三角洲平原

The distribution of the sedimentary microfacies of each sublayer of Chang 6 reservoir is studied, It is concluded that the hydrocarbon accumulation is controlled by sedimentary microfacies. The subaqueous distributary channel of delta front and distributary channel of delta plain are the most favorable facies belts for reservoir distribution and development.

同时对长6油层组各小层沉积微相的时空展布特征进行了分析，认为油气聚集受沉积微相的控制，三角洲前缘亚相的水下分流河道微相和三角洲平原亚相的分流河道微相是砂岩储层分布和发育的最有利相带，也是今后勘探开发的方向。

Lithic associations composed chiefly of quartzose sandstones were developed in delta plains and delta distributary channels with good physical properties to provide available reservoir space.

以石英砂岩为主的岩性组合主要形成于三角洲平原及三角洲前缘分流河道，物性好，提供了良好的储集空间。

It is found that the plain, the front slope and the prodelta of the fan delta have different sedimentary mechanisms, leading to different surface gradients and grain size distributions.

结果表明，扇三角洲平原、前缘斜坡和前扇三角洲3个亚相沉积动力机制不同，导致各相带的扇面坡度和粒度分布特徵明显不同。

认为山西组是在三角洲环境下形成的，主要可采煤层二1煤是三角洲平原上的沼泽沉积。

The sand bodies are made of lithical sandstone with different size. Delta place subfacies and delta front subfacies has been distinguish in the range of oil fields, they were sub...

在大宛齐油区识别出了三角洲平原和三角洲前缘两个亚相并从中进一步划分出了8种微相，查明了康村组岩性由不同粒级的岩屑砂岩的组成，分流河道砂体、水下分流河道砂体和河口砂坝砂体是油气的主要储集层，储层在纵向上多期叠置、在横向上频繁迁移、尖灭和连续性较差。

It is proved that the fan-delta front subfacies including submerged dis

确定出工区在青山口时期主要处于扇三角洲前缘亚相，发育水下分流河道、河口坝、远砂坝和席状砂微相；而在姚家时期主要处于扇三角洲平原亚相，发育河道和河道间微相。

On the plane, the above subfacies can be divided into distributary channel, inter-channel depressions, subaqueous distributary channel and inter-channel bays.

研究区长3期主要发育曲流河三角洲沉积体系，可划分为三角洲平原亚相和前缘亚相，在平面上可划分为分流河道微相、分流间洼地微相及水下分流河道微相及分流间湾微相四种微相类型。

The lithofacies and paleogeography mapping based on high resolution sequence analysis show the sandbody distribution clearly. The paleoshoreline in this area is defined by paleosalinity recovery. Deltaic front subfacies mainly developed in the study area, with small-scale of deltaic plain in northeast.

基于高分辨率层序地层学分析的岩相古地理编图结果非常清晰地显示了研究区长6段砂体展布特征，同时通过古盐度恢复，首次确定了该区湖岸线的位置，从而确定研究区主要发育三角洲前缘亚相，三角洲平原只在东北一隅有小范围分布。

The first sequence in the lower part is one subaqueous-fan~fan-delta depositional system which was caused by alluvial fan intruding lake basin; the lake transgressive system tract and high-stand system tract each contain one coal-seam group; and thick coal seams develop at the edge of subaqueous fan retrograded by lake transgressive system tract and in the region appropriately covered with water in the fan delta of high-stand system tract.

八道壕组可分为三个三级层序，下部第1层序( Sq1)为冲积扇注入湖盆形成的水下扇-扇三角洲沉积体系，湖侵域和高位域各含一个煤组，湖侵域退积的水下扇边缘和高位域扇三角洲平原都有厚煤层发育。

In the fan delta plain, the sediments, with relatively large grain sizes, jump forward with the thrust of water flow, while, in the front slope, the sediments have relatively small grain sizes, weltering and depositing a-long the slope under the force of gravity, forming typical normal grain size gradation.

扇三角洲平原以水流推力作用为主，沉积物以滚动、跳跃方式搬运，粒度最粗；前缘斜坡以重力作用为主，沉积物顺坡向下滚动、沉积，粒度略细，且具有明显的正粒序特徵；前扇三角洲以浮力作用为主，沉积物为悬移质沉降，粒度最细。
