The oilfield water injection network had the characteristic which was the value of pipe roughness general between 0.013 and 0.018, so the method of adjustable parameter tree is proposed to calibration pipe friction coefficient, the method which makes adjusted node flow similar to given node flow by calibrating pipe roughness coefficient, could calibrate pipe friction coefficient. In this article, an idea network had been tested, and the result was preferable, so the adjusting parameter tree was effective.
