Screening method and device for green development schemes of shale gas

Abstract

The invention discloses a screening method and device for green development schemes of shale gas. The method comprises the steps of S110, building a multi-layer target optimization model according to the actual condition in a shale gas exploitation process, wherein the multi-layer target optimization model comprises an upper-layer production target model, a middle-layer environment target model and a lower-layer economic target model; S120, solving the upper-layer production target model, the middle-layer environment target model and the lower-layer economic target model to obtain a result of the upper-layer production target model, a result of the middle-layer environment target model and a result of the lower-layer economic target model; S130, judging whether the result of the upper-layer production target model, the result of the middle-layer environment target model and the result of the lower-layer economic target model are equal or not, if yes, ending the process, and if not, entering the step S140; and S140, performing comprehensive solution on the upper-layer production target model, the middle-layer environment target model and the lower-layer economic target model by using an interactive solution algorithm of fuzzy satisfaction to obtain an optimal solution of the multi-layer target optimization model.

Description

technical field [0001] The invention relates to the technical field of shale gas development, in particular to a screening method and device for green shale gas development schemes. Background technique [0002] At present, the optimization decision-making of shale gas development usually adopts single-objective or dual-level coupled-objective planning. Complexity, the current shale gas development process involves at least three objectives of production management, environmental management and economic benefit management, and decision makers at each level only focus on a specific goal, resulting in conflicts of interest in reality In this context, the optimal strategy of the shale gas green development plan obtained by the traditional single-level planning or dual-level coupling planning technology is quite different from the actual situation, and the practicability is low. Contents of the invention [0003] Based on this, it is necessary to provide a screening method an...
