沉积微相约束下的储层物性参数建模研究
|
摘要
在地震、测井、地质原始资料综合解释等基础上,以胜坨油田坨28块沙二段Es42砂组为研究对象,应用Petrel储层建模软件,建立研究区的构造模型和沉积微相模型,并采用随机模拟的方法,以沉积微相为约束条件,对储层进行井间参数预测,进而得到研究区的储层属性模型。通过对比和检验相控与非相控模型,可知相控建模技术实现储集层属性分布和沉积微相的对应性,能真实地反映平面上和纵向上储层的非均质特性和连通性展布规律,与油藏实际地质认识相佐证,证实了相控建模的合理性和科学性,为油藏后续开发方案的设计提供指导。
On the basis of the comprehensive explanation of seismic,logging,and geological original materials,the Es42 of 28 block of Shengtuo Oilfield was taken as the research object.The Petrel reservoir modeling software was used to establish the structure and sedimentary microfacies models.Moreover,under the restriction of sedimentary microfacies,stochastic simulation was applied to predict reservoir parameter between wells,and the reservoir property model was finally established.By comparing the phased and non-phased models,it is found that phased modeling technology could realize the correspondence between reservoir property and distribution of sedimentary microfacies.The results could also factually reflect the vertical and lateral heterogeneous and connectivity of reservoirs.Verified by the real reservoir geological understanding,it confirmed the rationality and scientific nature of the phased modeling,which can provide guidance to the development design in future.
