摘要(Abstract)：

为了促进大庆致密油藏的有效开发,探索致密油储层体积改造对可动流体的影响规律,将致密储层的岩样进行了简单劈分、多次劈分、彻底破碎3种不同程度的压裂改造,并对不同状态下的样品进行了核磁共振测试。研究表明:简单压裂对流体的可动用性无明显影响,仅仅改善了流体的流动能力;彻底破碎状态的储层,形成人工油藏后,流体可动用性显著增强,微裂缝更加发育,渗流能力更强;体积改造对渗透率低的储层,效果更明显。
In order to promote the effective development of Daqing tight oil reservoirs and explore the influencing laws of the stimulated reservoir volume(SRV) on the movable fluids,three kinds of different-degree SRV are conducted for the rock samples of the reservoirs,and moreover the NMR tests are caught out for the samples under different conditions.The studies show that the simply fracturing has no obvious effects on the movable fluids,on the contrary the simulation has just improved the flow ability;for the reservoirs with the completely fractured circumstances,after the formation of the artificial oil reservoirs,the developing properties of the movable fluids are greatly strengthened,the micro-fractures are more well-developed,the flow ability becomes much more better;for the lowpermeability reservoir,SRV effects are more obvious.
