NOVELTY - The utility model claims a petroleum exploitation wearable reinforcing sealing packing, belonging to the sealing packing technology field, comprising a graphene packing ring, the inner wall of the graphene packing sequentially is provided with three groups of rolling sealing groove from up to down, the rolling sealing groove is provided with a rolling sealing component; the sealing rolling component comprises a rotating supporting rod set on the inner wall of the rolling sealing groove, and the outer part of the rotating supporting rod is rotatably connected with the upper graphene ring through a bearing. The utility model is provided with a rolling sealing component, the polished rod is inserted into the gap formed between the seventeen rubber buffer rings, the three groups of rubber buffer rings can be surrounded at the outer position of the polished rod, the rubber buffer ring drives the graphene rotating ring to support and rotate, the petroleum is divided into three layers of sealing contact and the sliding friction between the light rod and the rubber buffer ring is changed into rolling friction, which effectively improves the wearable strength of the sealing packing.
