为了满足高压喷射钻井新工艺的需要,华北油田钻井工艺研究所和上海东风机器厂联合进行了两用水龙头的研制工作。1978年底由上海东风机器厂完成了4台样机。1979年开始在华北油田3个井队进行试验,效果很好,受到钻井工人的欢迎。同年5月在华北油田召开SL130/20Q两用水龙头产品鉴定会,决定投入小批量生产。 In order to meet the needs of new technology of high-pressure jet drilling, Huabei Oilfield Drilling Technology Research Institute and Shanghai Dongfeng Machinery Factory jointly developed a dual-purpose faucet. By the end of 1978, Shanghai Dongfeng Machine Works completed four prototypes. Since 1979, three wells in Huabei Oilfield have been tested with good results and are welcomed by drilling workers. The same year in May held in North China Oilfield SL130 / 20Q dual-use faucet product identification meeting, decided to put into small batch production.
