发明名称 DOWNHOLE DRAW-DOWN PUMP AND METHOD
摘要 An apparatus and method for drawing down a fluid level in a well bore. The apparatus and method includes a first tubular disposed within the well bore forming a well bore annulus therein, an annular nozzle connected to an end of the first tubular, and a second tubular concentrically disposed within the first tubular forming a micro annulus. The annular nozzle includes an annular adapter and a suction tube having an internal section and an external section with an outer diameter less than the outer diameter of the first tubular. The external section of the suction tube may be positioned within a restricted section of the well bore, for example, within a restricted well bore section containing a casing liner to drawn down the fluids and solids within the well bore to produce hydrocarbons.
