摘要： A method and apparatus for producing (e.g. heavy oil) through a wellbore which passes through a permafrost layer. To maintain an acceptable flow temperature inside the production tubing, a heating element (e.g. electrical power cable having its leads short-circuited) is lowered down the production tubing to generate heat inside the tubing when electricity is supplied thereto. A sensor is provided to sense the temperature inside the tubing and activate a source to supply electricity to the cable whenever the temperature inside the production tubing drops below the desired temperature.

摘要： A method and apparatus for desanding oil produced from a subterranean oil-bearing formation through a wellbore, the method comprising: flowing oil from the oil-bearing formation upwardly through a first tubing at a velocity sufficient to carry sand entrained in the oil upwardly through the first tubing; flowing the oil from the first tubing upwardly through a larger tubular section at a velocity sufficient to carry sand entrained in the oil upwardly to a perforated section positioned in a second tubing in the larger tubular section, the perforated section being positioned near the upper end of the larger tubular section; passing the oil through the perforated section and through a circumferential path around a dip tube positioned beneath the perforated section to centrifugally separate sand from the oil so that the sand is passed outwardly toward an inner diameter of the second tubing and downwardly to storage in a lower portion of the second tubing; and flowing the oil upwardly through the dip tube to a pump and through the pump and a third tubing to oil recovery at the surface.

摘要： A method and a pumping system for lifting formation fluids from a production zone in a wellbore which allows the pump unit to be retrieved through the production tubing while leaving the tubing, electrical cable, and the remainder of the components of the pumping system in place. A pump unit is retrievably positioned within the production tubing and is releasably connected to a downhole motor whereby the motor will drive the pump when electricity is supplied thereto through the cable secured to the tubing. This allows the pump unit to be both retrieved and installed through the tubing without removing the production tubing string, the motor, or the electrical cable from the wellbore.

摘要： A downhole pump system which allows the pump unit to be retrieved and re-installed through the production tubing while leaving the tubing, electrical cable, and the remainder of the components of the pump system in place. Preferably, the pump unit is run on a string of coiled-tubing through a lubricator which is positioned downhole in the production tubing. The pump unit includes a slip-joint at its upper end which (a) allows the length of the pump unit to be adjusted to compensate for the spacing between the seating surface and latching grooves in the nipple and (b) allows the pressures to be balanced across the pump unit during installation and retrieval.

摘要： A method and apparatus for removing solids from a substantially horizontal section of a wellbore which allows the use of coiled tubing as a workstring without requiring the removal of the production tubing from the wellbore. Guide tubing, which is left in the wellbore, extends from the surface through the horizontal section and is adapted to guide a string of slightly smaller-diameter, coiled tubing through the horizontal section. Wash fluid, e.g. water, flows through a nozzle on the coiled tubing and out through openings in the guide tubing directly into the solids to form a slurry therewith. The slurry is then pumped out of the wellbore through the production tubing and/or reenters the guide tubing through other opening(s) therein to flow to the surface through the annulus which exists between the coiled tubing and the guide tubing.

摘要： This invention relates to a downhole hydraulic pump for hydrocarbon wells that is installed and operated using coiled tubing. The downhole hydraulic pump is driven by a hydraulic power system positioned at the surface and connected through a closed loop system using multiple channels of the coiled tubing. The coiled tubing is formed of a combination of channels including strength component such as steel and having one channel that is at least lined with a non-metallic corrosion resistant surface where clean hydraulic fluid is carried from the hydraulic power system to the downhole hydraulic pump through the non-metallic corrosion resistant channel so to be less likely to pick up manufacturing and environmental particulates and corrosion by-products within the channel carrying the hydraulic fluid to the downhole hydraulic pump. The non-metallic corrosion resistant lined channel may comprise plastic pipe.

摘要： A gas-liquid separator or slug catcher includes an inlet flow diverter for disposition in a separator vessel wherein the flow diverter includes a generally cylindrical inner wall member and a cylindrical cap having a depending wall spaced from and surrounding the inner wall member. The cap includes a transverse top wall which is spaced from the top edge of the inner wall to provide an overflow path for surges of liquid and/or gas. An inlet conduit extends to a tangential opening formed in the inner wall member for introducing fluid into an interior chamber. The inner wall member includes a transverse bottomplate which is provided with a series of openings around its periphery. Slugs of gas and two-phase liquid flow in a vortical manner in the diverter chamber whereby the gas is separated from the liquid mixture and some de-emulsification of liquid is accomplished through centrifugal forces. Deswirled liquid exits the apparatus through a bottomplate under the gas-liquid interface in the separator vessel. In an alternate embodiment of the apparatus, a series of circumferentially and longitudinally spaced perforations are formed in the inner wall member and the depending wall of the cap member.

摘要： This invention relates to a coiled tubing installed and operated hydraulically driven downhole pump for hydrocarbon wells and especially hydrocarbon gas wells that are prone to produce fluids that choke gas production. The hydraulically driven downhole pump is driven by a closed loop surface positioned hydraulic power system. Should the hydraulically driven downhole pump become inoperative, it may be quickly retrieved and immediately replaced using a coiled tubing unit as compared to a workover rig. A coiled tubing unit is able to pull the coiled tubing string and re-install the string quite rapidly because the coiled tubing does not have joints that need to be disassembled or reconnected. The manpower needs and costs for replacement are considerably less and lost production of the well is substantially reduced.

摘要： A liquid jet manifold arrangement for process separator vessels for removing solids such as sand and sediment which accumulate along the bottom wall of the vessel during operation. A plurality of elongated manifolds are arranged to extend longitudinally along the vessel bottom wall and each manifold is provided with an array of jet nozzles which are arranged along the manifold bottom side and top side, respectively. The nozzles extend in a direction such as to create a substantially vortical flow of liquid to entrain and urge the fluidized solids mixture toward the solid removal outlet opening in the vessel. The manifolds are supported in a standoff position from the vessel bottom wall by adjustable support brackets and a generally arcuate shield is supported above and spaced from each of the jet manifolds to redirect the liquid flow out of the nozzles to enhance the vortical flow pattern.
