英文摘要：

Oil and gas have long been regarded as key elements for any industrialized country. China＇s economy and social security are largely dependent on oil and gas exploration and development. Nowadays, a great deal of attention has been paid to various ways of efficiently developing oil and gas reserves. This paper presents an overview of research and applications of novel jet techniques in well-drilling, well-com- pletion and fracturing. Supported by the National Natural Science Foundation of China, through years of effort, significant achievements have been made in this area. Not only has the systematic theory of novel jetting been established, but also its application has been proved practical in petroleum engineering. This paper focuses on the topics of the self-resonating cavitating jet, the abrasive water jet, and the supercritical CO2 jet, in respect of theories, applications and prospects.
