The invention provides an annular preventer for drilling and workover in an oil field, belonging to the technical field of drilling equipment. The annular preventer for drilling and workover in the oil field comprises an upper end cover, a shell and a preventer core, wherein the upper end cover is assembled with the shell through a bolt component; the preventer core is arranged in a cavity enclosed by the upper end cover and the shell; a slip assembly, a vertically-arranged packing element and a rigid torsion transfer drum are arranged in the preventer core; a packing element upper torsion conduction shaft and a packing element lower torsion conduction shaft are respectively arranged at the upper and lower ends of the packing element; the packing element upper torsion conduction shaft is of a hollow structure, and the inner wall of the packing element upper torsion conduction shaft is a circular conical surface matched with the slip assembly; and the torsion transfer drum sleeves outside the packing element. The annular preventer for drilling and workover in the oil field has the characteristics of strong high pressure resistance, good universality and long working life and is suitable for conventional down-hole operation, operation under pressure and under-balanced drilling operation.
