摘要
在塔河碎屑岩注水井压力降落试井中,通过非线性自动拟合法利用碎屑岩注水多区复合油藏模型求出地层渗透率、表皮因数、井筒储集系数以及水驱前缘半径,计算剩余油饱和度分布。利用所编制的实用软件,通过塔河油田4口井实例分析与常规解释方法对比验证了该方法的解释结果具有可靠性与优越性。
In the falling-off test in clastic water injection wells of Tahe Oilfield,nonlinear parameter estimation method was used in well test to obtain formation permeability,skin factor,wellbore storage coefficient,and water drive front radius,obtain the distribution of remaining-oil saturation.The developed application software is used in 4wells in Tahe Oilfield.The field application demonstrates that the result of the method is reliable and advanced.
