摘要
随着长庆油田注水开采程度的不断提高,水淹层评价成为一项重要工作。俄罗斯过套管电阻率测井仪(ECOS)采用2个供电电极,能在金属套管井中测量地层电阻率,具有较大的横向探测深度,在水淹层评价方面表现出了独特的应用优势。基于大量的过套管电阻率测井资料,采用油藏衰竭指数法对长庆油田L41井进行了详细的储层水淹层评价工作,评价结论与完井测井解释结论基本一致,表明该方法在长庆油田具有可行性和有效性。
With the continuous improvement of waterflooded development in Changqing Oilfield,the waterflooding evaluation became one of the important tasks.Two electrodes were used for power supply in Russian through-casing resistivity(ECOS)logging tool,by which formation resistivity in the metal casing could be measured,it had a larger horizontal depth,it had a particular advantage in evaluating the waterflooded reservoirs.Based on large number of logging data,the method of reservoir depletion index was used for waterflooded reservoir evaluation for Well L41 in Changqing Oilfield.The evaluation result is basically consistent with that of logging interpretation,it indicates that the method is feasible and effective.
