三角洲平原

Normally, the reservoirs in the delta front have weaker sensitivity to fluid than the reservoirs in delta plain.

在临南油田，三角洲前缘亚相的储层敏感性弱，三角洲平原亚相的储层敏感性较强。

Delta plain divided distributary river course and between river courses.

三角洲相区分为三角洲平原、三角洲前缘和前三角洲三个亚相。

The deposital system was composed of three whole deposital association including delta plain, the front of delta and frontal delta.

其中该三角洲体系由三角洲平原、三角洲前缘和前三角洲三个完整的沉积组合构成。

Research results show that the warden 4 + 5 to 6, meandering river delta depositional belongs to the reservoirs mainly development phase, the delta plain and sedimentary microfacies in distributary channel, and channel between.

研究结果表明该区长4+5为曲流河沉积，长6油层组沉积属于三角洲相，主要发育三角洲平原亚相，沉积微相以分流河道和河道间为主。

The technique of stratal slices can reveal the isochronism of sediment disperal patterns with high-resolution. And the sedimentary systems can be analyzed with lithologic log data. A shelf-edge deltaic system including fluvial plain, deltaic plain, deltaic-front, prodelta, and incised valleys was identified in Olmos formation of Gold River North Oilfield.

相位转换后可以通过地震振幅分析岩相；地层切片技术能更精确地反映研究区等时的沉积分布特征，结合岩性测井资料可以较准确地分析沉积体系；Olmos组可以识别出一套河流－三角洲沉积体系，包括前三角洲亚相、三角洲前缘亚相、三角洲平原亚相、曲流河相和下切谷沉积等。

The deltas differ from typical deltaic model.Deltaic front subaqueous distributary channel sand bodies and deltaic plain distributary channel sand bodies are the skeleton sand bodies of meandering stream-shallow sea delta and braided streain-shallow lake delta respectively but not tranditional deltaic front river mouth sand bars.

这两类三角洲与经典的三角洲模式不同的是，三角洲前缘水下分流河道砂体和三角洲平原分流河道砂体分别构成了曲流河浅水海相三角洲和网状河浅水湖泊三角洲的骨架砂体，而不是传统认为的三角洲前缘河口砂坝。

ABSTRACT The Yellow River delta located in the land and sea interaction zone and is being formed with the coaction of the River and Bohai sea. The three parts of the whole delta, i. e. the delta plain, tidal zone and submerged delta, are in different dynamic environments. The delta plain is controlled by the land surface processes. The tidal zone is under the coaction of the river and the sea.

黄河三角洲处于海陆交错地带，是河流与海洋因素共同作用的堆积体，从陆上三角洲平原到潮间带直至水下三角洲受不同动力因素的作用，陆上三角洲平原主要受陆地表层过程的影响；潮间带受陆、海动力的共同作用，而水下三角洲主要受海洋动力的作用。

In the basis of the facies markers and facies analysis of principle, there are mainly river、delta and lake depositional sysytems in Upper Triassic of Nanniwan field,in which all kinds of difference sedimentary subfacies and sedimentary microfacies are distinguished, such as meandering river、delta plain、delta front、submerged distributary river course、frontal sheet sand and so on.

利用收集到的各种相标志和相分析原则，对研究区的沉积相进行了比较细致的研究，将南泥湾探区上三叠统分为河流、三角洲、湖泊三种沉积体系，并在各沉积体系中细划出曲流河、三角洲平原、三角洲前缘、浅湖等沉积亚相和水下分流河道、河口坝、前缘席状砂等沉积微相。

The main target zone of the CARACOLES area in eastern Venezuela basin is a series of delta facies sedimentation in ocean-land transitional environment.

东委内瑞拉盆地卡拉高莱斯地区主要目的层为一套海陆过渡环境的三角洲相沉积，三角洲平原河道、三角洲前缘水下分流河道、河口坝及决口扇构成区内主要沉积骨架砂体，各种微相砂体单层厚度薄，分布面积小，在地震剖面上无法直接识别。

The Olmos Formation in the Gold River North field is characterized by a shelf-edge deltaic system, from which five types of depositional systems are identified:(1) fluvial plain, which is characterized by fluvial channels, crevasse splays, and swales;(2) deltaic plain, which consists of distributary channels, levees, and crevasse splays;(3) deltaic-front mouth bars and sheet sands;(4) prodelta, which is composed of silty sediments; and (5) incised valleys, which were formed during subsequent lowstand erosion on exposed deltaic sediments.

美国南得克萨斯地区Webb县Gold River North油田上白垩统Olmos组钻井资料较少，采用地震沉积学方法对其分析，可以识别出一套完整的三角洲体系，其中包括前三角洲亚相、三角洲前缘亚相、三角洲平原亚相、曲流河相和下切谷沉积等，其中河道砂、河口砂坝和下切谷沉积物是有利的储层。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
