摘要:
【目的】在集输管网系统的能效评价中，通常未考虑气藏、井筒对集输管网系统的影响，建立的能效评价体系不够完善，无法直接反映三者之间的相互影响，导致评价结果难以体现整个生产系统的能效水平。东胜气田已进入低产低压阶段，单井产出差异大、液气比高、压降速度变快等问题较为突出，亟需构建一套有针对性的评价方法，发现制约其能效的薄弱环节。【方法】基于现行的相关规范及东胜气田生产工艺，在集输管网系统能效评价的基础上，纳入井筒排采、气藏开发相关评价指标，建立了包含10项指标的气藏-井筒-集输管网系统一体化能效评价指标体系，并确定了指标边界值。根据各项指标的特点，建立了基于层次分析法-熵权法-模糊隶属函数法的能效评价混合算法。【结果】在东胜气田J区块的应用表明，工艺调整前其能效评分仅为58.4分，发现制约系统能效水平的关键因素包括排采效果不达标、压缩机组负荷率及管道输送效率较低。结合生产情况，提出了优化排采工艺、调整管网结构等改进措施，调整后再次评分为81.83分，系统能效提升显著，符合现场实际生产情况。【结论】新建的能效综合评价体系与算法能够较好地反映不同生产工艺下气田的能效水平，指导气田进行有效的工艺调整，表明所建立的能效评价指标体系及评价方法具有可行性。
Abstract:
[Objective] In the past, during the energy efficiency evaluation of the gathering and transportation pipeline system, the influence of gas reservoirs and wellbores on the gathering and transportation pipeline system was not considered. As a result, the established energy efficiency evaluation system was not perfect enough to directly reflect the interaction among these three aspects, making it difficult for the evaluation results to reflect the energy efficiency level of the entire production system. To clarify the energy efficiency level of the production system of Dongsheng Gas Field, a set of integrated energy efficiency evaluation methods for gas field, gas reservoir-wellbore, and gathering and transportation pipeline network is proposed. This method is used to evaluate the energy efficiency level of Dongsheng Gas Field under different technological conditions and identify the weak links restricting its energy efficiency. [Method] Based on the current relevant specifications and the production technology of Dongsheng Gas Field, and in accordance with the characteristics of Dongsheng Gas Field, evaluation indexes related to wellbore drainage and gas reservoir development are incorporated on the basis of the energy efficiency evaluation of the gathering and transportation pipe network system. An integrated energy efficiency evaluation index system of gas reservoir-wellbore and gathering and transportation pipe network system containing 10 indexes is constructed. Combined with the relevant standards and production data of the current gas field production system, the index boundary value is determined. According to the characteristics of each index, an energy efficiency evaluation hybrid algorithm based on the Analytic Hierarchy Process (AHP) and Entropy Weight Method (EWM)-fuzzy membership function method is established. [Result] The application in Block J1 of Dongsheng Gas Field shows that the energy efficiency score before process adjustment is 58.4. Analysis reveals that the key factors restricting the energy efficiency level of the system are substandard discharge and production effect, low compressor load rate, and low pipeline transportation efficiency. After adjustment, the re-evaluation result is 81.83. The system energy efficiency is significantly improved, and the evaluation results are in line with the actual production situation on site. [Conclusion] The constructed energy efficiency comprehensive evaluation system and algorithm can better reflect the energy efficiency level of Dongsheng Gas Field under different production processes, find the weak links restricting the energy efficiency of the gas field, guide the gas field process adjustment, and demonstrate that the established energy efficiency evaluation index system and evaluation method are feasible.
