摘要
本文在文献3的基础上,提出了一种计算视电阻率梯度异常的旁井参照法。该方法是三极梯度法的重要组成部分,它不仅弥补了本井参照法不能对油气藏作垂向预测的缺陷,而且只有采用旁并参照法才有可能计算时间校正系数,消除因地下介质电阻率随时间的变化对三极梯度法观测值的干扰,进而对油气藏进行开发监测。
Sied-hole reference for estimating the gradient anomaly of apparent resistivity is put forward on the basis of literature 3. It is the major part of trielectrode gradient measurernent technique. The sideinhole reference remedies the defect that self-hole reference fails to vertically predict hydrocarbon reservoir. What is more, only by side-hole reference,can we obtain time correction coefficient and eliminate the influ-ence on trielectrode-gradient observation values that is caused because subsurface resistivity varies with time,thus successfuIly monitoring reservoir development.
