| 中文摘要: |
| 考虑水平井的分段采油,研究了封闭油藏、定压油藏、底水油藏三类油藏的渗流模型,建立了以水平段每段长度和中心点位置为研究对象的新优化模型,并对水平井分段数、每一段的长度及距离跟端位置等待优化的问题利用遗传算法最终给出了一套具有实际应用价值的最优分段方案。 |
| 英文摘要: |
| Based on the separated production scheme of horizontal well, the pressuer transient performance of horizontal wells has been researched, including three boundaries: no flow boundary, constant pressure boundary, and bottom water-drive boundary. And three new optimization models that takeing the length and location of horizontal intervals as research objects are built. These new optimization models are solved by using genetic algorithm. Then a practical optimum distribution for intervals was given. The change rules of production are discussed when the parameters of the models change. The plots of type curves are given, and the results have important practical significance for the separated production scheme of horizontal well. |
