Oil pipe heating and heat preservation cover and coiled tubing operation vehicle

The invention relates to the field of coiled tubing construction operation, in particular to an oil tube heating and heat preservation cover and a coiled tubing operation vehicle. The oil pipe heating and heat preservation cover comprises a cover body used for being fixed to a base plate to cover a roller, the cover body is provided with a downward opening, a zipper is arranged at the top of the cover body and comprises a zipper belt extending in the axial direction of the roller and two pull heads, a penetrating space allowing a coiled oil pipe to penetrate through is formed between the two pull heads, and the two pull heads are connected together. When one pull head pulls open the chain belt under the action of the coiled tubing, the other pull head pulls the chain belt to be closed; and a heating piece for heating the coiled tubing wound on the roller is arranged on the cover body. The continuous oil pipe wound on the roller is heated and subjected to heat preservation, meanwhile, ascending and descending
