影响注水开发效果的因素分为两个方面,一是井网井距的合理调整(外部因素),二是注水油藏本身的特征适应情况(内在因素).本文通过对研究区域储层岩性、孔隙结构、物性、储层敏感性及地层流体性质的研究,利用权重估值法对油藏自身条件的注水效果进行半定量计算,为油田注水开发可行性提供参考并予以推广.%Water flooding development is influenced by adjustment to well pattern and spacing (external factors)as well as the characteristics of reservoir (internal factors). The semi-quantitative calculation on effect of water flooding are carried out by weight valuation method in terms of the researches on lithology,pore structure,physical properties,lithology and sensitivity of reservoir and features of formation fluids. It proves to be useful for improving feasibility of the technology in oilfields.
