摘　　要：低电阻率油气层广泛存在于复杂砂岩油气藏中,但由于低阻油层形成机理研究不足,导致测井解释评价困难,因此需要从低阻成因机理,定量岩石物理实验等方面进行深入研究。油田低阻油层井解释是影响测井解释符合率的主要原因,采用定性定量结合研究思路,利用测井资料对储集层进行定性判别,建立孔隙度、绝对渗透率等测井解释模型,利用侵入校正程序反演原状地层电阻率,充分挖掘低阻油层潜力,提高低阻油气层解释精度。The reservoirs with low resistivity exist widely in complex sandstone reservoirs.However,due to the lack of research on formation mechanism of low resistivity reservoirs,logging interpretation and evaluation are difficult.Therefore,it is necessary to carry out in-depth research on genesis mechanism of low resistivity reservoirs and quantitative rock physics experiments.Wells with low resistance oil layer in oilfield is the main reason affecting the log interpretation confirming rate.So adopting the thoughts of qualitative combined with quantitative research,using logging data to qualitative determination of reservoir,to establish the logging interpretation model of porosity and absolute permeability,etc,using inversion virgin zone resistivity invasion correction procedure,fully improve the low resistance reservoir potential,improve the low resistance oil layer interpretation accuracy.
