摘要: 根据低渗透油藏注水开发的生产特点和水平压裂裂缝的渗流特征,考虑到油藏非均质和各向异性、裂缝导流能力随生产时间的失效性以及不同井网类型等因素的影响,建立了三维油水两相的油藏和水平裂缝渗流数学模型,并构造了模型的高效数值算法。在此基础上研制了水平裂缝参数优化软件,通过计算不同裂缝半径和导流能力对油井产量、含水率、采出程度和最终采收率等指标的影响,优化合理的裂缝参数,用于指导现场的评价和设计工作。

Abstract: A three-dimensional mathematic model of oil-water two phase and crack permeability to horizontal crack oil reservoirs and also its high-efficient algorithm were established,which ac-cording to Product charaeters on low permeability of oil reservoir water injection and seePage of horizontal cracks,and considering unequilibrium Of oil reservoir,anisotropy of permeability rates,craek diversion laPse with time flows and different impacts on
different well Pattems. through caleulating different craeks radius,considering the fracture conduetivity influences on indexes like oil well outPut,moisture content,produce degree,as well as final oil recovery,and oPtimizing rational crack parameters,apter optimum horizontal crack software was develoPed,
which could be used for on-site appraisal and design works.
