塔河油田缝洞型油藏单井注氮气影响因素研究

Influential factors analysis of single well nitrogen injection in fracture-vug type reservoirs of Tahe oilfield

  • 摘要: 塔河油田缝洞型油藏随着注水轮次增加,生产效果逐渐变差,2012年开展单井注氮气试验,增油效果显著。运用大量矿场统计数据分析了岩溶地质背景、构造要素、储集体类型、地震反射特征及动态特征对注气效果的影响规律和特征,为塔河油田今后的注气选井和评价工作提供指导。

     

    Abstract: With the increase of the water flooding rounds,the production effect of fracture-vug type reservoirs of Tahe oilfield became poor.Single well nitrogen injection experiment was carried out in2012 and the oil production increased obviously.Through a large number of field statistics,the analysis of karst geological setting,tectonic elements,reservoir types,seismic reflection characteristics and dynamic characteristics of gas injection effect and the characteristics of Tahe oilfield has been done,which provided guidance for gas injection wells and evaluation in the future.
