Pressure test drill rod for well drilling construction

The utility model relates to the field of well drilling, and discloses a pressure test drill rod for well drilling construction, which comprises a base and a rod part, the upper surface of the base is fixedly connected with the rod part, the upper surface of the base is provided with a buffer piece, and the buffer piece is arranged on the peripheral side of the rod part. According to the utility model, the buffer piece is arranged, so that the collision time between the pressure test drill rod base and the flashboard in the pressure rising process is prolonged, the interaction force when the pressure test drill rod base is in contact with the bottom surface of the flashboard assembly is reduced, the vibration degree of the pressure test drill rod is reduced, and the thread structure of the pressure test drill rod is protected. 本实用新型涉及钻井领域，公开了一种钻井施工用试压钻杆，包括底座和杆部，底座上表面固接有杆部，底座的上表面设置有缓冲件，缓冲件设置在杆部的周侧。本实用新型通过设置缓冲件，使得起压过程中试压钻杆底座与闸板之间碰撞时间增大，使得试压钻杆底座与闸板总成底面接触时的相互作用力降低，减少了试压钻杆的振动程度，实现对试压钻杆螺纹结构的保护。
