    摘要: A gravel packing method combining fracturing is described. A gun having an exterior auger is used to perforate. With the gun in place, the gravel is positioned around it and the formation is fractured, pushing the gravel into the fractures. The gun is rotated out of the gravel using the auger. A screen with an external auger is run in and rotated into the packed gravel in the wellbore while being vibrated at the same time. After the screen is advanced into position the vibrator is removed and a flapper closes to minimize fluid loss into the formation. A production string and packer are tagged into the screen and production begins.
