基于响应面设计方法的海上油田注聚段塞优化研究

Research on Response Surface Design Optimization of Polymer Injection Slug in Offshore Oilfield

采用正交试验设计方法对海上油田先导试验井组注聚段塞组合方式进行优化,提出适合该区域的最优注聚段塞方案。采用响应面设计方法对此正交试验设计最优方案进行再优化。建立响应面回归方程,以综合指标为响应目标函数,求得方程最优解,得到再优化后的注聚段塞组合新方案。

This thesis adopts orthogonal experimental design method to optimize the slug combinations for offshore oilfield polymer injection in pilot test well group in order to get the optimal polymer injection slug solution. The response surface design program was used to re -optimize the above optimal solution. By setting up response surface regression equation, we obtained the optimal solution of the equation with integrated indicator as response objective function. And finaly re -optimized segment polymer injection combination scheme was realized.
