石油和天然气是现代农业、工业、交通运输业、国防工业的重要原燃料,也是人民生活所必需的燃料之一。重点发展石油和天燃气的地质勘探和钻采是我国四个现代化建设中的一个重要环节。目前,我国钻探所必需的钻杆,特别是钻中、深井所需的高强度钻杆全部都是从国外进口。仅1977—1979年三年中,我国石油部就进口钻杆9.96万吨,平均每年3.32万吨;而1980年向国外订货达3.84万吨,约占全世界当年生产钻杆总产量约20万吨的16％。我国进口钻杆数量大,对国际市场是一个很大的冲击,特别是在世界能源危机的影响下,国际市场钻杆价格从
Oil and natural gas are important raw fuel for modern agriculture, industry, transportation and defense industries and also one of the necessary fuels for people’s daily life. Focusing on the geological exploration and drilling of oil and gas is an important link in the four modernizations in our country. At present, the drill pipe necessary for drilling in our country, especially the high strength drill pipe required for drilling, deep well are all imported from abroad. In the three years from 1977 to 1979, China’s oil ministry imported 99,600 tons of drill pipe, an average of 32,200 tons per year; while in 1980, it placed orders for foreign orders of 38,400 tons, accounting for about 200,000 of the world’s total annual production of drill pipe Tons of 16%. China imports a large number of drill pipe, the international market is a great impact, especially in the world energy crisis, the international market price of drill pipe from
