| 摘 要： | 吉林油田同位素吸水剖面测井采用~(113)In同位素追踪技术,根据同位素追踪过程解释基本可以判断配水层段吸水情况。但是在注水井存在沾污、大孔道以及串槽等影响时,吸水面积确定比较困难。在同位素测井中增加井温、流量参数,通过多参数综合解释,不仅可以对沾污影响进行合理校正,确定准确的小层吸水量,而且能够正确判断各级封隔器、配水器的工作情况,在地层存在大孔道的情况下,确定地层的吸水面积。吸水剖面综合解释方法在吉林油田已普遍应用,见到明显的效果。

| Abstract: | The technology of ~(113)In tracing is used in profile-log of water injection widely in Jilin Oilfield.By tracing the movement of ~(113)In,we can know distribution of water in the injection wells.But the technology is limited by the isotope contamination,large pore paths and channeling,it is difficult to determine injected-water volume accurately.Now at the same time of logging we add two parameters- temperature and flowmeter,by the way of multi-parameter explaining,it is possible to know the situation of packers,and determine injected-water volume of formation in the wells,especially existing channeling of oil zones in the same well.The method of comprehensive interpretation of injection profile log data is effective in oilfield production. |
