Method for evaluating shale oil seepage characteristics according to strata density

The invention discloses a method for evaluating shale oil seepage characteristics according to strata density, which comprises the following steps of: on the basis of comprehensively analyzing geology and logging information, determining the top and bottom depths and thicknesses of main small strata in a research block, screening key logging curves, and determining the number of strata by using a second derivative derivation method; and determining the change of the density of the corresponding grain layers according to the number of the grain layers and the thickness ratio. Regional seepage characteristic evaluation is carried out through density change rules of different small lamina layers in a target area, and a feasible technical method is provided for shale oil development.

Flat-lying type eye periphery massage instrument for eye nursing

The invention discloses a lying type eye care periocular massage instrument, and relates to the related field of eye health care tools, the lying type eye care periocular massage instrument comprises a periocular massage instrument, a controller mounted in the middle of the right end of the periocular massage instrument, and fixing belts fixedly inserted in the left and right parts of the rear end of the periocular massage instrument; the double-shaft motor indirectly drives the L-shaped rod to slide backwards through the transmission rod, so that the L-shaped rod drives the canthus massage head and the circular massage head through the mounting plate to press the peripheries of the eyes of the user, and meanwhile, the electric heating wire plays a role in hot compress of the eyes of the user; the problems that the efficiency is low and the blood circulation of the eyes is difficult to effectively promote when the eyes of the user are massaged only through the convex massage contacts are ...
