| 摘 要： | 由于裂缝性油藏储集空间物理性质的复杂性和特殊性,渗吸效果控制着低渗透裂缝性油藏水驱开发动态与开发效果,而脉冲渗吸驱油一直被认为是低渗透裂缝性油藏有效的开发方式。在室内实验研究的基础上,结合油藏工程等理论知识对脉冲渗吸驱油机理进行了研究,得出脉冲增压改善基质岩块孔隙中渗吸条件是脉冲注水方式提高渗吸驱油效率的根本原因。 |

| Abstract: | Physical nature of reservoir space of fracture reservoir is complex and specified,imbibition effects controls water flooding effects,and the pulse imbibition displacement has always been considered as an effective development mode of low-permeability fractured reservoirs.On the basis of indoor experiment,theoretical knowledge of reservoir engineering has been used to study the pulse imbibition displacement mechanism and results show that changing the condition of imbibition by pulse pressurization is the ul... |
