示踪剂数值模拟在涠洲12-1油田北块中的应用

涠洲12-1油田北块属于三角洲前缘水下分流河道砂沉积,受河道迁移、改道、侧向加积、多期砂体叠加等沉积作用以及断层、构造的影响,砂体分布与连通性比较复杂,采油井和不同的注水井之间的连通性复杂,如何才能根据静态、动态资料做好连通性分析,这是一个长期困扰着油藏人员的难题。示踪剂技术是第一次在南海西部油田应用,前期研究阶段通过数值模拟,对监测效果进行了预测,为B4,B13示踪剂监测工艺项目的实施提供了依据。

The major type of sub-facies of north block of WZ12-1 oil field is delta front submersed channel sheet sand deposition.For the reason of channel migration 、rerouting、multiple phase sand body superimposition etc.deposition and the function of the fault and structure,the distribution of sand body and connectivity are very complicated ,the connection between production well and different injection wells is also complicated.For a long time,how to analysis the interconnectedness by static and dynamic information puzzled reservoir engineers.The tracer technique firest used in the western oil field of South China Sea.During earlier research period ,forecast the effectiveness of monitoring through numerical simulation,Provide the basis for the project of tracer monitoring technic in well B4,B13.
