From the viewpoint of system engineering ,the navigation safety of oilfield water is analyzed and the quantitative evaluation indexes are identified. The comprehensive evaluation model is built to evaluate the navigation safety of oilfield water according to the butterfly catastrophe theory. Then the safety management measures are proposed to improve the navigation safety. This evaluation method is simple, reliable, convenient and easy. The navigation safety of oilfield water is reflected objectively on the basis of the actual statistics. It can reduce the impact of subjective factors. It provides a reliable theoretical support for the navigation safety of oilfield water, so that to protect the navigation safety of oilfield water. In the form of marine industry, marine oil and gas development is emerging marine industry. With the development of petroleum technology, oil field operation area of existing oil and gas development has been unable to meet the demand, the development of offshore oil and gas to enter the deep waters, waters oilfields will gradually cover customary route and route the port waters, oil group waters ship traffic increased, marine traffic environment, increase the risk and consequences of complex navigation accident on water the pollution is more and more serious phenomenon, but also so much authority and social concern. Analysis and Research on Oilfield Group waters navigation safety state route has important practical significance for the realization of safe navigation route waters oilfields. With the oilfield waters complicated traffic environment intensifies, at present, the corresponding research is mainly reflected in the drilling platform, influence on navigation safety, safety operation area of Bohai oilfield oil platform area maritime supervision mode and the habit of oilfield route planning were studied. This article from the perspective of traffic analysis and evaluation of traffic safety in oilfields water route, puts forward suggestions for safety management, to ensure the safety of navigation route waters oilfields.
