摘要
为解决油田大型注水系统建模和制定优化运行方案，建立高精度的数学模型，提出了多步广义梯度法和多层曲线拟合的建模方法，综合运用了大系统理论、人工智能和模糊数学方法。对系统进行了多层分解，并建立了系统的知识库。通过图搜索技术使制定的运行方案得到初步确定。由大系统协调原理使运行方案得到完全确定。该方案在大庆采油六厂实施后，既达到地质配注要求，又实现了节能目标。
A multi-stepped,generalized gradient method and a new modelling method with multi-curve fitting are put forward.New optimizatiom methods of flood patterns are given on thebasis of large system theory,artificial intelligence and fuzzy mathematics.We can makemultiple decompositions and build data base for the systems according to the theories above.The optimal running schemes can be established by graph search techniques and large systemccordination methods.It is proved that the schemesare advanced,correct and effective infield application in Daqing OiI PIant No.6.
