摘要
在Fetkovich方法基础上,结合单相流和油气两相流动特点,推导出基于Fetkovich方法的综合IPR方法,并给出了如何通过测试数据获得采油指数的计算方法;再由按含水率取纯油IPR曲线和水IPR曲线的加权平均,推导出了基于Fetkovich方法的三相流的采液指数计算方法和某一产量下流压计算方法。通过实例进行验证,说明了导出方法具有一定可行性。
On the basis of the Fetkovich method,combing with the flow characteristics of single-phase flow and two-phase flow,the composite IPR method is derived based on Fetkovich method,and the calculation method of the oil production index on the basis of test data is given;according to the weighted average by water cut from pure oil IPR curve and IPR curve of water,the calculation method of liquid production index of three-phase flow and the flow pressure of well bottom in an certain production rate are derived on the basis of Fetkovich method,finally the feasibility of the two methods is proved by the given examples.
