摘要
准确判断注采井之间的连通性，在改善注入流体驱替效率和指导调剖堵水作业等方面具有重要意义。对于注采井系统，注入井的注入信息反馈为采油井的产出信息，这一过程可以近似为脉冲响应过程，从而可以建立注采井脉冲响应模型对注采井系统进行描述。以生产动态资料为基础，利用集合卡尔曼滤波方法对脉冲响应模型响应关系进行计算，可以得到注采井之间随时间动态变化的响应关系，即注采井连通度，从而实现注采井连通性动态跟踪评价。示踪剂对比分析结果表明，该评价方法体系具有一定的实用性和可靠性，可以有效地进行注采井连通性动态跟踪评价。
The exact judgement of the injectorproducer connectivity possesses the important significance in impro ving the sweeping efficiency of the injected fluids and guiding profile control, water plugging and other operations. For the injectorproducer system the the feedback information from the injection wells can response the production information of the producers, this process can be approximated as the impulse response process, thus the injector producer pulse response model can be established to characterize the injectorproducer system. Based on the pro duction performance data, with the help of integrated Kalman filtering method, the response relation can be calcu lated for the model, thus the relation of the dynamic changes among the injectors and producers with the time can be obtained i. e. the connectivity of injectors and producers. Finally the dynamic tracking evaluation for the above connectivity can be realized. The analysis and contrast results of the tracer show that the evaluating system has a certain practicality and reliability, and moreover can be effectively used to trace and evaluate the dynamic connectivity among the injectors and producers.
