The invention discloses an integrated drillable hydraulic anchor with a safety release. The integrated drillable hydraulic anchor comprises an upper connector, a connecting sleeve and an anchor body. Two ends of the connecting sleeve are connected with the upper connector and the anchor body respectively. Jaws and bow springs are arranged on the anchor body. The integrated drilling hydraulic anchor is characterized by further comprising a support sleeve nested in the upper connector, the support sleeve is fixed within the upper connector through shear pins, an elastic jaw is disposed at the lower end of the upper connector, the inner wall of the connecting sleeve is provided with a clamping groove used for accommodating the outer end of the elastic jaw, and the lower end of the support sleeve is abutted to the elastic jaw so that the outer end of the elastic jaw is clamped in the clamping groove of the connecting sleeve. After the integrated drillable hydraulic anchor with the safety release is mounted on a packer of a construction string, the string can be anchored in construction; the jaws can be automatically reclaimed after pressure in tubing is released; after the string is jammed, balls can be thrown into the tubing for pressure holding, or the tubing release is positively rotated to trip out the upper portion of the string; a drilling string can be tripped in to drill and remove the anchor when necessary.
