在前人岩相古地理研究的基础上,根据三级层序的两大特征——"空间上相序的有序性和时间上环境变化的同步性",并考虑到地层记录中的两种相变面和两种穿时性――"静态相变面及其相变面穿时、动态相变面及其间断面穿时",建立研究区域志留系的层序地层格架,并在此基础上从沉积物的时间演化序列和沉积相的空间展布形式入手,恢复其古地理背景。

The rate of subsidence has been decreasing from area near vertex of delta to the coastal zone and some place is even rising, particularly in the early formed area. What is the different in the coastal is that the rate of subsidence is still high and can sustain a long time. This is because the land subsidence in the delta is mainly caused by the consolidation of sediments if there is no human activity. Especially in the newly formed area, Qingshuigou sub-delta, the rate of subsidence was more than 50 mm/a in the begining and now is still higher than 10 mm/a. When the newly sediments discharged by the Yellow River landed on the subaquatic delta, its load can drive the concolidation of the silt, which is on the surface of the Bohai seafloor. The rate of consolidation of the silt will be decreasing quickly in the first years, but still a long time in the later time with a slow rate.
研究结果表明:现代黄河三角洲在以宁海为顶点的河口扇形区域,近期均经历了不同程度的地表下沉过程,但是随区域地理位置和时间的不同,地表变化空间差异性比较明显;三角洲顶点附近区域的下沉速率自上世纪末开始逐渐减小,后期甚至出现轻微的抬升;滨海沿岸附近地区的地表形变特征相对比较复杂,各期叶瓣相互叠置及其各类沉积物的不均匀分配,使由沉积物自然固结压实引起的地表形变具有显著的空间差异;目前,除清水沟流路叶瓣表现为快速沉降以外,其它滨海沿岸区基本上都表现为微弱的下沉。

The Yushulin oilfield is located in eastern slope of Sanzhao seg of central sag zone in the northern part of Songliao basin. Its main oil-producing formations are Fuyu and Yangdachengzi oil layers of mesozoic group cretaceous. Its reservoir is fluvial facies sediment. Main sandstone is positive circle channel sandstone with calcium in the beneath, and microelectrode curve is box distribution function. Its secondary oil-producing formation is Yaoyi part of Putaohua oil layer. Its reservoir is delta front sediment. Main sandstone is subaquatic distributary channel sandstone, and microelectrode curve is box distribution function.

近十年来,作为有现代化测井技术、反射法地震勘探技术和计算机数据处理方法等参与的盆地油气勘探已为这一工作提供了新的信息并增加了新的分析内容,以地表露头剖面和钻井岩蕊观察为基础、进而在区域上作出推断的纯定性传统沉积相分析方法已经不适应当今油气勘探的要求,因此,如何充分利用地质、测井、地震及其他方法提供的大量信息,用综合化、程序化乃至定量化的方法进行盆地沉积相分析和其他研究近年来受到石油地质学家们的普遍关注。
