Current Situation and Development Suggestions of Uncontrolled Blowout Emergency Response Technologies at Home and Abroad
Uncontrolled blowout is a catastrophic accident in international oil and gas exploration and develop-ment,which would bring large property loss,environmental damage and negative social impact.In order to mini-mize the loss or impact caused by the uncontrolled blowout,the emergency response technology has been devel-oped.The development status of emergency response technologies at home and abroad is described,and the advan-tages and gaps of various technologies are analyzed.The results show that the domestic blowout control rescue technologies have developed rapidly in the past 30 years,and the technical equipment and operation ability have reached the international leading level.According to the trend of oil and gas exploration and development,it is be-lieved that technological breakthroughs should be made from the aspects of high-pressure and high-yield oil and gas injection diffusion and interference impact,temperature field distribution around uncontrolled well,and visual-ization near wellhead,etc.,and high-efficiency hydraulic sandblasting cutting equipment,long-distance flame cut-ting equipment,and miniaturized emergency equipment should be upgraded,so as to continuously promote the de-velopment of emergency response technology for uncontrolled blowout and meet the needs of emergency response under extremely harsh conditions.
