Claims (2)

1. Способ проработки ствола скважины перед креплением, включающий удаление глинистой корки со ствола скважины с использованием очистного устройства, спускаемого на колонне бурильных труб, и промывку скважины созданием циркуляции жидкости, отличающийся тем, что в качестве очистного устройства используют бывшее в употреблении трехшарошечное гидромониторное долото, приводимое во вращение роторным способом или забойном двигателем, предварительно заменив две его боковые гидромониторные насадки на насадки с наклонной осью, направленной под острым углом к стенке ствола скважины, при этом длину затопленной струи от выходного отверстия упомянутых насадок до соприкосновения со стенкой ствола скважины выбирают из равенства1. A method of developing a wellbore before mounting, including removing clay cake from the wellbore using a cleaning device that is lowered on the drill pipe string and flushing the well by creating fluid circulation, characterized in that the used three-cone hydraulic monitoring bit is used as a cleaning device, driven into rotation by a rotary method or a downhole motor, after replacing its two lateral hydraulic nozzles with nozzles with an inclined axis directed At an acute angle to the wall of the wellbore, the length of the flooded stream from the outlet of said nozzles to contact with the wall of the wellbore is chosen from the equality L=(5-6) dn,L = (5-6) dn, где L - длина затопленной струи, мм,where L is the length of the flooded stream, mm, dn - диаметр выходного отверстия насадок с наклонной осью, мм.dn is the diameter of the outlet of nozzles with an inclined axis, mm. 2. Способ по п.1, отличающийся тем, что при роторном способе проработку ствола скважины осуществляют со скоростью 20 м/с, а в горизонтальных скважинах не более 10 м/с, при использовании забойного двигателя - 40 м/с.2. The method according to claim 1, characterized in that in the rotary method, the wellbore is drilled at a speed of 20 m / s, and in horizontal wells no more than 10 m / s, when using a downhole motor - 40 m / s.
