【摘要】：水平井开发底水油藏面临最大的问题就是底水脊进,底水油藏见水后的生产动态目前没有合适的解析解进行描述。目前研究中存在平均水锥高度计算方法、模型简化过程中部分参数被忽略等方面的问题,利用Matlab编程的方法,结合油田实际生产井的静动态参数,通过比较水油比与平均水锥高度关系曲线的拟合情况,完善了文献中预测模型,改善后的预测模型更加符合油田实际生产情况。利用该模型,可以较快的拟合单井的含水率随累产油的生产动态曲线,可计算单井的技术可采储量。同时,利用筛选的"标准井"的实际参数拟合了模型中修正项的各项参数,通过该模型可以确定出底水油藏不同流体类型的油柱高度下限值,为油田进一步的开发调整提供指导。
[Abstract]:The biggest problem in the development of horizontal well bottom water reservoir is the bottom water ridge advance. At present, there is no suitable analytical solution to describe the production performance of bottom water reservoir. At present, there are some problems in the calculation method of average water cone height and the neglect of some parameters in the process of model simplification. The static and dynamic parameters of oil field production wells are combined with the method of Matlab programming. By comparing the curve fitting between water / oil ratio and average water cone height, the prediction model in literature is improved, and the improved prediction model is more in line with the actual production situation of oil field. By using this model, the production performance curve of water cut of single well with cumulative oil production can be fitted quickly, and the technical recoverable reserves of single well can be calculated. At the same time, the parameters of the modified term in the model are fitted by the actual parameters of the "standard well", and the lower limit value of the oil column height of different fluid types in the bottom water reservoir can be determined by the model. To provide guidance for further development and adjustment of oil fields.
