Research On Robust Control Of Overseas Oil Engineering Project Based On The Catastrophe Theory

In recent years, most major oilfield entered middle and later periods gradually inour country. Exploration and development are more and more difficult. It is unable tomeet the resource demand of economic development just relying on domesticpetroleum engineering. The importance of overseas oil is increasingly prominent. Inunknown country, investing ourselves in oil industry undoubtedly face a greater risk.Especially, various emergencies happened frequently brings huge losses of human andfinancial resources to petroleum engineering projects, which are invested by ourpetroleum enterprise. The construction and operation in petroleum engineeringprojects are a large investment, long cycle, complex technology, high risk of systemsengineering. As one of the important attributes of the projects, robustness determinesits stable operation or not. In order to ensure the implementation of petroleumengineering construction, we should assess and analyze the robustness of investmentproject using a scientific method, providing the scie ntific basis for the team’sdecisions. For the purpose, we will study and discuss as followed:（1）Early-stage preparations. Firstly, we should collect and review relatedliterature. According to project management theory, the robust control theory andcatastrophe theory, we systematically summarize the research status, developmenthistory, basic conception and principle theory and principle foreshadowing for thefollow-up study. Secondly, we analyze current situation of overseas oil project robustcontrol, divide the internal emergency from the perspective of typology as the base forlater evaluation index selection. At the same time, identify the factors affecting therobustness of overseas oil projects, search and analyze the current existing problemsas to get the research starting point and the foothold.（2）Theoretical research. In one hand，in order to conduct quantitative evaluation for oversea oil engineering robust control status, we design robustnessevaluation system of overseas oil projects by determining the evaluation function andthe selection of evaluation indexes. And we details of the system operation steps. Inthe other hand, on the base of qualitative analysis and quantitative evaluation foroversea oil engineering robust control status, we will get the control variables andstate variables by using catastrophe theory. Combined with overseas oil projectcharacteristics, we will modify the cusp catastrophic model, and build robust controlmodel of the mutation for overseas oil projects. Explain robust control analysispatterns of the model.（3）Case analysis. Taking some oversea oil engineering as an example, we usethe evaluation system and mutation model respectively to its robustness evaluationand deductive analysis, providing examples in practical application.（4）Recommendations and conclusion. In the light of research contents, weoffer general countermeasure and suggestion to robust control of overseas oil projects,and summarizes the research conclusion of this article.
