摘　　要：马厂油田经过多年注水开发 ,地下储层油水分布发生变化 ,造成测井过程中电性特征失真 ,对油田生产失去指导参考作用 ,实施的碳氧比监测及DDL -III气举找水结果 ,不能满足油田剩余油监测及堵水工作的要求 ,导致产液结构调整效果差。高精度碳氧比能谱测井进行剩余油监测 ,能有效解决多层合采时主力产水层 ,寻找高含水油层 ,直观反映储集层纵向剩余油分布 ,为油田进行老井挖潜及产液结构调整 ,提供地质依据 ,现场应用效果较好。After a long-time developing with water-injection, the distribution of oil & water in Machang Oilfield reservoir has changed greatly, which results in the falsification of electric feature of logging, and therefore no guide meaning for the oilfield development. Because of the complex geological condition, the result of O/C monitor and DDL-Ⅲ air-lift seeking water can not meet the residual oil monitor and water plugging, which leads to bad effect in production fluid frame adjustment. The application of high precision C/O spectral logging can monitor residual oil, solve the problem of principal water-producing formation in multiplayer commingled production, seek high water-cut oil layer and image the vertical distribution of residual oil so as to provide geological dependency for tapping potential to old oil wells and adjustment to production fluid frame. There is good application effect in Machang Oilfield.
