳坳陷不同级别的层序边界及层序内各体系域发育的储集层与油气探明储量的关系进行对比 ,发现处于主要烃源层之上的低频层序的低位体系域中发育的砂砾岩储集层油气储量最多 ,中频层序的低位体系域发育的储集层油气储量中等 ,高频层序的低位体系域中发育的储集层油气储量最少。湖侵体系域中油气储集层相对不发育 ,油气储量较少。河流相层序高位域发育的储集层呈透镜状 ,封闭性好 ,因此含油性好。湖泊相层序高位域的三角洲相进积式准层序组和准层序边界对油气封闭性的影响取决于后期的构造变动 ,后期构造活动不影响低位域储集层的含油气性 ,但通过改造高位域原始层序地层几何形态和倾向 ,可以大大增加高位域储集层的封闭性 ,从而提高其含油气性。图 4表 1参 15

The principles of sedimentology and sequence stratigraphy were used to research the mode of sequence stratum of coastal alluvial environment. An universal mode for sequence stratum of alluvial-fluvial facies was established. The relationship between system tract and sedimentary facices was discussed on the analysis of river types of the Neogene in Jiyang Depression. The results show that there are four types of system tracts in alluvial-fluvial facies including low system tract, extension system tract, high system tract, contracting system tract. According to the sedimentary characteristics of the Neogene in Jiyang Depression, the types of sediment system and facies corresponding to the different system tracts were given. There were alluvial-braided river facies in low system tract. The braided river was transited to meandering river in extension system tract. There was meandering river in the high system tract, and the meandering river was transited to braided river in the contracting system tract.

运用沉积学及层序地层学原理 ,分析了河流类型及其形成发育特征 ,借鉴国内外有关冲积河流环境下的层序地层模式 ,特别是近海冲积环境下层序地层模式 ,并以济阳坳陷新近系为例 ,建立了更具普遍意义的冲积河流相层序地层模式 ,探讨了不同体系域的特征及其与河流类型之间的关系。研究结果表明 ,冲积河流相地层的体系域划分具有 4分性特征 ,即主要发育有低水位体系域、扩张体系域、高水位体系域 ,当基准面缓慢下降时 ,还可发育收缩体系域。根据济阳坳陷新近系沉积特征 ,指出了各体系域对应的沉积体系及相类型。其中 ,低水位体系域时期以侵蚀下切、冲积扇辫状河沉积为主 ;扩张体系域时期是由辫状河向曲流河过渡 ;高水位体系域时期以曲流河为主 ;收缩体系域时期是由曲流河向辫状河过渡。
