ECLIPSE数值模拟技术在F70区块的应用

Application of ECLIPSE numerical simulation technique in F70 area

为了能更好地为化学驱开发方案优化提供技术服务,利用ECLIPSE数值模拟软件对扶余油田F70区块开展了数值模拟工作。在油藏描述的基础上,进行网格划分,建立F70区块精细地质模型,包扩构造模型、砂体模型、孔隙度模型、渗透率模型及净毛比模型;根据生产历史资料建立动态模型;通过对油藏模型参数的分析,建立油藏数值模拟模型,应用ECLIPSE数值模拟软件对区块地质储量及各小层地质储量进行拟合,并结合油水井生产动态数据进行水驱历史拟合。根据拟合结果可以看出无论是全区累计产油量和日产油量还是单井产油量和含水率与实际生产数据相比都控制在相对误差范围内,做到了很好的一致性,能够真实地再现油藏的开发历程,为后期开展化学驱数值模拟奠定良好基础。

In order to support technique service of development scheme optimized on chemical flooding,using the ECLIPSE numerical simulation software to simulating work on F70 area in FuYu oilfield. Grid classification is made and detailed geology model is established on the basis of reservoir characterization,including conformation model ,sandstone model,poristy model,permeability model and net gross model.A dynamic model is established according to historical production data.A reservoir numerical simulation model is established by analyzing the parameters of reservoir model, and ECLIPSE simulation software is used to conduct a reserves study on total area and every layer. A history match of water flood is made by dynamic production data of oil and water well. According to the matching results, the relativity error are well and consistent with historical production data,either FOPT and FOPR or WOPR and WWCT. It can veritably reappearance the course of oilfield development and lay the foundation of numerical simulation on chemical flood later.
