摘要:

针对注水开发的多层砂岩油藏分层动态分析难度大等问题,在常规井层开发指标计算基础上,结合动、静态劈分方法,综合考虑渗透率、孔隙度、地层系数、含水饱和度、位置系数、措施系数及注水量系数,提出了一种既可将油、水井作为统一整体,又可对小层、方向流动分量开发指标进行定量计算的体现渗流力学本质的方法。用大庆油田N2-O1井组的产液剖面资料进行验证。结果表明,所提方法的计算结果与测量结果吻合度较高,精度平均值达75.11%。用该方法计算开发指标,适用性强,能较真实地反映各小层、各方向的产液情况,对现场应用具有指导意义。

Abstract:

On account of the difficulty of Layered Dynamic Analysis of multi-layer sandstone reservoir developed by water flooding, based on the calculation approach of conventional well layer development indexes, combined with dynamic and static splitting methods, and comprehensively considering the parameters such as permeability, porosity, formation coefficient, water saturation, position coefficient, measure coefficient and water injection coefficient, this paper propose a new method which can not only deal with oil and water wells as a unified whole, but also for small layers. The mathematical method for quantitative calculation of development index of directional flow component reflects the essence of seepage mechanics. The proposed method is verified by the liquid production profile data of N2-O1 well group in Daqing Oilfield, and shows high coincidence with the actual production, with average accuracy 75.11%. It has strong applicability to the calculation of development indicators and plays an important guiding role in field application.

Key words: injection-production relationship    development effect    mathematical model    layered water injection    flow component
