Quantitative identification method for rationality of well row spacing in shale oil horizontal well development

The invention discloses a shale oil horizontal well development well row spacing rationality quantitative identification method. The method specifically comprises the steps that a shale oil horizontal well development recovery ratio prediction model is established; the recovery ratio of the shale oil reservoir depletion-type development full life cycle is calculated through the development recovery ratio prediction model by utilizing the basic high-pressure physical property parameters of the in-situ crude oil and gas and the average pore volume compression coefficient of the rock core; according to the production dynamic data of the target block, shale oil elastic development single well recoverable reserves are calculated; calculating single-well control geological reserves and converting single-well control radiuses according to the calculated shale oil elastic development single-well recoverable reserves and recovery ratios; and according to the single well control radius, calculating a well row spacing r
