Risk Assessment Of Shale Gas Development In Sichuan-Yunnan Region Based On Fuzzy Evaluation Method

In recent years,the development of shale gas has achieved rapid development in our country,and the Sichuan and Chongqing area is the key development areas.The Sichuan and Chongqing area is rich in shale gas resources,oil enterprises actively develops the shale gas industry here.Although the Shale gas development enterprises have made some good results,they also faced with many uncertainties and various risks.How to effectively identify,evaluate and deal with these risks is the hot issues that the Sichuan and Chongqing area shale gas development enterprises widespreadly attention and need to be solved.Therefore,this article from the perspective of shale gas development enterprises to study the Sichuan and Chongqing area shale gas development risk,which heve great theoretical and practical significance in dealing with risks and promoteing the healthy development of the shale gas industry.Based on the systematic review in risk of shale gas development in the Sichuan and Chongqing area present situation,this paper integrated application of the risk theory and fuzzy comprehensive evaluation method to analyze the risk of shale gas development in the Sichuan and Chongqing area,the main work and conclusions are as follows:1.Through expert investigation,shale gas development risk factors in the Sichuan and Chongqing area are identified,the Sichuan and Chongqing area shale gas development risk index system is constructed,the risk of the Sichuan and Chongqing area shale gas development multistage fuzzy comprehensive evaluation model is established.2.Through questionnaire,collecting the related data about the risk on shale gas development in the Sichuan and Chongqing area analysing the risk,and concluded the risk level,put forward the management risk of countermeasures and suggestions.
