摘要
自然电流测井是在调整井中准确划分油层、水淹层行之有效的一种测井方法,这种测井方法在大庆油田研究和推广以来,已经取得了明显的地质效果和显著的经济效益,本文介绍自然电流测井在注水开发油田中,划分水淹薄层的机理和应用效果。
Spontaneous current log is an effective logging method which can beused to accurately distinguish oil-bearing formations and watered-out zonesin adjusting wells. Since it was developed and introduced in Daqing oilfie-ld, remarkable geological effects and economic benefits have been obtained.This paper introduces the mechanism and application effects of the spontane-ous current log used for distinguishing thin watered-out layers in watercontrolled reservoir.
