摘要:
基于目前油气田企业用能系统能效评价存在界限不清晰、评价方法不完善的问题,通过重点用能系统能耗构成及用能评价现状的分析,结合相关现行标准,建立了一套界限清晰、用于合理表征油气田企业重点用能系统用能水平的能效指标体系,涵盖3个层级16项指标,确定各项指标的测试和计算方法,并提出基于矩阵运算的能效加权综合评价方法,用于进行系统能效水平的纵向、横向对比。以塔里木油田6个站场系统为例,将目前常用的评价方法与提出的综合方法进行效果对比,验证该套指标体系及能效加权综合评价方法能够更加合理地反映相应系统的能效水平,并为后续节能改进措施的提出及相关节能工作开展提供依据。通过应用效果分析,发现现行标准中存在指标限值划分不细致、无法覆盖所有典型工况等问题,进而提出标准后续待修订完善的方向,以保证标准的合理性、适用性和先进性,有效促进相关节能管理工作的持续改进和提升。

Abstract:
In view of the current problems of unclear boundaries and incomplete evaluation method for energy efficiency evaluation of energy consumption systems in oil and gas field enterprises, a set of energy efficiency index system with clear boundaries used for reasonable characteristic of the energy efficiency was established by analyzing the energy consumption structure and evaluation status of the energy consumption system combined with the relevant current standards. The energy efficiency index system covers 16 indicators at three levels. The testing and calculating methods of these indicators were determined and a weighted comprehensive evaluation method of energy efficiency based on matrix operation was proposed for the vertical and horizontal comparison of the system energy efficiency level. Taking six stations in Tarim oilfield as an example, the results of the current common evaluation methods were compared with those of the comprehensive methods proposed, to verify the rational reflection of the index system and weighted comprehensive evaluation method for the energy efficiency level of the corresponding systems. The example could also provide the basis for the improvement of energy conservation measures and the related energy conservation work. Through the analysis of application effect, it was found that there are some problems in the current standards, such as the lack of detailed classification of index limits and the inability to cover all typical working conditions. And then the future direction of the standard to be revised and improved was proposed in order to ensure the rationality, applicability and advancement of the standards, and to promote the continuous improvement for related energy-saving management work.
