子长油田中庄区长6段储层特征及注水影响评价

Reservoir Characteristics and Impact Assessment of Waterflooding of Chang 6 Reservoir in Zhongzhuang Area,Zichang Oilfield

整个陕北斜坡地区的储层,其物性条件都不是很好,属于低渗透储层。在这种情况下,提高油气的开发就需要借助外部动力。通过对储层岩性、孔隙结构、物性、储层敏感性及地层流体性质的研究,利用权重估值法对研究地区注水开发效果进行半定量计算,为油田注水开发可行性提供参考。

The reservoir in the north Shaanxi slope area has poor properties condition,belongs to low permeability reservoirs.In such cases,to improve oil and gas development will need to rely on external power.Through analysis of reservoir lithology,pore structure,physical properties,reservoir sensitivity and characteristics of formation fluid,semiquantitative calculation for effect of waterflooding development was carried out by weight valuation method,which can provide a reference for the feasibility of waterflooding development.
