A computer implemented method for determining an integrated exploitation approach for a shale and adjacent oil reservoirs, characterized by comprising: determining a thickness of an effective shale, thicknesses of adjacent effective oil reservoirs to the effective shale, and a planar distribution area of the effective shale and the adjacent effective oil reservoirs to the effective shale, based on logging data of a target reservoir of interest; determining a top effective boundary of the adjacent effective oil reservoirs above the effective shale, and a bottom effective boundary of the adjacent effective oil reservoirs below the effective shale, based on the thickness of the effective shale, the thicknesses of the adjacent effective oil reservoirs to the effective shale, and the planar distribution area of the effective shale and the adjacent effective oil reservoirs to the effective shale; determining a maximum seepage radius of each of the adjacent effective oil reservoirs to the effective shale, based on a formation pressure, a fracture pressure and a starting pressure gradient for starting fluid seep of the adjacent effective oil reservoir; determining a well pattern for integrated exploitation of the effective shale and the adjacent effective oil reservoirs based on the thickness of the effective shale, the top effective boundary, the bottom effective boundary and the maximum seepage radius; determining a well completion approach according to the well pattern for integrated exploitation; and determining a total number of perforation clusters of gas injection wells, a number of perforation clusters corresponding to each of the adjacent effective oil reservoirs, a gas injection amount per unit time of each of the perforation clusters, and a total gas injection amount per unit time of the gas injection wells, according to the well completion approach; wherein the effective shale is in communication with all the adjacent effective oil reservoirs by boring-through of a fluctuating horizontal well or a vertical well; wherein the effective shale is a shale satisfying conditions of in-situ conversion and exploitation, the adjacent effective oil reservoirs are oil reservoirs, which satisfy lower limit values of porosity ( φ), permeability and oil saturation (So) that are acquired based on the logging data, in adjacent oil reservoirs above and below the effective shale; the top effective boundary is a top boundary of the topmost adjacent effective oil reservoir above the effective shale; and the bottom effective boundary is a bottom boundary of the bottommost adjacent effective oil reservoir below the effective shale. determining a thickness of an effective shale, thicknesses of adjacent effective oil reservoirs to the effective shale, and a planar distribution area of the effective shale and the adjacent effective oil reservoirs to the effective shale, based on logging data of a target reservoir of interest;
