根据Petrobras方法,结合溶解气驱油藏水平井油气两相无因次IPR(流入动态)方程和单相流动时产液指数,建立油气水三相流入动态方程,根据实际生产数据计算并绘制IPR曲线。
By Petrobras method,the oil-gas-water three-phase flow dynamic equation of horizontal wells was set up,based on IPR equation of solution gas drive oil-gas two phase and the constant produced fluid index for single phase flow. The oil-gas-water three-phase flow dynamic equation could help us calculate and draw the IPR curve according to the actual production data.
