我校开发系沈忠厚教授领导的射流科研组1982年承担了原石油部“提高射流井底效率研究”课题。1982～1985年,该科研组从研究射流动力学理论入手,在理论上取得突破性进展。其理论成果分别在第二届国际石油工程会议和美国《SPE钻井工程》杂志上发表,受到国际同行专家的关注和好评。1985年下半年,根据取得的理论成果,设计了加长喷嘴牙轮钻头,与
In 1982, the Jet Research Team headed by Professor Shen Zhonghou, our department of development, assumed the task of “Researching the Improvement of Jet Bottomhole Efficiency” of the Ministry of Petroleum. From 1982 to 1985, the research group started with the study of jet kinetics theory and made breakthroughs in theory. Its theoretical achievements were published in the 2nd International Petroleum Engineering Conference and the SPE Drilling Engineering Magazine in the United States, respectively, and received the attention and praise of international counterparts. In the second half of 1985, according to the theoretical results obtained, a longer nozzle cone roller bit was designed
