强底水礁灰岩油藏水驱采收率表征模型
|
摘要
为了对海上强底水礁灰岩L油藏水驱采收率进行快速预测,通过对油藏开发过程中的地质参数、流体参数和工程参数进行分析总结,建立了包含影响开发效果各个因素的机理模型,并结合数值模拟研究,获取了采收率与各影响因素间的函数关系,确定了影响油藏水驱采收率的主控因素。在此基础上,运用正交实验设计与多元非线性回归理论,建立了礁灰岩油藏水平井开发水驱采收率定量表征模型。实例应用结果表明,该采收率表征模型可用于强底水水平井开发条件下的礁灰岩油藏采收率快速领测,预测结果精度较高,误差小。
To realize rapid prediction of the recovery rate of offshore strong bottom water drive reef limestone reservoir L,a model for simulating the mechanisms of the various factors affecting the reservoir exploitation was developed. The model was developed by reviewing and analyzing the geological, fluid, and engineering parameters associated with the reservoir exploitation process. The functional relationships between the recovery rate and the various influencing factors were then determined on the basis of the model as well as a numerical simulation study, thereby yielding a list of the major factors affecting the recovery rate of the water drive reservoir. Through this approach,a model was then developed for quantitatively representing the recovery rate of water drive reef limestone reservoirs, by employing an orthogonal experiment design and multiple nonlinear regression theory. Field application results showed that the recovery rate model was capable of rapidly predicting the recovery rate of strong bottom water drive reef limestone reservoirs exploited using horizontal wells, with high accuracy and small error.
