The invention relates to a continuous oil pipe clamping device and an injection head adopting the same. The inner surface of a clamping block of the clamping device is a clamping opening in a trapezoid-like shape. The bottom of the clamping opening is in a circular arc shape. Clamping ridges and grooves are distributed on the two sides of the clamping opening alternately. The clamping ridges comprise the plastic clamping ridges and the rigid clamping ridges, and the plastic clamping ridges and the rigid clamping ridges are arranged at intervals and distributed alternately. By means of the continuous oil pipe clamping device, abrasion of the inner surface of the clamping block and damage to continuous oil pipes can be reduced, meanwhile, the oil pipe clamping force of the clamping block can be increased, the operation effect and working efficiency of equipment are improved, and the service life of the equipment is prolonged.
