【摘要】：海上油田示踪剂测试成本高、测试资料少,应用示踪剂产出曲线评价井间动态连通性较为困难。根据现场监测获得的产出聚合物数据,结合数值模拟技术进行产出聚合物敏感性分析,并在此基础上对单井聚合物产出曲线拟合,利用CMG数值模拟软件的多组分定义功能实现了聚合物产出方向的识别及产出量的劈分。应用该方法评价了L油田A10注聚井组的井间动态连通性,并根据井间连通情况,提出了相应调整对策。应用结果表明:注水井A10与生产井A44井间见聚速度快、产出聚合物多,存在优势渗流通道,再结合生产井A44产液剖面测试结果,建议对A10井调剖、A44井卡水,预计措施实施后A44井产量翻番,增油降水效果明显。
[Abstract]:The testing cost of tracer in offshore oilfield is high and the test data are few. It is difficult to evaluate the dynamic connectivity between wells by using tracer output curve. Combined with numerical simulation technology, the sensitivity analysis of polymer production is carried out, and on the basis of this, the polymer output curve of single well is fitted. The multi-component definition function of CMG numerical simulation software is used to identify the direction of polymer production and split the output. The dynamic connectivity between wells of A10 polymer injection well group in L oilfield is evaluated by using this method. According to the condition of inter-well connectivity, the corresponding adjustment countermeasures are put forward. The application results show that the convergence rate between water injection well A10 and production well A44 is fast, the polymer production is more, and there is an advantage seepage channel. Combined with the test results of production well A44 production profile, it is suggested that the oil production of well A44 should be doubled and the effect of increasing oil and precipitation should be obvious after the implementation of the measures for profile control and profile control of well A44.
