旧中国,石油工业极其薄弱,建国前夕,全国只有两个地质调查队,几十个地质勘探人员和8台破烂不堪的钻机,90%以上的国土面积没进行过石油地质调查。从1878年在台湾钻成第一口油井算起,到1948年的70年间,仅勘探开发了台湾、延长、独山子、四川、玉门等几个小型油气田,总共生产原油67.71万t。 In old China, the oil industry was extremely weak. On the eve of the founding of New China, there were only two geological survey teams, dozens of geological prospectors and 8 dilapidated rigs in the country. Over 90% of the country’s land area was not surveyed by petroleum geology. From the first oil well drilled in Taiwan in 1878, to 70 years in 1948, only a few small oil and gas fields such as Taiwan, Yanchang, Dushanzi, Sichuan and Yumen were explored and exploited, producing a total of 667,100 tons of crude oil.
