基于最小二乘法的注水管网摩阻因数反演
摘要
Abstract
In oilfield water-injection network, pipe friction factors are important parameters. Oil field water-injection network has been built for a long time, so the pipe friction factors have changed, a lot, and we need to correct friction factors. In this paper the least squares model of friction factor inversion under single operating mode is established. According to the model's features, an effective numerical method is given by using singular value decomposition and loss-rank least squares model. Finally, the model on the ideal pipe network is solved, and rationality of the model and algorithm is certified.关键词
