油藏模拟技术在渤海油田的应用

THE APPLICATION OF RESERVOIR SIMULATION TECHNIQUE IN BOHAI OILFIELD

油田开发和生产中重大问题的决策，主要靠全体油藏模型来解决。单井径向、剖面和井组模型做为辅助模型，可解决全体油藏模型难以解决和无法解决的问题。要使油藏模拟结果同油田生产实际相符合，关键是建立一个同油田地质模式相适应的油藏模型和对油田进行生产历史拟合。搞好油藏模拟生产历史拟合的关键是正确使用拟函数和调整模型的输入参数。在油藏模拟中对一些具有不确定性的重要输入参数和限制条件，要进行敏感性分析。通过实例说明油田开发和生产中的许多问题，有可能通过油藏模拟研究得到合理解决。

Decisions on major problems in developing and producting of an oil field are mainly made by using the whole of the models of single well diameter,cross section and well group,which can solve the difficult problems. To make the results of a reservoir simulation study fit into the productive situation of an oil field,it is the key to build a model of the reservoir fitting to geological patterns of the oil field and match it with the productive history of the oil field. To be successful in matching a reservoir simulation with the productive history of an oil field, it is the key to use correct psedofunctions and to adjust the input parameters of the model of a reservoir. For some of the in-definitive important input parameters and restrictive conditions in a reservoir simulation,their sen-sibilitymust be analysed. This paper also illustrates that it is possible for many problems in developing and producting of an oil field to be solved reasonably by reservoir simulation study.
