【摘要】：油田企业的油气资源开发活动一方面为工业发展提供基本的能源和物质来源，另一方面油气资源的勘探和开发对原有的自然生态环境系统造成了一定的影响，使油田生态环境系统与外界生态系统之间失去了平衡，物质和能量循环过程进一步加速，日益增多的生态环境问题制约着油田生态环境系统的持续、健康、稳定发展。本文首先分析和研究了油田企业生态环境系统的基本理论和系统动力学的基本原理及方法，在明确了油田生态环境系统评价指标体系构建的原则和依据的前提下，对胜利油田生态环境系统的作用机理进行分析，从而建立胜利油田生态环境系统评价指标体系，为下一步系统动力学模型的构建和运用提供可供选择的指标。明确了胜利油田生态环境系统模型构建的思路，确定了系统边界和系统因果关系图；对系统的相关变量进行了说明，构建经济、资源和环境三个子系统的SD模型，，运用胜利油田的数据模拟了三个子系统。建立胜利油田系统动力学模型，依据模型检验的依据，从模拟的真实性和有效性来检验所构建的模型。使用Vensim（PLE）软件，对胜利油田生态环境系统进行模拟，检验模型模拟值与真实值的拟合度；其次，对模型进行动态仿真试验，研究不同政策条件对系统行为产生的影响，预测出模型主要变量的发展趋势，通过分析不同政策方案下的试验结果，为油田生态环境系统决策提供了科学参考。本文结合胜利油田生态环境系统发展的实际，对胜利油田生态环境系统的系统动力学模型进行了应用举例。通过SD模型的构建、检验和模拟仿真，指出胜利油田生态环境系统发展存在的问题和难点。通过对系统行为动态仿真试验，提出胜利油田生态环境系统发展的政策建议，为我国油田企业生态环境系统研究提供了一定的理论和实践意义。
[Abstract]:On the one hand, the exploitation activities of oil and gas resources of oil and gas enterprises provide the basic energy and material sources for industrial development, on the other hand, the exploration and development of oil and gas resources have a certain impact on the original natural ecological environment system. The balance between the oil field ecological environment system and the external ecosystem has been lost, the material and energy cycle process has been further accelerated, and the increasing ecological environmental problems are restricting the sustainable, healthy and stable development of the oil field ecological environment system. This paper first analyzes and studies the basic theory of the oil field enterprise ecological environment system and the basic principle and method of the system dynamics. On the premise of defining the principle and basis of constructing the evaluation index system of the oil field ecological environment system, the paper analyzes and studies the basic theory and the system dynamics of the oil field enterprise ecological environment system. The mechanism of ecological environment system in Shengli Oilfield is analyzed, and the evaluation index system of ecological environment system in Shengli Oilfield is established, which can be used as an alternative index for the construction and application of system dynamics model in the next step. The idea of constructing ecological environment system model in Shengli Oilfield is clarified, the system boundary and system causality diagram are determined, the related variables of the system are explained, and the SD model of three subsystems of economy, resources and environment is constructed. The data of Shengli Oilfield are used to simulate three subsystems. The system dynamics model of Shengli Oilfield is established. According to the basis of model test, the model is verified from the authenticity and validity of simulation. The simulation of ecological environment system in Shengli Oilfield is carried out by using Vensimi ple software, and the fitting degree between the model simulation value and the real value is tested. Secondly, the dynamic simulation experiment is carried out to study the influence of different policy conditions on the system behavior. The development trend of the main variables of the model is predicted, and the experimental results under different policies and schemes are analyzed, which provides a scientific reference for the decision making of the oil field ecological environment system. Based on the development of the ecological environment system in Shengli Oilfield, the system dynamics model of the ecological environment system in Shengli Oilfield is applied in this paper. Through the construction, test and simulation of SD model, the problems and difficulties in the development of ecological environment system in Shengli Oilfield are pointed out. Based on the dynamic simulation test of system behavior, the policy suggestions for the development of ecological environment system in Shengli Oilfield are put forward, which provide a certain theoretical and practical significance for the study of ecological environment system of oil field enterprises in China.
