陕北油田是我国发现和开采最早的油田。去年,原油产量达到43万吨,比改革前的1979年翻了两番。与此同时,石油天然气勘探也获得了突破性的进展,近两年,先后在子洲、米脂、榆林等地发现含气构造。经对榆林镇川堡两年多时间的勘探试采,已控制天然气储量35亿m~3。去年底和今年初,又在靖边和子洲打出高产气井,试气日产量 Northern Shaanxi Oilfield is the earliest oil field discovered and mined in China. Last year, crude oil output reached 430,000 tons, more than quadrupled from 1979 before the reform. In the meantime, breakthroughs have also been made in oil and gas exploration. In the past two years, gas-bearing structures have been discovered in Zizhou, Mizhi, Yulin and other places. After more than two years of exploration and mining at Yulin Jinchuan Fort, it has controlled 3.5 billion m3 of natural gas reserves. Late last year and early this year, they also hit high-yield gas wells and trial gas production at Jingbian and Zizhou
