Title: Method for determining pressure profiles in wellbores, flowlines and pipelines, and use of such method
Inventor: GUDMUNDSSON JON STEINAR
IPC: E21B47/06
Filed: 2000-09-22
Granted: 2008-11-04
Abstract: Method for determining pressure profiles in wellbores, flowlines and pipelines flowing singlephase and multiphase fluids and use of such a method. The flow is temporarily stopped or restricted with a quick acting valve and the pressure is continuously recorded at a point a short distance upstream, using the Joukowsky equation: .DELTA.p_a=.rho. u a, where .rho.(kg/m3) represents the fluid density, u(m/s) the fluid flowing velocity and a (m/s) the speed of sound in the fluid, to estimate the magnitude of the water hammer and using the Darcy-Weisbach equation: .DELTA._f=(f/2)(.DELTA.L/d)).rho.u~2, where f (dimensionless) is the friction factor, L (m) the pipe length, d (m) pipe diameter, (kg/m3), .rho. (kg/m3) fluid density and u (m/s) fluid velocity, to determine the frictional pressure drop, thereby obtaining a time-log of the pressure change in the wellbore, flowline or pipeline measured. A distance-log of pressure change may be obtained from the time-log and an estimate of the speed of sound in the actual multiphase flow media, using the formula:  .DELTA.L = 0.5 a .DELTA.t, to obtain the relation between time (.DELTA.t) and distance (.DELTA.L). The method is useful for detecting and locating leakages, inflow, deposits, collapses etc.

Abstract: A wrapping apparatus for wrapping a continuous elongated article, such as a continuous stack of interfolded paper towels, includes a web supply section that supplies a pair of continuous webs of wrapping material, and a wrapping section for applying the continuous pair of webs about the article. The web supply section includes a pair of web supply stations for each web of wrapping material, and a source of wrapping material, such as a supply roll, is located at each web supply station. The web supply section includes a splicing mechanism for each pair of web supply stations, for splicing together the trailing end of a web from an exhausted supply roll of wrapping material with the leading end of a web from a fresh supply roll of wrapping material, to provide a continuous web of wrapping material to the wrapping section. The web supply section includes a festoon- type web storage mechanism in which the web downstream of the splicing mechanism is trained about a series of rollers in a serpentine path. The rollers are movable toward and away from each other, e.g. by mounting one set of rollers to a movable frame, to enable the web to be continuously supplied to the wrapping section during the splicing operation, which maintains the web ends stationary during splicing. The webs of wrapping material are applied to the elongated article such that side areas of the webs overlap each other, and adhesive such as hot glue is applied between the overlapping areas of the webs. A pressure application assembly applies pressure to the overlapping areas of the webs to even out the adhesive, and the wrapped elongated article is discharged from the wrapping section through a discharge passage which includes a cooling assembly for extracting heat from the seal between the overlapping webs. The wrapped elongated article is then discharged from the wrapping section for subsequent processing.

Abstract: A method for manufacturing a highly-crystallized oxide powder, wherein an oxide powder is produced by ejecting a starting material powder comprising at least one metal element and/or semimetal element, which will become a constituent component of the oxide, into a reaction vessel together with a carrier gas through a nozzle; and heating the starting material powder at a temperature higher than the decomposition temperature or reaction temperature thereof and not lower than (Tm/2)°C, where Tm°C stands for a melting point of the oxide, in a state in which the starting material powder is dispersed in a gas phase at a concentration of not higher than 10 g/L. In the above method, the starting material powder may be mixed and dispersed in the carrier gas by using a dispersing machine prior to being ejected into the reaction vessel through a nozzle. The resultant oxide powder has a high crystallinity, a high dispersibility, and a uniform particle size, without introducing impurities thereinto, by a low-cost and simple production equipment.

Abstract: Le dispositif décrit comprend une chambre de formation de gouttes conçue pour être raccordée avec une conduite d'eau ordinaire, une plaque métallique et une buse qui est connecté avec la chambre de formation de gouttes et placée au dessus de la plaque métallique, et un réceptacle de récupération. La chambre de formation de gouttes a pour fonction de convertir le flux d'eau continu provenant de la conduite en gouttes discrètes, entraînant ainsi la formation d'une réserve d'eau au fond de la chambre. Cette réserve est électriquement isolée de l'alimentation en eau, mais reçoit de l'eau de manière continue. L'eau contenue dans le réservoir est envoyée dans la buse et pulvérisée sur la plaque d'acier. Une tension électrique est appliquée sur la buse et par conséquent sur l'eau, et attire les impuretés contenues dans l'air. Ces dernières se lient avec l'eau et sont entraînées par celle ci dans le réceptacle de collecte, lequel est ensuite vidé dans le système d'évacuation d'eau de la maison.
