摘要: 针对马塞勒斯页岩气供应系统中的经济效益、水资源配置和温室气体减排这3个要素,开发基于生命周期评价的多层规划模型,并设置了高、低钻井和产气的两种规划情景。结果表明,在规划期内,高情景和低情景条件下的产气量分别达到882.31 bcf和472.40 bcf;生命周期耗水量主要用于水力压裂和终端发电;原地处理设施将在废水处理过程中占主导作用,且绝大部分的工艺废水将实现回用;系统平均单位电力的温室气体排放强度、经济效益和用水量将分别达到6.00 kg/MJ、0.48 MJ-1和0.10 gal/MJ。结合TOPSIS多属性决策分析,表明多层方案能够规避传统单目标规划模型偏向性过强等不足,并为决策者提供不同模型规划方案的优劣排放。

Abstract: A life-cycle-evaluation-based multicriteria planning model was developed for the Marcellus shale gas supply system to examine three of its component factors (economic benefit, water resource allocation, and greenhouse gas emission reduction) in two scenarios (high and low drilling production output). The research results show that gas output in the planned lifecycle for the high and low-production scenarios is 882.31 bcf and 472.40 bcf, respectively; the water to be consumed during the lifecycle is essentially for hydraulic fracturing and terminal electricity generation; wastewater treatment will be essentially realized by the on-site equipment, with the vast majority of the production wastewater to be recycled. The system's average greenhouse gas emission, economic benefit, and water consumption per unit of electric power will be 6.00 kg/MJ, 0.48 MJ-1, and 0.10 gal/MJ, respectively. As supported by a multicriteria decision analysis using the TOPSIS method, the multicriteria planning avoids the strong bias of traditional single-criterion planning models and provides decision makers with information about the advantages and disadvantages of different planning models.
