(Lanzhou Petroleum Chemical Machinery Works, Lanzhou 730050, China) Abstract:on the basis of summarizing the technical practice of oil drilling rig from U.S., analyzed the technical notation of the main parameters of the reviewed standard and discussed in detail the rationality and advancement of the standard

Key words：standard; technique; analysis; Conclusion ▲ 1 standard formulation and revision review the vigorous development of China's petroleum industry in the 1970s, but the equipment is backward. Under this situation, the former Ministry of petroleum industry and the Ministry of machinery industry jointly organized and established the "drilling rig serialization and chain drilling rig investigation group" in 1975, and the "three standardization group" in 1978. Based on the analysis of drilling rig standards in various countries and American drilling rig and API specifications, China drafted the standard of oil rig types and basic parameters. It was reported to the State Administration of standards in 1979 and approved as the national standard of the people's Republic of China with the standard number of gb1806-79, which was implemented on

the remarkable technical feature of this standard is that it breaks through the previous practice of following the standards of the former Soviet Union and Romania in terms of the maximum hook load parameters. These two standards basically determine the maximum hook load according to the needs of casing load in the comprehensive well structure; China's standard this time is to determine the maximum hook load by giving full play to the load that can be provided by the winch of the drilling rig under the requirements of relevant specifications and design criteria. Therefore, this parameter formulated by this standard is larger than that of the Soviet Union and Romania standards (see Table 1), which greatly improves the adaptability of the drilling rig to the formation and drilling technology.

Basic practices of American oil drilling rig technology. The United States ranks first in the world in terms of oil drilling rig technology and sales volume. The integration with international technology is essentially the integration with the technical practices represented by the United States and the adoption of API specifications. This trend has been adopted in the standards of oil drilling rigs in China

as far as the commonly used mechanical driven drilling rigs are concerned, the United States has reached a mature stage in the 1960s, and its petroleum machinery manufacturing industry has developed rapidly from that time to the 1970s. There are eight major drilling rig manufacturing companies. According to statistics, 1891 drilling rigs were used by 286 land and 40 offshore drilling companies in the United States in 1973, accounting for 90%, especially national, emsco and IDEO, which accounted for 30.8%, 13.9%, 10.7%, oil well 8.25%, mid continent8.25%, Wilson 7.15%, cardner Denver 5.15% and Brewster 4.85% respectively
