发明名称 Method and apparatus for cleaning wellbore perforations
摘要 An apparatus and method are disclosed for removing debris from a recently perforated formation. A vacuum source, such as a subsurface jet pump is employed, coupled with a sealing arrangement to isolate a portion of the recently perforated formation. The vacuum device increases the velocity of the formation fluids to enable them to entrain the debris and bring it to the surface.
