Embodiment Construction
[0049] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0050] Such as Figure 1 to Figure 5 As shown, a land continuous tripping drilling rig includes a base 1, a main drilling system 2 and a driller's cabin 5, and also includes a continuous tripping system 3 and a pipe handling system 4;
[0051] The main drilling system 2 includes an upper derrick 21, a lower derrick 22, a main hoisting mechanism 23, a crown block 24, a top drive 25 and a drilling wire rope 26. The lower derrick 22 of the frame structure is connected with the upper platform of the base 1, and the upper derrick 21 is assembled on the lower derrick. The slide rail on the inner wall of 22 moves up and down along the lower derrick 22, and the top of the upper derrick 21 is fixedly equipped with a crown block 24; Fixed on the lower derrick 22; one end of the drilling wire rope 26 is connected to the top drive 25, and the other end is connected to the dead ...

The invention discloses a land continuous tripping drilling machine and a continuous tripping operation method. The drilling machine comprises a base, a main drilling system, a continuous tripping system, a pipe treatment system and a driller room, wherein the main drilling system comprises an upper derrick, a lower derrick, a main lifting mechanism, a crown block, a top drive and a drilling steel wire rope, and the upper derrick and the lower derrick are connected with each other in a sleeved mode; the continuous tripping system comprises a continuous tripping device, an auxiliary lifting hydraulic cylinder and an auxiliary lifting steel wire rope, the continuous tripping device is located below the top drive, and a pulley device is arranged on the upper part of the auxiliary lifting hydraulic cylinder; and the pipe treatment system comprises a power catwalk, a power pipe arranging frame, a pipe arranging machine and a power finger board. Through the use of the land continuous tripping drilling machine, the onsite pipe moving and shackling operations are completed by the matched pipe treatment system and the continuous tripping system, the physical labor intensity of onsite workers is greatly reduced, a drill column can keep moving continuously, the influence on underground pressure fluctuation is reduced, the stability of a well hole is improved, and the possibility of underground accidents is reduced.
Description
technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a land continuous tripping drilling rig and a continuous tripping operation method. Background technique [0002] The current level of automation of land drilling rigs is relatively low. During the drilling operation, intermittent tripping is adopted, the drill string is clamped at the turntable, and iron drillers or hydraulic tongs are used to make up and break out. After the operation is completed Using the top drive to lift or lower the drill string, the drill string moves intermittently, resulting in long processing time and low operating efficiency, and the intermittent lifting or lowering of the drill string is likely to cause pressure fluctuations in the well and increase the possibility of downhole accidents. Contents of the invention [0003] The purpose of the present invention is to provide a land continuous tripping drilling rig and a continuous tripping ...
