摘要(Abstract)：

中国大部分油藏是注淡水开发,示踪剂监测确定井间地层参数的方法比较简单且技术成熟,但注海水开发的油田,由于海水中离子的多样性和复杂性,对通过示踪剂检测确定井间连通性的方法提出了挑战。为了探索注海水条件下的示踪剂检测方法,以中东地区H油藏为研究平台,以化学分析和仪器检测为技术手段,进行了大量的室内实验。结果表明:由于海水中Br-的存在,对于示踪剂中Br-的检测提出了严格的时间和用量要求,需要加入适量氧化剂,去除海水中含有的Br-之后,再检测示踪剂中的Br-;在海水中,硫氰酸铵、亚硝酸钠和溴化钠3种示踪剂彼此兼容,示踪剂检测可行。研究成果对该油藏后期大面积注海水开发具有指导作用。
Most of the domestic oil reservoirs are developed by the fresh water in China. Although the method is relatively simple to determine the formation parameters between the wells with the tracer monitoring,it is more mature. But for the oilfields developed by the sea water injection,because of the diversity and complexity of the ions in sea water,the method is challenged to determine the connectivity between the wells. In order to explore the tracer detection methods under the condition of injecting the sea water,a large number of the indoor experiments are carried out by taking Oil Reservoir H in Middle East as the researching platform and moreover regarding the chemical analyses and instrumental detections as the technical means. The study achievements show that due to the presence of Br-in the seat water,when detecting Br-in the tracer,the strict time and quantity were presented,a proper amount of the oxidation agent should be added to remove the Br-containing in the seawater,and then test the Br-in the tracer; the tracer test was feasible by the compatible three tracers: ammonium thiocyanate,sodium nitrite and sodium bromide in the seawater. The research results possess the guiding significance for the developmentof large area water injection in the oil reservoir.
