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.

摘要： Non conductive supports flank the mounting location of ribs for a wire wrap screen so as to limit penetration into the wire being fed over the ribs and resistance welded notwithstanding variations of applied force from the weld roller. Optionally the wire can be pre-rolled to approximately its end diameter in the finished screen ahead of the time it contacts a rib so as to minimize bending the wire over the rib which thins the wire. The supports are preferably ceramic and provide equal penetration of the rib into the wrap wire despite variations in loading by the weld roller.
摘要翻译： 非导电支撑件位于用于电线包裹屏幕的肋的安装位置，以便限制穿过肋条的电线的穿透，并且即使焊接辊施加的力的变化，电阻也被焊接。 可选地，在接触肋之前，线可以预先滚动到成品丝网的大致其端部直径，以便最小化将线材弯曲到穿过导线的肋上。 尽管焊接辊的负载有所变化，但是支撑件优选地是陶瓷的，并且使肋部能够均匀地贯穿包裹线。
