Computation and evaluation method research on oil/gas energy consumption

Based on existing oil and gas pipeline simulation systems, the energy consumption software and its assist function are developed, which is used for measuring energy consumption under the conditions of different seasons and different throughputs. Using risk assessment method, the best technology under certain transmission amounts is given. Combined with the inputoutput theory, the priority order of energy saving reconstruction of pipeline is presented. According to the method of running time weighted on different schemes, the comprehensive investment income index of equipment is got and sorted, and an energysaving modification is finally obtained.Based on the evaluation method and using the energy consumption simulation system of oil/gas pipelines, the current running schemes adopted in Lanzhou-Chengdu-Chongqing Products Oil Pipeline, West-to-East Gas Pipeline and Alashankou-Dushanzi Crude Oil Pipeline are evaluated and the relatively optimal operation plan is given.
