本次老区新井产能预测方法采用以下几个方面来综合预测新井产能 :1设计新井有效厚度 h:根据分单元水淹图和油藏数值模拟结果来确定部署新井的剩余油有效厚度 h;2产液指数 J:根据相渗曲线、含水—含水饱和度关系曲线 ,计算出采液指数 J;3新井含水确定 fw:根据邻井的对应层生产时的含水来确定新井含水 fw;4生产压差 P:根据监测资料求生产压差 P;5日产液 QL:QL=J× h× P;6日产油 QO:QO=QL×fw。
The new well productivity prediction method of the old area uses the following aspects to comprehensively predict the productivity of the new well: 1 Design the effective thickness of the new well h: Determine the remaining oil effective thickness h of the new well according to the sub-unit water flooding diagram and reservoir numerical simulation results; Liquid index J: According to the phase-permeable curve, water-water saturation curve to calculate the fluid production index J; 3 Determination of new well water fw: According to the adjacent wells of the corresponding production of water to determine the new wells water fw; P: According to the monitoring data to find the production pressure difference P; 5 liquid production QL: QL = J × h × P; 6th oil production QO: QO = QL × fw.
