RJ-500型柔杆钻机是我国第一台研究柔杆钻井设备及工艺的科研性配套试验样机,由广东省柔杆钻机研制组负责研制,并于一九七二年列为第一机械工业部重点科研项目,一九七三年——一九七四年,由中国科学院科技办公室列为全国重点科研项目。其主要研制目的,是使用柔杆、钻探电机及其地面机电设备钻深500米,摸索柔杆钻进工艺,为柔杆钻井设备的设计、制造、使用方面积累经验和提供数据。通过研制组的多年努力,已基本达到了原订科研目的。
The RJ-500 soft-rod drilling rig is the first scientific research supporting prototype for researching soft-drilling drilling equipment and technology in China. It was developed by the Guangdong Flexible Rod Rig Development Group and was listed as the first machinery industry in 1972. Ministry of key scientific research projects, 1973 - 1974, by the Chinese Academy of Sciences Science and Technology Office as a national key scientific research projects. The main purpose of its development is to use flexible rods, drill motors and ground mechanical and electrical equipment to drill a depth of 500 meters, to explore flexible rod drilling techniques, and to accumulate experience and provide data for the design, manufacture and use of soft rod drilling equipment. Through the efforts of the research team for many years, the purpose of the original research has been basically achieved.
