摘要
针对新场气田上沙气藏致密低渗储层的地质特征,利用随机模拟方法建立储层参数定量三维地质模型,应用网格粗化技术由地质模型生成数值模拟应用模型,最后,通过数值模拟中的历史拟合、参数调整、完善地质模型,优化气藏地质认识,指导开发方案调整。生产实际表明:基于地质模型进行致密低渗气藏研究能较好解决石油地质研究和气藏工程的衔接问题,能从动态和静态角度研究气藏,从而为气藏开发的动态预测和方案优化奠定基础。
Aimed at the geology characteristics of tight low permeability gas reservoir in Xinchang Gas Field, this paper establishes the 31） geology model for reservoir parameter quantitativeness by using stochastic modeling method. Using grid coarsening technology, it also establishes the model which can be generated by geology model and used by numerical simulation. Through the history matching and parameter adjusting, the geology model and knowledge of gas reservoir can be improved in order to guide the development plan adjustment. The production practice shows that the research of tight low permeability reservoir based on reservoir modeling can solve the connection problem of geology study and gas reservoir engineering, and can also research the gas reservoir from the angle of dynamic and static state, which lays foundation for performance predication and project optimization.
