三角洲

The analysis of the high quality sand-body trap's characteristics suggests that large-scale traps include single large-sized sand-body trap and several overlaying small-sized lithological traps; furthersome reservoir facies involve fan delta, braided river delta and sublacustrine fan; the hydrocarbon enrichment usually forms in favorable reservoirs.

Based on the existing data of the Yangtze delta area, a preparatory simulative experiment have been done by the model on the sea-land change course in Yangtze delta area since l0000aBP, and a good simulative effect are obvious from the hypsometric paleotopographic map and 3D color shaded-relief map which exported from the model. That provides a visual scene to analyze and discuss the Yangtze delta evolution, coastline shifting, even the relationship between the ancient civilizations migration and environments.

利用海面—地面系统的模拟模型，对长江三角洲一万年以来的海面—地面变化过程进行了重构和反演，获得了一套该地区的古地貌和海陆关系演变图，它包括等高线、晕渲图、三维图等三种不同表现形式的地形图，为分析讨论长江三角洲地区地貌发育、岸线变迁乃至古代文明的迁徙和兴衰与环境的关系提供了很直观的场景。

Researches indicate: the main depositional sub-facies sedimentary system of Sanjianfang Formation in Wenmi reservoir of Turpan-Hami basin are braided stream delta front, prodelta of braided stream and infralittoral turbidite fan.

研究认为：三间房组沉积体系的主体亚相为辫状河三角洲前缘（分为5种微相）、前辫状河三角洲以及带供给水道的远岸浊积扇体（分为3种微相）；影响储集层参数及油气产能的主要因素是沉积微相类型。

In this paper, the characteristics of reservoir of reservoir of delta frontal sub-faces of PI Formation in the south of Xingshugang are studied with the data of dense well pattern and rock-mineral identification. The delta frontal sub-faces can be divided into lobate delta frontal sub-faces, branched delta frontal sub- faces and sheeted delta frontal sub-faces. The genetic types of sand bodies in different sedimentary envivonments are analyzed in detail, and the distribution and space-matching relationship of different sand bodies are studied. The micro-pore structure type is studied on the base of the thin section analysis, so the reservoir heterogeneity is studied including plane heterogeneity, interlayer heterogeneity, in-layer heterogeneity and microcosmic characteristic.

利用密井网、岩矿鉴定等资料对杏南地区葡I油层组前缘亚相储层进行研究，将三角洲前缘细分为枝状、朵状、席状3种类型，详细分析了不同沉积环境下砂体的成因类型，描述了不同类型砂体在平面上、空间上的展布特征和组合关系，不同砂体内部性质的差异以及砂体内部微观孔隙结构的类型和分布特征，从平面、层间、层内以及微观特征等方面研究了三角洲前缘储层的非均质性。
