Environmental Risk Assessment Of Oil Field Development Area Based On Spatial Information Diffusion Method

In recent years, along with some large oil industrial base planning, regional development of oil field is moving in large-scale, integrated trend. On the environmental risk assessment of individual fields has also been planning over the environmental risk across the field. An environmental risk assessment, regional environmental risk assessment should consider the relationship between the construction project within the planning area and the adjacent area environmental factors. Evaluate the safety and reasonable layout to minimize the risk from environmental perspective. In the oil field development cycle, the intensity level of the risk of accidents and damage to the environment is not quite the same. For this reason, the development of oilfields unreasonable, would soil, rivers and groundwater pollution. How to reduce the environmental risks posed by the regional development is an important task of promoting the sustainable development of oil fields.This article will expand spatial information law for regional development environmental risk assessment oilfield, building three-dimensional model of the research method chosen natural factors, accident factors, human factors three factors to build a total of 12 specific indicators oilfield regional development indicators. Determine the index weight, by constructing the indicators, it presented a perfect area for oil development of risk assessment management system AHP. Use of space combined with the programming language Matlab model for the development of tools, reference standards at home and abroad to determine the environmental risk assessment rating(very high, high, medium, low, very low).This paper takes a representative of an oilfield case studies, by predicting the field of regional development in environmental problems, given the appropriate measures, proposed preventive measures. Provide technical support to the study of regional development for the oilfield environmental risks of future accidents oilfield development plays an absolutely essential meaning and value.
