脉冲中子氧活化测井技术在油田开发中的应用

大庆油田采用化学驱油技术后，注入介质由单一的水变为聚合物、表面活性剂水溶液以及CDG凝胶等，而注入介质粘度的增大又给注入剖面的测试工作带来很大困难。测井公司研制的脉冲中子氧活化测井仪器在4年的推广应用中得到了拓展和完善，该技术不仅能解决目前注入剖面的测试问题，而且在解决许多工程技术难题中也发挥了作用。

Application of oxygen activation logging technique in oilfield development

With the unceasingly deepened oilfield exploitation, in order to raise recovery ratio, Daqing Oilfield has applied chemical methods. The injected medium has improved from single water to polymer, surfactant solution and CDG gel. The increase of injected medium viscosity leads to difficulties to test the injection profile. Oxygen activation logging instruments developed by Daqing Well Logging Company have been increasingly improved and extended through four years' application and popularization. Oxygen activation logging technique not only can solve injection profile testing problems, but also plays an important role in solving many difficult engineering technique problems. It has been widely applied to oilfield exploitation and has achieved remarkable geological result.
