The invention relates to petroleum drill and exploitation equipment, in particular to a trip drilling rig, a trip method and a continuous trip method. The trip drilling rig comprises a first driving device, a linkage device, an upper lifting device, and a lower lifting device, the upper lifting device comprises a lifting drive, the lower lifting device comprises a power slip for clamping a drill string, the upper lifting device and the lower lifting device can be close to or away from each other in a height direction of the trip drilling rig, the first driving device is connected with the upper lifting device or the lower lifting device, the upper lifting device and the lower lifting device are connected through the linkage device, so that when the upper lifting device moves, the lower lifting device moves along with the upper lifting device. According to the trip drilling rig, the trip method and the continuous trip method, the upper lifting device and the lower lifting device are arranged, and the upper lifting device and the lower lifting device can work cooperatively, so that the stroke of one single lifting device in a one-time trip process is shortened, and efficiency improvement is facilitated.

    本发明涉及一种石油钻采设备,具体涉及一种起下钻钻机、起下钻方法及连续起下钻方法。该起下钻钻机包括第一驱动装置、联动装置、上起升装置和下起升装置;上起升装置包括顶驱;下起升装置包括用于卡接钻柱的动力卡瓦,上起升装置和下起升装置能够在起下钻钻机的高度方向上相互靠近或远离;第一驱动装置与上起升装置或下起升装置相连,上起升装置与下起升装置通过联动装置相连,使得可以实现在上起升装置移动时,下起升装置随上起升装置一起移动。本发明提供的起下钻钻机、起下钻方法和连续起下钻方法,设置了上起升装置和下起升装置,上起升装置和下起升装置能够配合工作,从而缩短在一次起下钻的过程中单个起升装置的行程,有利于提高效率。
