摘要: 运用稳态逐次替换法,研究了低渗透油藏不同渗流方式下弹性液体不稳定渗流压力波的传播规律,发现在平面平行渗流、平面径向渗流和球面向心渗流3种渗流方式中,球面向心渗流方式下的压力波传播速度为最快,平面平行渗流压力波传播速度为最慢;低渗透油藏比中高渗透油藏的压力波传播速度慢。

Abstract: The propagation of pressure wave of unsteady flow of elastic fluid in low permeability reservoirs is researched using the steady state replacement method. Among the different percolation processes such as planoparallel flow, planoradial flow and spherical centripetal flow, the pressure wave propagating velocity is the fastest under the spherical centripetal flow, and the slowest under the planoparallel flow. And low permeability reservoir is slower than mid-high permeability reservoir in pressure wave propagating velocity.

Key words: low permeability, pressure, travel time, percolation
