摘要
氧活化找漏找窜测试技术是利用脉冲中子与氧元素相互作用后放射出特征伽马射线,通过检测伽马射线来确定仪器周围含氧流体的流动情况,根据被氧活化的水到达探测器的时间计算出该截面的水流,从而确定水流来源。详细介绍了桥口油田油水井的主要窜漏类型,并研究了油水井不同窜漏类型在注入条件下的找漏窜工艺技术。该测井技术经过改进后分别在桥口油田19口井上进行找漏找窜的应用,测试符合率达88.2%。测试后采取相应措施有效率86.7%,测试成功率和窜漏识别精度得到提高,取得了很好的增产效果。
Finding the leakage and channeling with oxygen activation logging technology is to use the gamma ray, which is radiated after the interaction of pulsed nertron and oxygen element, to define the flowing of oxygenic fluid around instrument through the detection of gamma ray. The sectional waterflow can be calculated in terms of the arrival time of oxygen activation waterflow to a detecter, which can deternine the waterflow source. This paper describes the main leakage and channeling types of oil and water wells in Qiaokou Oilfield and researches the finding leakage and channeling technology under the injection condition according to the different leakage and channeling types of oil and water wells. The improved logging technology was used in 19 wells of Qiaokou Oilfield for finding leakage and channeling. The testing coincidence rate reaches 88.2% and the effective rate of corresponding measures after testing is 86.7%. The testing success rate and accuracy of finding leakage and channling is improved. A good stimulation effect has been obtained.
