随着非混相驱、蒸汽驱、SAGD等驱油措施的开展,及时准确地了解注采井间的连通情况,了解注入流体的波及情况,跟踪评价驱油措施的效果,对于下一步方案的实施及措施的调整具有十分重要的作用。本文探讨了井间气体示踪监测技术的研究及应用情况,利用自行研制的气体示踪剂急相关的配套分析解释技术,对冷43-98-560井组注烟道气混相驱进行了动态监测,为下一步方案的实施及措施的调整提供了依据。
With the development of oil-flooding measures such as immiscible flooding, steam flooding and SAGD, the connectivity between injection well and production well is understood in time and accurately, and the situation of injection fluid is understood and the effect of flooding measures is tracked and evaluated. For the implementation of the next step And the adjustment of measures has a very important role. In this paper, the research and application of crosswell gas tracing monitoring technology are discussed. By using the self-developed gas tracer related analysis and interpretation technology, the dynamic mixed gas-phase flooding of the injection well of cold 43-98-560 well group is carried out. Monitoring provides the basis for the implementation of the next program and the adjustment of measures.
