Description
св заны с дополнительным наружным коаксиально расположенным корпусом 7, снабженным в нижней части отверсти ми 8. Величина радиального зазора между корпусами 6 и 7 определ етс Из услови подачи в скважину количества воздуха, обеспечивающего эффективную работу эрлифта.associated with an additional outer coaxially located body 7, provided with holes 8 in the lower part. The radial clearance between the bodies 6 and 7 is determined from the condition of supply of air into the well, ensuring effective airlift operation.
Центральный шатун 5 св зан с т гой 9, пб всей длине которой жectk6 закреплена винтова спираль 10. На торце т ги 9 жестко смонтирован диск П. Периферийные шатуны 5 через т ги скреплены с диском 12, имеющим осевое отверстие дл свободаого перемещени т ги 9.A central rod 5 is connected with a thrust 9, pb the entire length of which a screw helix 10 is attached. On the end of the thrust rod 9, a disk P is rigidly mounted. .
Устройство работает следующим образом.The device works as follows.
С помощью бурового агрегата его монтируют в скважинё таким образом, чтобы т га 9 установилась напротив фильтровой трубы. Оголовок 2 соедин ют с колонной 1 бурильньУх труб и закрепл ют на устье скважины. Сжатый воздух от компрессоров по колонне 1 бурильных труб, кольцевому зазору между корпусами 6 и 7, а затем через отверсти 8 нагнетают в скважину и произвОД Т откачку воды.v -With the help of the drilling unit, it is mounted in the well in such a way that the ha ha 9 is installed opposite the filter pipe. Cap 2 is connected to drill string 1 and is attached to the wellhead. Compressed air from compressors along string 1 of drill pipe, annular gap between housings 6 and 7, and then, through holes 8, is injected into the well and producing T pumping out of water. V -
При включении в работу вибратора т га 9 с винтовой спиралью 10 и диск 12 совершают When you turn on the vibrator t ha 9 with a helical spiral 10 and the disk 12 make
встречньге колебательньге движени . При этом создаваемые епйралью гидродинамические возмущени наход щейс в скважине жидкости воздействует на стенки скважины по всей высоте рабочей части фильтра.Oscillating motion. At the same time, hydrodynamic perturbations of the fluid in the borehole created by the device affect the borehole walls along the entire height of the working part of the filter.
При работе устройства эффект гидродинамической обработки скважины усиливаетс и за счет того, что между диском 12 и поверхностью спирали возбуждаютс гидродинамические импульсы встречного направлени , закручивающие поток жидкости.During operation of the device, the effect of hydrodynamic treatment of a well is enhanced by the fact that hydrodynamic pulses of opposite direction, which swirl the fluid flow, are excited between the disk 12 and the surface of the helix.
В результате вс поверхность фильтра подвергаетс гидродинамической обработке равномерной интенсивности, что повышает эффективность разглинизации стенок скважины.As a result, the entire surface of the filter is subjected to hydrodynamic processing of uniform intensity, which increases the efficiency of the smoothing of the borehole walls.
