    • A method for transporting gravel to a production zone with a circulating well fluid to uniformly pack the gravel in the annular space in the wall between the perforated liner and the formation whereby the fluid enters the perforated liner after depositing gravel at the top of the annular column of gravel and flows through the liner inner annulus into a tailpipe through which the well fluid is returned to the surface.The well fluid carrier for the gravel is prevented from entering the perforated or slotted liner except at the top of the gravel sheath by a semi-solid material pre-positioned in the slotted liner-tailpipe annulus. The semi-solid material is progressively eroded by the well fluid entering the slotted liner-tailpipe annulus at the top of the gravel sheath.
    • 一种用于将砾石输送到具有循环井流体的生产区域的方法,以将砾石均匀地包装在穿孔衬里和地层之间的壁中的环形空间中,由此在将环形柱的顶部沉积砾石之后流体进入穿孔衬里 的砾石并且流过衬里内环形成一个尾管,井流体通过尾管返回到表面。
