摘要
以辛47块为代表的多油层断块油藏,在通过多次细分进入特高含水期后,层系内小层间干扰依然严重,开发效果差异大。为充分挖潜剩余油,在深入分析油藏开发历程及现状的基础上,进行小层综合分类,将纵向上不相邻的、但储层物性和开采程度相近的油层重新组合开发层系,并分层系进行注采井网完善。矿场实验表明,层系重组技术可有效改善中低渗储层开发效果,提高多油层断块油藏采收率。
The fault-blocked and muti-layered reservoirs with a high water cut as Xin47,are faced with such troubles that the interference still seriously between the layers of the same bed series,and the difference of development results is greatly.Based on thorough analyses of development course and current situation,Xin47 is studied for the purpose of EOR.Such researches include that the synthetic classification and the recombination of layers with similar physical characteristics and similar current situation,in s...
