The invention discloses a composite drive mandrel anchoring casing head and relates to the technical field of wellhead devices, the composite drive mandrel anchoring casing head comprises a casing head shell and an anchoring mandrel unit, a pressurizing hole is further formed in the side wall of the casing head shell, the first end of the pressurizing hole is connected with an anchoring hole part,and the second end of the pressurizing hole extends to the outer side of the casing head shell. The anchoring mandrel unit comprises an anchoring mandrel body, a slip exciting piece, an anchoring slip and an annular piston body, wherein the slip exciting piece, the anchoring slip and the annular piston body are sequentially arranged on the outer side of the anchoring mandrel body from top to bottom in a sleeving mode. The casing head can meet the hanging requirement of a mandrel hanger, after the anchoring mandrel body and the casing head shell are anchored, pipe column shifting can be avoided, and the stability and the reliability of the casing head are improved.
