    摘要: Method and apparatus for gravel packing an open-hole wellbore are disclosed. The apparatus includes a sandscreen disposed in the wellbore thereby creating an annulus between the wellbore and the sandscreen for receiving a gravel slurry. The apparatus further comprises a tubular member or wash pipe which is concentrically disposed in the sandscreen for receiving carrier fluid which passes through the sandscreen and for returning the carrier fluid to the earth's surface. At least one diverter valve is installed in the tubular member for permitting flow of the carrier fluid into the tubular member.
