Claims (5)

1. Способ бурения скважин, при котором осуществляется последовательное присоединение бурильных труб к бурильной колонне по мере ухода бура на глубину и последовательное отсоединение бурильных труб от бурильной колонны при выводе бура на поверхность после бурения, отличающийся тем, что соединение бурильных труб делают неразъемным лазерной сваркой за один проход, а отсоединение ведут лазерной резкой за один проход.1. A method of drilling wells, in which the drill pipes are sequentially connected to the drill string as the drill goes deeper and the drill pipes are sequentially disconnected from the drill string when the drill is brought to the surface after drilling, characterized in that the drill pipe connection is made one-piece laser welding for one pass, and disconnection is carried out by laser cutting in one pass. 2. Способ бурения скважин по п. 1, отличающийся тем, что лазерная резка и лазерная сварка ведутся неподвижным лазером и вращающимися вокруг своей оси бурильными трубами. 2. The method of drilling wells according to claim 1, characterized in that the laser cutting and laser welding are carried out by a stationary laser and drill pipes rotating around its axis. 3. Способ бурения скважин по п. 1, отличающийся тем, что лазерная резка и лазерная сварка ведутся обходящим по периметру стыка (сварного шва) лазерным лучом, при неподвижных трубах. 3. The method of drilling wells according to claim 1, characterized in that the laser cutting and laser welding are carried out by a laser beam bypassing the perimeter of the joint (weld), with the tubes stationary. 4. Способ бурения скважин по каждому из пп. 1 - 3, отличающийся тем, что места лазерной сварки и лазерной резки совпадают. 4. The method of drilling wells for each of paragraphs. 1 to 3, characterized in that the places of laser welding and laser cutting are the same. 5. Способ бурения скважин по пп. 1 и 2, отличающийся тем, что лазерную сварку бурильных труб ведут одновременно с бурением, причем бурильные трубы осуществляют винтовое вращение вокруг собственной оси, а лазерный луч опускается на расстояние равное глубине бурения за один оборот бурильной колонны. 5. The method of drilling wells according to paragraphs. 1 and 2, characterized in that the laser welding of drill pipes is carried out simultaneously with drilling, and the drill pipe rotates about its own axis, and the laser beam is lowered to a distance equal to the drilling depth per revolution of the drill string.
