石油天然气总公司新技术公司于1991年5月15日至19日在胜利油田召开了“新技术推广成果评审验收会”。本次会议共有11个单位29个项目参加了验收。我校沈忠厚教授等研制的“加长喷管牙轮钻头”项目经专家、评委评审、顺利通过验收,并给予了较高评价。 会上,专家们一致认为,加长喷管牙轮钻头的研制在国内处于领先水平。它不仅从理论上解决了以井底获得最大水功率为目标函数的水力参数设计程序这个在石油钻井中长期未解
The new technology company of the Oil and Gas Corporation held the “Evaluation and Acceptance Examination of New Technology Promotion Achievements” in Shengli Oilfield from May 15 to May 19, 1991. This meeting a total of 11 units 29 projects participated in the acceptance. The project of “Lengthening nozzle cone roller bit” developed by Professor Shen Zhonghou of our university was evaluated by experts and judges and successfully passed the inspection and acceptance and gave a high appraisal. At the meeting, experts agreed that the development of a longer nozzle cone bit in the leading domestic level. It not only theoretically solves the design process of hydraulic parameters with the objective of obtaining the maximum water power at the bottom of the well, which has not been solved for a long time in oil drilling
