Research status and prospect of geological environment problems in oil and gas exploitation
With the development of economic construction,the demand for oil and natural gas keeps increas-ing,and the geological environment problems brought by accelerated exploitation become more and more prominent.Therefore,the research on the geological environment problems in the process of oil and gas ex-ploitation has important theoretical significance and engineering application value.On the basis of collecting typical cases and research results of geological environment problems in the process of oil and gas exploita-tion at home and abroad,this paper concludes that land subsidence,induced earthquake,groundwater pollu-tion and formation structure change are the main geological environment problems in the process of oil and gas exploitation.The paper discusses the research results of controlling factors,occurrence mechanism and disaster effect of geological environment problems of oil and gas fields,and summarizes the existing monito-ring methods,prediction methods and prevention measures of geological environment problems of oil and gas fields.Besides,the paper not only puts forward the limitations of existing research on geological envi-ronment problems of oil and gas fields,but also looks forward to the future research direction of geological environment problems of oil and gas fields.
