摘要
录井解释的目的是识别储集层的产液性质,并对其流体产出能力进行评价。岩石孔隙中多项流体共存时,相对渗透率是衡量其中某一流体通过能力的大小,是岩石、流体间相互作用的动态特征参数。由于相对渗透率分析成本比较高,并且需要岩心样品,不可能每块样品都进行这种分析。利用霍纳普经验公式,借助相对渗透率理论和评价方法,通过实验验证了核磁共振法饱和度与重量法饱和度有较好的相关性,建立了核磁共振录井计算方法,用于计算储集层中的油水相对渗透率,对储集层产液性质进行识别及对产出能力进行评价,同时以实验手段验证了应用这两项资料判断储集层中流体性质及产出能力的可行性。
The purpose of mud logging is to identify reservoir liquidity and evaluate fluid output capacity.When multiphase fluid coexists in pores of rock,the relative permeability is a dynamic parameter of interaction between rock and fluid,which measures the capacity of a fluid passes through the rocks.It is impossible to make a relative permeability analysis of each sample due to its higher analysis cost and the needs of core samples.Using Honarpour empirical equation and the theory and evaluation method of relative permeability,the experiments verified that NMR saturation and weightsaturation method had a good correlation,NMR calculation method was set up,the method was used to calculate oil-water relative permeability of reservoirs,identify the property that reservoirs produce fluid and evaluate the output capacity of the reservoirs.The experiments verified the two dataare workable to determine fluid properties and output capacity.
