本文结合五台油田的油藏类型、开发历史和开发现状,从地质条件和开发特点出发,系统分析储层非均质性、润湿性、韵律性砂岩不同部位注水开发及注采井数比等因素对水驱效率的影响。
应用精细地质描述、新井多功能解释、注入产出剖面分析、动态资料统计及油藏数值模拟等多种方法对不同类型油藏进行了剩余油分布研究,对各类油藏下一步提高采收率的潜力和挖潜方向进行了分析评价,提出了细分开发调整、周期注水、堵水调剖、加密调整等提高油藏水驱采收率的配套技术方法。
尤其是针对五台油田广泛发育构造复杂、油层多、层间差异大、储量丰度高的复杂断块油藏,该类油藏由于构造复杂、沉积类型多样,对油藏地质体的认识难以一次到位,开发初期层系往往划分较粗,随着开发时间延长,层间层内矛盾日益突出,相对中低渗透层段吸水能力差,潜力得不到发挥。针对这一开发矛盾,研究了渗透率、主力层数、油层厚度、原油性质等参数对层间干扰的影响,开展了层状断块油藏高含水期细分开发可行性研究。在此基础上从渗透率级差、主力油层数、原油性质差异、含油面积与地质储量等方面开展了开发层系划分标准的研究,形成了多油层复杂断块油藏高含水期细分开发层系、提高水驱采收率的配套开发技术。先后在辛47、辛50等断块进行了细分开发调整的探索和实践,取得了显著效果,其中典型单元辛47断块采收率从36%提高到40%,增加可采储量30x104t。

关键词 采收率,细分开发,间歇注水,加密调整
