【摘要】 大庆油田已进入特高含水期开发阶段,大部分主力油层已经投入注聚开发,相当部分主力油层注聚接近结束,可采储量不断减少,在这种情况下,二类油层的三次采油成为保证持续稳产的一个重要开发方向。本课题从喇嘛甸油田、萨中油田开辟的两个“二三结合”试验区出发,通过对大量现场资料进行整理,对储层的构造特征、流体性质、发育状况、沉积特征、剩余油分布进行对比分析,总结二类油层地质特点,给出二类油层潜力,并综合多方面资料的分析,确定试验对象、合理井距和井网部署原则,给出方案编制过程,在加密新井投产后,着重分析了试验区水驱阶段的动态指标变化情况,并通过采油速度、产量构成等情况总结了“二三结合”在保持油田接替稳产、控制产量下降含水上升方面所发挥的作用,为了通过补充新钻井各方面资料,进一步深入认识试验区储层情况、深入评价开发状况以及对今后的开发情况进行预测,在喇嘛甸试验区选取典型区块进行精细地质建模和数值模拟,通过多套数据相结合、沉积相控制属性的方法建立地质模型,在油水井动态数据的基础上充分考虑封堵、补孔、压裂等措施,建立精细动态模型,在做好储量拟合、历史拟合的基础上,对目前各细分单元动用情况作了分析,对不同开发方式作了预测对比,明确了水驱调整在“二三结合”过程中提高采收率的贡献,为“二三结合”下一步调整提供技术支持。更多还原

【Abstract】 Daqing oilfield has entered the development stage of extra high water cut.majority mainlayers have been developed by polymer and some have accessed end.the tertiary development that focus sub-mainlayers became the important method of guaranteeing oilfield steady production.Basing on the testfields of Lamadian oilfield and Sazhong oilfield,author contrasted and analysed the structure,reservoir liquid,sand, sediment pattern and remaining oil, summarized character of sub-mainlayer geology and exploitation potential,confirm aim layer,well distance,method well spacing.After new well put into production,author analysed the change of production index and summarized the effect of second tertiary combin in keeping oilfield steady production,preventing decline of production and rise of water cut.author made fine model and simulation in Lamadian test region for deeply evaluating development effection deeply catching reservoir state and predicting the data of development.author made geologic model through several data system and face controlling technic and made simulate model through production data layer shut data perforation data and acidulation data.base on de work of matching of reserve and history,author analysed the oil recovery in every layer, predicted and compared several plans,confirmed the effect of waterflood in second tertiary combined and offer technic support for next step.更多还原
