Title: Method of operation of a well jet device in well testing and development and the well jet device for carrying out said method
Inventor: KHOMYNETS ZINOVIY DMITRIEVICH
IPC: F04F5/10
Filed: 2002-04-24
Abstract: The invention relates to jet device used for extracting oil from wells. The inventive method consists in the following: a pump, a connecting and disconnecting unit, a valve unit, a packer and a shank are mounted on a tubing string before actuating the inventive device. A perforator is run into the well on a mounting seat in the pass channel of the pump, the packer being released. Differential pressure being produced, the perforator is blasted against the productive stratum which is then drained. The perforator being replaced by the transmitter and receiver-transducer of physical fields, the stratum is studied while the pump operates. Said transmitter and receiver-transducer being pulled from the well, a valve chamber and a blocking insert separating the cavity of the tubing string from environment are thrown into the well. The well starts to work in a natural flow regime. When the production rate decreases, the well is suspended, the blocking insert is substituted by a depression insert provided with a manometer and a debitometer and the well production is measured while fluids are pumped out. The flow rate-bottomhole pressure graph is plotted according to indications of instruments and interpreted, thereby defining the sizes of a pump. The required pump is run into the well along the tubing string and the well is put into operation by a power method. The invention is directed to improve reliability of the operation of said device.

Inventor: LINDNER MARIE
IPC: B02C17/02
Filed: 2002-06-24
Abstract: L'invention concerne un procédé de criblage à haut rendement consistant à réduire la taille de particules d'un composé candidat, peu soluble, de sorte qu'il présente une taille de particules d'environ 1 micron au maximum, au moyen d'un broyeur de petite taille ou de procédés microfluidiques. Le produit obtenu selon ce procédé est une dispersion du composé candidat nanoparticulaire présentant au moins un stabilisant adsorbé sur sa surface. La réduction de la taille des particules entraîne une augmentation de la solubilité et/ou de la dispersibilité du composant, et par conséquent une amélioration du rendement du criblage à haut rendement effectué en association avec le procédé de réduction de la taille des particules. Ce dernier peut être effectué avant le criblage à haut rendement pour rendre les composés criblés solubles et/ou dispersibles, ou après le criblage à haut rendement pour valider un composé insoluble ou peu soluble déterminé comme étant actif après le criblage.
