Investigation of hydrodynamic indexes of ejector gaslift unit
E. E. RamazanovaIn the article investigation of hydrodynamic indexes of gaslift unit providing efficient exploitation of low pressured layers is looked through. While being raised of liquid from the bottom hole, opposed pressure is created to the layer by shoe pressure in the method of gas-lift exploitation. This pressure doesnt allow to use potential possibilities of the layer as much as possible. Calculation of ejector gaslift unit has been carried out to eliminate opposed pressure of shoe pressure to the layer and its hydrodynamic indexes have been determined. In the result of the calculation it has been revealed that soaking ability of the ejector depends on weight expense of submitted gas, size of nozzle area of mixing chamber and correlation of specific weights of mediums. At the time by application of ejector effect of packer technology can be created, it means its working can be possible at small depression of the well.
