采用自行设计的人工振动模拟系统,研究了人工振动对岩石渗透率、不同阶段水驱采收率的影响,针对辽河油田试验区块进行了人工振动作用参数的优化。研究表明,人工振动作用可提高岩石的渗透率,提高水驱采收率,降低含水率,且人工振动增产效果与振动参数有关;试验得到的优化参数与现场实际优化参数较吻合。

Artificial Vibration Oil Production(AVOP) is a new and prospective method for enhanced oil recovery.A new system for artificial vibrating simulation was designed and effect of artificial vibration on core permeability,oil recovery under different stage of water flooding was studied.Experiments show that action of artificial vibration can improve the permeability of cores and oil recovery,while decrease the water cut at the stage of high water-cut.The results of oil recovery increment were related to the vibrating parameters.The optimum parameters got in the experiments is almost identical to the parameters used in the field tests.
