摘　　要：A油田水平井普遍采用筛管完井,笼统注水,且水平段存在油污、岩屑、乳化物等物质,井底环境不理想,以流量计为基础的注水剖面测井方法效果不理想.而氧活化测井技术受这些物质的影响较小,通过对油田井下筛管实物的观察,笔者提出基于氧活化测井技术,以盲管段作为点测位置及流量计算点,并给出了采集参数估算方法,实践证明该技术在A油田注水监测应用中能够满足生产需求。The completion method and injection strategy of A oilfield are screen and commingled, moreover, the bottom environment is unideal because of much contamination. It results in the poor application of conventional injection profile logging. the Oxygen activation logging is not affected by these, so through the observation of true screen, it is proposed that the station and flow calculation location is set at blank tubing, and the estimation method of acquisition parameter is also provided. The technology can meet the need of A oilfield dynamic monitor.
