本文通过对濮城中渗复杂断块南区沙二上2+3油藏进入后期开发后的剩余油高度分散、井况恶化导致的管外窜漏现象分析,针对油藏开发面临注水开发效果差、采收率提高难度大的难题。提出运用饱和度监测、找漏窜等监测技术,优选了氧活化找漏窜、分层启动压力、声幅变密度、多臂井径测井等相关监测技术,应用了碳氧比、全能谱及脉冲中子饱和度等剩余油监测方法,対油藏存在的问题进行深入的认识和研究,在整体解剖的基础上,优选调整治理对策,进行有效地层间调整挖潜,改善注水开发效果,使水驱采收率得到了提高,水驱效果不断得到改善。
In this paper, we analyzed the phenomenon of high blowout of residual oil after the late stage of Sha 2 Upper 2 + 3 reservoir in the south of Pucheng middle fault complex block and the deterioration of casing condition. In view of the poor effect of water injection development in reservoir development , Oil recovery difficult problem. The monitoring techniques such as saturation monitoring and leak finding are put forward. The monitoring techniques such as oxygen activation seepage leakage, stratified activation pressure, acoustic amplitude densification and multiarm boom logging are optimized. The carbon / oxygen ratio, And pulse neutron saturation monitoring methods such as remaining oil, 対 reservoir problems in-depth understanding and research, based on the overall anatomy, the optimal adjustment of management strategies for effective adjustment of potential to find potential to improve water injection development, Waterflood recovery has been improved, water flooding effect has been improved.
