The invention relates the method for improving atmospheric and vacuum distillation light oil productivity. The method comprises the following step: adding the 0.001-0.1wt% addition agent with colophony into crude oil in atmospheric and vacuum distillation tower. The addition agent comprises 50-80% colophony and 50-20% organic solvent. The pH is 7.0-7.5. The organic solvent comprises ethanol or cellosolve or ethyl propyl acetone or acetate cellosolve. The method can be used in oil-extraction plant, and the light oil productivity is improved by 1.5-2.3wt%.

The invention relates to detachable-mountable arc-shaped precise positioning equipment, which includes a supporting unit, a three-dimensional regulating unit connected to the supporting unit, and a guidance positioning unit. The guidance positioning unit includes an arc-shaped rail, a guide rod, a holder, and positioning meters. A second sliding block is connected to the three-dimensional regulating unit; the arc-shaped rail is arranged and slides on the second sliding block, and can be subjected to in-situ rotation around a vertical axis at any angle; the three-dimensional regulating unit drives the arc-shaped rail to move in three dimensions of up-down, left-right, and front-back dimensions; the guide rod can slide along the arc-shaped rail and moves long a long axial direction of the guide rod; and the holder is arranged on the guide rod for fixing a surgical instrument. There are two positioning meters, and rays sent by the two positioning meters, along with a long axis of the holder, are parallel to or coincide with a radial line of the arc-shaped rail. The three lines are located on a same plane, which is parallel to or coincide with the plane where the arc-shaped rail is located. The three lines intersect at one point.
