The invention belongs to the technical field of ultra-low permeability reservoir reform, and particularly relates to a horizontal well volume fracturing tubular technological column and method based on conventional oil tube pressure dragging. The horizontal well volume fracturing tubular column and method are used for oil horizontal well volume fracturing technology. A conventional oil tube is adopted for conveying, a packer packs a constructed layer, hydraulic sand blasting perforation is carried out through hydraulic sand blasting, a ground annular preventer and a fracturing tree pressure dragging tubular column are combined to achieve oil and gas horizontal well continuous subsection volume fracturing construction, the problems that in an existing volume fracturing construction technological process, tubular column dragging operation can be carried out by releasing formation pressure, construction time is prolonged, and the constriction cost is increased are solved, construction time is shortened, construction efficiency is improved, and the construction cost is reduced.
