摘　　要：XJ油田为强边底水砂岩油藏,边底水能量充足,属于高孔高渗储层,采出程度高,预测精度误差大。针对海相强边底水砂岩油藏目前水驱曲线预测存在的问题,以生产动态资料分析油藏驱替特征出发,研究油井水淹类型影响因素,并从地质因素和驱替特征说明水驱曲线的适应性。在前人对于水驱曲线预测方法研究的基础上,结合强边底水油藏的驱替特征以及生产特点,重点研究水驱特征曲线的适应性与驱替特征的关系、修正目前水驱特征曲线以适应预测极限采收率,并编制相应的计算模块,从水淹规律、适用性分析、水驱曲线修正三个方面总结强边底水砂岩油藏水驱曲线预测极限采收率的油藏工程方法。XJ oilfield is a strong edge and bottom water sandstone reservoir with sufficient edge and bottom water energy.It belongs to a high porosity and high permeability reservoir with high recovery degree and large prediction accuracy error.Aiming at the problems existing in the prediction of water drive curve of marine strong edge and bottom water sandstone reservoir,starting from the analysis of reservoir displacement characteristics from production performance data,the influencing factors of oil well water flooding type are studied,and the adaptability of water drive curve is explained from geological factors and displacement charcteristics.Based on the previous research on the prediction method of water drive curve,combined with the displacement characteristics and production characteristics of strong edge and bottom water reservoir,this paper focuses on the relationship between the adaptability of water drive characteristic curve and displacement characteristics,modifies the current water drive characteristic curve to adapt to the prediction of ultimate recovery,and compiles the corresponding calculation module to analyze the water flooding law,applicability.From three aspects of water drive curve correction,this paper summarizes the reservoir engineering method of predicting ultimate recovery by water drive curve in sandstone reservoir with strong edge and bottom water.
