摘要
通过数值模拟和灰色关联方法,研究含隔夹层底水油藏注水开发受到的影响。分析了原油黏度、隔夹层面积、隔夹层垂向位置等主要影响因素,确定了合理的转注时机、注采比及采液强度。通过数模预测,对A油藏4口油井进行转注调整,预测结果显示采出程度有所提高,注水开发效果预期良好。
With the help of the methods of numerical simulation and grey correlation,the influencing factors of water injection on the development of bottom water reservoir with interlayer are studied.The results show that the viscosity,the area of interlayer,and the vertical position of interlayer are the main factors,and the reasonable injection timing,injection production ratio and intensity of liquid production are determined.Based on prediction with digital analog,by transferring four wells in A Reservoir,the recovery has increased,and the development effect of the oilfield is improved.
