摘　　要：综合分析低电阻率油气层5方面的地质特征与储集层电阻率变化的机理,以及低电阻率油气层的沉积特征,指出常规电法测井识别低电阻率油气层的局限性,提出应用薄层测井、核磁共振测井与地球化学分析方法来识别低阻油气层,并在实际应用中取得了较好的效果。Based on comprehensive analysis of geological features of low resistivity oil and gas reservoirs in five aspects and the mechanism leading to resistivity changes, together with the depositional characteristics, it is pointed out that conventional resistivity logging techniques have their limitations in identifying low resistivity oil and gas reservoirs. A new method is proposed that uses thin - bed logging, NMR logging and geoehemical analysis to identify low resistivity oil and gas reservoirs. Good geological results have been achieved in practical applications .
