摘要： Device for producing bored piles having an auger, which along at least part of the auger length is surrounded by a rotating encasing tube and during boring the encasing tube is rotated in or counter to the rotation direction of the auger and in which the auger and the encasing tube are introduced essentially simultaneously into the ground during boring. To facilitate material discharge, the surface roughness of the auger helix surface pointing in the feed direction is increased compared with the roughness of the rolled surfaces in a complete or partial surface manner by additional machining. The increase in the surface roughness extends at least over the auger length necessary for feed purposes.

摘要： A drill bit includes a one-piece cylindrical drill bit tube having a longitudinal axis and defining cylindrical surfaces including an inner cylindrical surface and an outer cylindrical surface. At least one of the cylindrical surfaces is configured to include deformations comprising at least one of embossments and recesses, all of the deformations appear over an entire length of the tube. At least some of the deformations are finite over the at least one of the cylindrical surfaces, the deformations further being adapted to stiffen the tube in the longitudinal direction without additional material reinforcements being disposed on the tube. The drill bit further includes hard-metal cutting elements disposed on a front face of the tube.

摘要： A decentralizer for a diverter, a centralizing guide bushing and a downhole-deployable locating and orienting subsystem. The subsystem is capable of three modes of operation: (a) a running mode in which an actuating mandrel is in a first axial limit position with respect to a common mandrel, the actuating mandrel placing first and second double-acting springs in a stowed position wherein locating and orienting keys are retracted radially inwardly with respect to the common mandrel to shield the locating and orienting keys from substantial contact with a surrounding well flow conductor as the common mandrel traverses therethrough, (b) a locating mode in which the actuating mandrel is in an intermediate axial position with respect to the common mandrel, the actuating mandrel placing the first and second double-acting springs in a deployed position resiliently to bias the locating and orienting keys radially outwardly with respect to the common mandrel to seek a locating and orienting profile on an inner surface of a surrounding honed bore within the surrounding well flow conductor, and (c) a set mode in which the actuating mandrel is in a second axial limit position with respect to the common mandrel, the actuating mandrel directly engaging and stiffly retaining the locating and orienting keys in engagement with the locating and orienting profile thereby to fix the common mandrel in a desired location and orientation with respect to the honed bore.

摘要： The invention comprises a tool with at least one extending member which causes the fluids moving in the wellbore after perforation to increase in velocity. The velocity is further increased by an auxiliary flowpath which permits the addition of fluid from the surface or from elsewhere in the wellbore or formation to be pumped to mix with the other fluids being produced after perforation. The auxiliary fluid further increases velocity, thus improving the ability of the mixture of formation and auxiliary fluid to entrain debris and remove it from the wellbore.

摘要： The invention features a perforating gun, with an external auger, which can be mounted to a tubing string. The auger facilitates removal of the gun after the sand is placed in the perforations. The perforating gun with external auger promotes the clean-up of the debris from the perforations after the gun is shot and facilitates the movement of the gun out of the sand. The sand can be spotted near the perforations without exposure to the formation of any kill fluids. The perforating gun with external auger need not be moved prior to admission of sand into the perforations. The assembly can be used so that preferred fluids, such as stimulating fluids, can be used to circulate the sand until the sand has been spotted adjacent the formation, whereupon the stimulating fluid is squeezed into the formation, leaving the sand in the perforations. The amount of fluid displaced into the formation is minimized and the selection of fluid helps to stimulate the subsequent flow during production.
