油田开发进入中、后期,储层含水量越来越高,给油田的稳产带来很大的威胁;为了进一步提高储层采收率,需要提供更加精细的地质模型,通常利用储层地质知识库进行建模约束.GoogleEarth软件提供了一种定量测量河道及宏观观察河道流向的功能.通过对内蒙古海拉尔河25个分辨清晰的点坝砂体相关参数测量,分析得到了海拉尔河点坝长度与点坝宽度、点坝长度与河道满岸宽度、单一曲流带宽度与河道满岸宽度的关系方程,分别呈现正相关关系.但在同一地区,不同曲率下的相关程度又存在一定差别.%As oilfields enter middle and later stage,reservoir water increasingly rises so as to make stable yield more difficult.In order to improve reservoir recovery ratio,a more refined geological model needs to be provided.Usually,a constraint modeling is carried out by using geological knowledge base of reservoir.Google Earth software provides a function to quantitatively measure water channel to observe river flow direction.According to the measurement and analysis on relevant parameters of 25 clearly distinguished point bar sand bodies in Hailar River of Inner Mongolia,we can obtain the relation equation between point bar length and point bar width of Hailar River.There are between point bar length and water channel bankfull width,including single meander belt width and water channel bankfull width.A study result shows that a positive correlation is available respectively in point bar length and point bar width of Hailar River,including point bar length,water channel bankfull width in single meander belt width and water channel bankfull width.The correlation will have its different degree under different curvatures in the same region.
