At the late period of water injection in multi layer heterogeneous river-delta depositional system of Daqing oilfield, liquids production of partial blocks and certain well fields is high, water cut is high, producing performance is not balanced, and swept volume of conventional water injection can not be improved.
针对大庆油田河流—三角洲沉积体系的多油层、非均质注水开采的高含水后期所暴露出部分区块和个别井区的产液量高、含水高、动用状况不均衡、常规注水难以再扩大波及体积等问题,应用数值模拟研究了具体开发区块周期注水的合理时机和周期。
Based on fine de-scription of residual oil distribution,well pattern adjust-ment and pulse water injection were performed in Block7in Gudong oilfield to enlarge swept volume,to tap residual oil potential in low permeability zone,to reduce the area of region of bypassed oil and to improve utiliza-tion fact.
在孤东油田七区西63+4单元剩余油分布精细描述的基础上,通过井网调整及脉冲注水,在扩大注水波及体积、挖掘低渗区剩余油潜力、减少死油区、提高注水利用率方面进行了系统阐述,并先后进行了现场实施,取得了明显的增油效果。
In this way, retained oil can be mobilized, the sweeping volume and use factor of injected water can be raised.
周期注水是利用现有的井网,周期性地提高和降低注水压力的办法,在油层内产生不稳定压降,使层内不同渗透率区域之间产生相应的液体交换渗流,使滞留状态的原油动用起来,扩大注入水的波及体积,提高注入水的利用率。
north 1 6 inspection well 27 for inspecting water flooding result and north 1 6 inspection well 26 for inspecting polymer flooding result,this paper deems that the polymer flooding only changes mobility ratio between oil and water,enlarge a sweeping volume and improves oil displacement efficiency.
通过对相距只有 30 m的检查水驱效果的北 1- 6 -检 2 7井与检查聚合物驱效果的 1- 6 -检 2 6井驱替效果的对比分析 ,认为聚合物驱只是改变了油水流度比 ,扩大波及体积 ,进而提高了驱油效果。
