WELL-TYPE SELF-CONTROLLED GAS-HYDRODYNAMIC EMITTER- DISPERSER

摘要

FIELD: improved carrying out liquid (water and hydrocarbon condensate) from gas wells and cleaning up nearby stratum area from built-up liquid. SUBSTANCE: dispersing members are placed in series with one member over another inside a case. Among the members are as follows: lower member in the form of converging tube, upper member in the form of diffuser with coaxial central passages in the form of two truncated cones with their apices directed towards each other. Swirl toroidal chamber open to central through passage is placed between the apices. Upper dispersing member is immovable or spring loaded from top of the case. Lower dispersing member is movable and spring loaded about upper dispersing member. At the inlet of lower dispersing member installed is sleeve-separator with central through opening originated in the form of truncated cone broadening towards inlet of lower dispersing member with spiral grooves. Through radial openings equidistant along the length are originated along spiral grooves. Sleeve- separator and case form a chamber open to swirl toroidal chamber. Central through passage of the lower dispersing member has spiral grooves. Lower dispersing member is equipped with a rest that is radially placed near its surface on the side of sleeve-separator. The rest is made in the form of vertical rod with rounded end from bottom. Sleeve-separator is provided with a sleeve in the form of a cylinder truncated from top, that is placed on the side of lower dispersing member. Sleeve cross section looks like inclined plane with upper and lower horizontal surfaces to move the rest along its truncated surface. EFFECT: improved effectiveness of dispersing liquid in gas, and improved acoustic impact on gas/liquid flow in well borehole and nearby bottom area of the stratum at the expense of broadened ultrasonic frequency range regenerated by swirl toroidal chamber and concurrent generation of oscillations of various frequency. 3 dwg
