沉积作用

On the basis of plan form and crosscutting relationship of the faults, two kinds of tectonic systems were developed in Wu-Xia area, one was strike north-east, and another was strike east-west, the first was developed early and control the structural framework of Wu-Xia area, after that three times longitudinal compress action was happed. According to the intensity of tectonic deformation, The Wu-xia faulted zone from north to south can be divided into the thrust faulted belt, the fault fold belt and the monocline belt. from east to west have three regulatory faults, Wuerhe fault fold belt, Wuxia thrust faulted belt and Xiahong fault fold belt. Base on that 9 secondary structural unit can be divided.Structural accommodation zone and the distribution of reservoir strata have intimate business connection. Usually, Structural accommodation zone was the source zone of arenaceous sediment. The Wu-xia faulted zone have 3 kinds of structural accommodation, concordant approach, concordant overlap and concordant colinearity.

首先研究本区的构造特征，根据断裂的平面形态及相互切割关系，乌夏地区发育两种构造体系：北东向构造体系和近东西向构造体系，前者形成早，控制了该区的构造格局，晚期有3次近南北向挤压作用叠加；乌夏地区南北根据构造变形的强度不同分为冲断带、断褶带、单斜带，东西由于横向调节断层的存在分为乌尔禾断褶区、乌-夏冲断区和夏-红断褶区，进一步划分为九个次级单元；构造调节带与储集层的分布关系密切，通常是大量富砂质沉积的源区，乌夏地区发育三种类型的构造调节带：同向接近型、同向叠覆型和同向共线型。

Early diagenesis has broad and bright prospects not only in theory but also in application, and three future trends are predicted. First, the area of early diagenesis study will be enlarged widely to lake, delta, soil. Then, the stable or nonstable one-dimensional, two-dimensional or three-dimensional multi-layer early diagenesis models will be established, and the methods and theoretical achievements of early diagenesis will be widely applied in environmental sedimentology to supervise and treat environment pollution.
