目的：探寻垂直井开采厚油层最终采收率随各影响因素的变化趋势。方法：利用正交试验设计技术，对数模结果进行直观分析和方差分析，排列出各因素对最终采收率影响效果主次顺序，最后根据模拟方案计算结果进行多元回归。结果：得到计算最终采收率的多元相关公式。结论：在生产、地质、流体参数已知的条件下，可定量确定厚油层最终采收率，为后期挖潜奠定基础。
Objective: To explore the trend of the ultimate recovery of the thick oil reservoir with the influence of various influencing factors. Methods: Orthogonal experimental design techniques were used to conduct direct analysis and analysis of variance on the results of numerical simulation. The order of the primary and secondary factors affecting the ultimate recovery rate was listed. Finally, the regression results were calculated according to the results of simulation. Results: A multivariate correlation formula for calculating the ultimate recovery was obtained. Conclusion: Under the conditions of known production, geological and fluid parameters, the final recovery rate of thick oil layer can be quantitatively determined, which lays the foundation for tapping potential in the later stage.
