摘要
对于高含水时期的油藏,注采结构直接关系到油田的开发效果。目前阶段,利用人工设计注采调整方案准确性低,难以寻找最优解,而传统数值模拟则多是针对规则井网进行注采调整,存在网格维数高、优化梯度求解复杂等缺点。以厄瓜多尔A油藏为例,利用井间连通性理论结合优化算法对高含水油田不规则井网进行注采优化调整,可以在实现自动制定转注井位及时机的同时求解注采参数,并在厄瓜多尔A油藏进行实际应用,能有效改善油田开发,完善注采结构。
For reservoirs with high water cut,the development effect of oilfield is directly related to injection-production structure. At present,it is difficult to find the optimal solution by using artificial to design the injection-production scheme. While the traditional numerical simulation method is mostly aimed at regular well pattern to adjust the injection-production structure which has the disadvantages such as high grid dimension and complicated optimization of gradient. Therefore,the interwell connectivity theory combined with the production optimization was used to optimize the injection and production of the irregular well pattern for high water cut oilfield which can solve the injection-production parameters and injection well location and injection time at the same time. The practical application of a reservoir in Ecuador can effectively improve the injection-production structure and oilfield development.
