摘要
秦皇岛32 - 6南区原油粘度高密度大,具有常规稠油的特点,目前生产状况极不乐观。本文采用数值模拟方法,对边底水油藏进行了垂向渗透率及开采速度敏感性分析,从储量合理动用、先进井型确定、合理产能设计等几个方面进行了虚拟开发研究。结果表明,秦皇岛32 - 6油田南区采用水平井开发可有效提高采出程度,改善开发效果。开发过程中先动边水主力油藏、然后动用边水构造岩性油藏、最后动用底水油藏可取得最佳开发效果。通过虚拟开发。
The south region of Qinhuangdao32--6 is conventional heavy oil reservoir with high viscosity and big density. The condition of production is very pessimistic at present. The sensitivity of vertical direction permeability and production rate are analyzed for oil reservoir with edge and bottom water by numerical simulation. Reasonable reserve producing, advanced well type determined and reasonable production rate design and so on are studied. The result indicate that using horizontal well can enhance recovery factor and improve development efficiency in 32--6 south region of qinhuangdao. Best production efficiency can be obtained through first producing main oil reservoir with edge water, then structural lithologie reservoir with edge water, finally oil reservoir with bottom water during recovery. A thought of a fewer well and higher production are put forward through virtual producing.
