摘要： Sleeves, stabilizers and other well tools may be formed with fluid flow paths or channels extending through one or more blades disposed on the exterior portions of such well tools. The blades and associated fluid flow paths extending therethrough may allow optimum fluid flow rates and volumes to enhance lifting of formation cuttings and downhole debris along with cleaning exterior portions of the well tool and an associated rotary drill bit. Location, configuration, orientation and/or dimensions associated with such blades and associated fluid flow paths or channels may also be modified to provide an enlarged pad or contact surface on exterior portions of one or more blades while maintaining desired fluid flow rates and volumes over exterior portions of the well tool. Such pads or contact surfaces may have optimum surface areas for contacting adjacent portions of a wellbore during directional drilling of the wellbore.

摘要： A downhole tool used in the pressure isolation of adjacent subterranean formations. The downhole tool may comprise flow restriction devices along the outer circumference for impeding flow along the length of the tool. The tool may further comprise a perforating gun and an accumulator. Impeding flow along the length of the tool provides a dynamic flow restriction within the wellbore that precludes fluid flowing from one subterranean zone to an adjacent zone.

摘要： Tubing or piping for carrying a multiphase flow is provided with means for inducing swirl flow, such that the denser components of the flow tend to the outer wall of the tubing or piping, and less dense components tend to the centre of the tubing or piping. The flow thus exhibits a "centrifuge" effect, which prevents lighter or heavier components of the flow from accumulating in upper or lower regions respectively of the tubing or piping, and reduces the risk of airlocks and the like. Preferably, the tubing or piping is in the form of a helix, which may be a low amplitude helix.

摘要： A gravel pack screen assembly has one or more hollow flight augers that a continuous or segmented with multiple upwardly oriented gravel entrances and multiple downwardly oriented gravel exits. The gravel passes through the auger and around any bridge. The auger helps advance the screen into position as well as to centralize it during gravel deposition. The auger protects the screen during run in as well as the internal passages that pass through it due to its structural rigidity. An alternative embodiment features spirally wound tubes with staggered exit locations for better distribution of the gravel.

摘要： A gravel packing method combining fracturing is described. A gun (22) having an exterior auger (24) is used to perforate. With the gun (22) in place, the gravel (14) is positioned around it and the formation is fractured, pushing the gravel into the fractures. The gun (22) is rotated out of the gravel using the auger (24). A screen (30) with an external auger (32) 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 (38) is removed and a flapper (44) closes to minimize fluid loss into the formation. A production string and packer are tagged into the screen (30) and production begins.

摘要： A torque reducing tubing component for insertion in a tubing string to be used in a bore hole. Upsets (22,30,24,26,28) are mounted on the outer surface of the component which reduce the contact between the tubing string and the bore hole wall thereby reducing friction between the tubing string and the bore wall. Grooves (46) on the upsets act to channel fluid around the upsets creating a fluid bearing film between the contact points of the tubing string and the bore wall. A pressure differential is also created around the upsets serving to attract fluid away from the bore wall so improving the efficiency of the circulation of fluid to the surface. Particular reference is made to a torque reducing tubing component for use in a drill string which improves the efficiency of cuttings removal.
