| 摘 要： | 微观驱油实验和数值模拟表明,进入高含水开发阶段,泌阳凹陷下二门油田微观上剩余油主要以斑块状、网络状等形态分布于孔隙中.宏观上,剩余油主要以断层控制型、微构造控制型、压力平衡型、井网未控制型、沉积控制型等5种型式存在.根据剩余油分布,对下二门油田核三段采取了局部井网重组、注水结构调整和高速调整井优化部署等综合调整对策,采...

| Abstract: | Core displacement experiment shows that remaining oil distribution in tiny pore distributed as shapes of speckle and meshwork.On the other hand,it is revealed by numeral simulation that remaining oil distributes as 5 types,such as controlled by fault,by micro - structure,by sedimentary, by well net,and so on.Based on remaining oil distribution, a series of methods to optimize well pattern are applied such as subdivision development series of strata,changing well type,etc,which improves the recovery of H_3 s... |
