摘要： Methods of forming chemical casings include drilling a well bore with a drilling fluid having a pH in the range of from about 6 to 10 and comprising water, a water soluble or water dispersible polymer which is capable of being cross-linked by a thermoset resin and causing the resin to be hard and tough when cured, a particulate curable solid thermoset resin, a water soluble or dispersible thermoset resin, and a delayed dispersible acid-catalyst for curing the solid thermoset resin and the water soluble thermoset resin, whereby the drilling fluid forms a filter cake on the walls of the wellbore that cures into a hard and tough cross-linked chemical casing thereon.

摘要： The invention provides a head for injecting a liquid under pressure from a borehole to break up the soil, said head being mounted at the end of a drill string including liquid feed means for feeding a liquid under pressure. The head comprises a body and an outside wall, the body having at least one injection nozzle mounted therein, the nozzle having an inlet diameter equal to d and presenting an axis x,xnull, the body also having duct-forming means. The duct-forming means present a mean line having a first end connected to the bottom end of the liquid feed means and having a second end connected to the nozzle tangentially to the axis x,xnull. The mean line is defined by at least one curved portion presenting a radius of curvature that varies continuously. The right section of the duct-forming means decreases regularly over at least half of its length from its first end to its second end.

摘要： A method and system for accessing subterranean zones from the surface includes a substantially vertical well bore extending from the surface to a target zone, and an articulated well bore extending from the substantially vertical well bore to the target zone. The articulated well bore diverges from the substantially vertical well bore between the surface and the target zone. The system also includes a well bore pattern extending from the articulated well bore in the target zone operable to collect resources from the target zone. The system also includes a subsurface channel operable to communicate resources from the well bore pattern to the substantially vertical well bore. The system further includes a vertical pump disposed in the substantially vertical well bore and operable to lift resources collected in the substantially vertical well bore to the surface.

摘要： Methods of consolidating unconsolidated weak zones or formations and forming chemical casings include drilling a well bore with a drilling fluid having a pH in the range of from about 6 to 10 and that comprises water, a polymeric cationic catalyst which is adsorbed on the mineral surfaces in the weak zone, a particulate curable solid thermoset resin and a delay acid catalyst for curing the solid resin, and forming a filter cake on the walls of the well bore. The filter cake is then contacted with a treating fluid comprising a water soluble or water dispersible polymer which is capable of being crosslinked by a thermoset resin and causing the resin to be hard and tough when cured, and a water soluble or dispersible thermoset resin, whereby the treating fluid components deposit on the filter cake and the thermoset resin cures into a hard and tough cross-linked chemical casing thereon.

摘要： A jet nozzle is provided for drilling holes through the earth, such as drainholes around a well. The nozzle may include orifices for discharging fluid to drive the nozzle forward and includes a disk or other device having orifices to produce a swirling motion to fluid in the body of the nozzle. Swirling fluid is discharged from a front orifice and an extension is placed forward of the front orifice to confine the swirling fluid in a radial direction.

摘要： A method of fracturing a downhole formation according to which a plurality of jet nozzles are located in a spaced relation to the wall of the formation to form an annulus between the nozzles and the formation. A non-acid containing stimulation fluid is pumped at a predetermined pressure through the nozzles, into the annulus, and against the wall of the formation, and a gas is introduced into the annulus so that the stimulation fluid mixes with the gas to generate foam before the mixture is jetted towards the formation to form fractures in the formation. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure; and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims under 37CFR 1.72.

摘要： A drill bit shaft member for tapping a hole in a blast furnace is disclosed. The drill bit shaft member comprises an elongate rod, a first fluid pressure inlet, a second fluid pressure inlet, a chamber in fluid communication with the first fluid pressure inlet and the second fluid pressure inlet, and an outlet in fluid communication with the chamber. A liquid and a gas are combined in the drill bit shaft member to form a mist to provide cooling for the drill bit shaft member. By cooling the drill bit shaft member, certain components that would normally be destroyed may be re-used.

摘要： A method of drilling a well having a first tubular member extending from the surface of the well to a position proximate the bottom of the well. The first tubular member has an inner annulus therethrough. A fluid is pumped into the well through the inner annulus of the first tubular member to flush drilling cuttings out of the well. A fluid is also injected into the well, exterior to the inner annulus, to control the bottom hole circulating pressure in the well.
