Изобретение относитс к бурению нефт ных и газовых скважин.The invention relates to the drilling of oil and gas wells.
Известно устройство дл очистки стенок буровых скважин, состо щее из турбодолота, на вращающем валу которого установлен полый цилиндр с выпускными щел ми, периодически совпадающими со щел ми на неподвижной поверхности неподвижного корпуса турбодолота fl .A device for cleaning the walls of boreholes is known, consisting of a turbodolder, on a rotating shaft of which a hollow cylinder is installed with outlet slots periodically coinciding with the slots on the fixed surface of the fixed turbodolt body fl.
Недостатком указанного устройства вл етс сложность устройства и недостаточные ударные импульсы на стенки скважины.The disadvantage of this device is the complexity of the device and insufficient shock pulses on the walls of the well.
Известно устройство дл разглинизации стенок скважины, содержащее корпус и гидротурбину, размещенную в нижней части корпуса 2}.A device for disintegrating the walls of a well is known, comprising a housing and a hydro turbine located in the lower part of the housing 2}.
Недостаток указанного устройства заключаетс в том, что дл качествен ной разглинизации необходимо создавать высокие давлени в соплах и низкий коэффициент очистки стенок скважины .The disadvantage of this device is that in order to ensure high-quality glistening, it is necessary to create high pressures in the nozzles and a low cleaning coefficient of the borehole walls.
Цель изобретени - повышение эффективности очистки путем удалени ударных импульсов.The purpose of the invention is to increase the cleaning efficiency by removing shock pulses.
Цель достигаетс тем, что устройство дл разглинизации стенок скважин снабжено упруго-колебательными The goal is achieved by the fact that the device for scaling the walls of the wells is provided with elastic-oscillatory
пластинами, концентрично размещенными относительно корпуса и жестко св занными с корпусом в его верхней части,plates concentrically placed relative to the body and rigidly connected to the body in its upper part,
На фиг, 1 изображено предлагаемое устройство, продольный разрез на фиг. 2 - то же, поперечный разрез.FIG. 1 shows the proposed device, a longitudinal section in FIG. 2 - the same cross section.
Устройство состоит из корпуса 1, гидротурбинки 2 с насадками 3 и упруго-колебательных пластин 4.The device consists of a housing 1, hydroturbines 2 with nozzles 3 and elastic-oscillatory plates 4.
Устройство опускают в скважину на бурильных трубах, по которым подаетс промывочна жидкость, гидротурбинка 2 начинает вращатьс , привод в колебательное движение пластины 4, котopыI и возбуждаютс упругие волны.The device is lowered into the well on the drill pipes through which the flushing fluid is supplied, the hydroturbine 2 begins to rotate, driving the plate 4 into oscillatory motion, which are turned on and elastic waves are excited.
Благодар колебательному движению упругих пластин от воздействи на них струи жидкости усиливаютс ударные импульсы и улучшаетс процесс очисткиDue to the oscillatory movement of the elastic plates from the impact of a liquid jet on them, shock pulses are amplified and the cleaning process is improved.
