Abstract
With the development of oil and gas exploration and development to a deeper,more complex and more extreme environment,engineering technology progress has become the core driving force to break through the triple limits of geology,environment and economy.In recent years,with the increasing importance of intellectual property rights,applicants have made more applications and layouts in the field of oil and gas wells,forming a large number of patented technologies.Based on patent information,the number of applications,authorizations,applicants,inventors,laws,operations,and technical analysis in the field of oil and gas wells are analyzed to promote technological innovation in the field of oil and gas wells.关键词
