Research On Ecological Environmental System In Shengli Oilfield Based On System Dynamics

The activities of oil and gas resources development in oilfield enterprises on theone hand, provide the basic source of energy and material for the industrialdevelopment. On the other hand, the exploration and development of oil and gasresources have caused a certain effect on the original natural ecological environmentalsystem, making oilfield ecological environmental system out of balance between andoutside ecosystem and further speeding up circulation process of materials and energy.An increasing number of ecological environment problems restrict continuous,healthy and stable development of the oilfield ecological environmental system.At first, this paper analyzes and studies basic theory of oilfield enterpriseecological environmental system and basic principles and methods of systemdynamics. After making principles and basis of evaluation index system constructingof ecological environmental system clear, it analyzes the mechanism of ecologicalenvironmental system in Shengli oilfield so as to establish evaluation index system ofecological environmental system in Shengli oilfield which provides the index for theconstruction and application of system dynamics model. By making the thought ofconstructing the model of ecological environmental system in Shengli oilfield clear, itdetermines the system boundary and causality diagram. It illustrates the relevantvariables of the system and constructs economy, resources and environment threesubsystems of SD model by using the data of Shengli oilfield to simulate the threesubsystems. Dynamics model of Shengli oilfield is based on model testing from theauthenticity and validity of the simulation. By using Vensim(PLE) software,ecological environmental system in Shengli oilfield is simulated to test the degree offitting between simulation value and the true value. Secondly, the model dynamicsimulation testing studies the impact of different policy conditions on the system behavior and predicts the development trend of the main variables. Through theanalysis of testing results under different policy options, it provides scientificreference for the decisions in oilfield ecological environmental system.Combining the actual conditions of Shengli oilfield, this paper gives an exampleof the application of ecological environmental system in Shengli oilfield. Through theconstruction, testing and SD model simulation, it points out the existing problems anddifficulties in the development of ecological environmental system in Shengli oilfield.Through dynamic simulation testing of system behavior, it puts forward policysuggestions on the development of ecological environmental system in Shenglioilfield and has certain theoretical and practical significance for the research onecological environmental system in China’s oilfield enterprises.
