[0018] according to Figure 1-3As shown, a deep well drilling rig with high stability comprises a frame, a drilling rig boom 4 is rotatably mounted on the top of the frame, the drilling rig boom 4 is a telescopic structure, a front supporting leg is rotatably mounted on the front end of the frame, and a telescopic rear supporting leg is provided at the rear end, the front supporting leg and the rear supporting leg are both provided with hydraulic support legs 2, a moving crawler 1 is installed on the bottom of the frame, the drilling rig boom 4 is mounted on the frame through a rotating shaft 9, and the side of the drilling rig boom 4 away from the power head 5 is connected to the output end of the diagonal support cylinder 3, and the diagonal support cylinder 3 is mounted on the frame.

[0019] In the above specific embodiment, by setting up a mobile crawler 1, the movement of the frame is facilitated, and the crawler has strong adaptability to various terrains, which increases the applicability of the device. The front support legs are rotatably installed on the frame. When the terrain is more complicated, the front support legs can be rotated to find a relatively flat supporting ground to increase the stability of the support. The rear support legs can be retracted, which is beneficial to increase the supporting area of ​​the frame and further improve the stability of the support. Hydraulic support legs 2 are provided on the front and rear support legs, and the frame is lifted by the hydraulic support legs 2 to provide stable support. Preferably, the hydraulic support legs 2 can lift the frame by 1700mm, which is convenient for lifting the device onto a transport vehicle for loading and transportation. A supporting cylinder 16 is provided at the bottom of the drilling rig boom 4 to increase.
