| 摘 要： | 针对低渗透油藏中压裂井压力波传播规律研究匮乏的现状,以压裂井压力波椭圆等压面传播理论为基础,推导了低渗透油藏压裂井平面椭圆径向渗流和椭圆体向心渗流的压力波传播时间与椭圆动边界之间的关系,并与平面平行渗流、平面径向渗流和球面向心渗流的压力波传播规律进行对比。结果表明,椭圆体向心渗流方式下的压力波传播速度最快,其次分别为球面向心流、平面椭圆径向流、平面径向流和平面平行渗流,低渗透油藏各种渗流方式下压力波传播速度都较中高渗透油藏慢。 |
| 关 键 词： | 压裂 特低渗透油藏 渗流 压力波 |

| Abstract: | Based on theory of pressure wave ellipse constant-pressure surface spreading,the relationship between pressure wave propagation time and elliptic mobile boundary is deduced for plane ellipse radial flow and spheroid centripetal flow of fracturing well in low permeability reservoir,and compared with laws of pressure wave spreading of plane parallel flow,plane radial flow and spherical centripetal flow.The results show that pressure wave propagating velocity in the way of spheroid centripetal flow is the fastest,and spherical centripetal flow,plane ellipse radial flow,plane radial flow and plane parallel flow are gradually changed from fast to slow.In general,the pressure wave propagating velocities of the various flow ways in low permeability reservoirs are always slower than those in mid-high permeability reservoirs. |
| Keywords: | fracturing ultra low permeability reservoir fluid flow pressure wave |
