【摘要】 中国石油天然气股份有限公司重点风险探井牛东1井获高产工业油气流,这是继1976年任丘潜山发现后,渤海湾盆地冀中坳陷潜山勘探的重大突破。牛东1井深潜山油气藏勘探历时33年,经历了6个勘探阶段,华北几代勘探家持之以恒,持续进行先进物探技术和方法攻关,不断建立和完善潜山地质结构,最终在二次三维地震资料采集及叠前深度偏移处理后完全落实潜山形态,标定牛东1井。落实潜山圈闭的同时,深化研究、创新认识,综合评价潜山成藏条件,降低深潜山勘探的风险。牛东1井的成功,发现了渤海湾盆地乃至中国东部目前最深的高产油气藏,打开了冀中坳陷深潜山勘探的新局面,对于推动渤海湾盆地深层勘探具有里程碑意义。更多还原

【Abstract】 Oil and gas with high flow rate is produced at Niudong1 well,and this is PetroChina’s another great breakthrough in exploration of buried hill in Jizhong Depression of the Bohai Bay Basin,after the discovery of Renqiu buried hill in 1976.Exploration for oil and gas in deeply buried hill of Niudong1 well took 33 years and experienced six exploration stages.Several generations of explorationists kept on striving to make technological breakthrough in geophysical exploration,continuously built and improved geological structure of buried hill,finally confirmed buried hill morphology after processing of the second 3D seismic data acquisition and prestack depth migration,and calibrated Niudong1 well.The deepest high-yield oil and gas reservoir in the Bohai Bay Basin and even East China was discovered then,opening up new dimension in exploration of deeply buried hill in Jizhong Depression.This is of milestone significance to promoting deep exploration of the Bohai Bay Basin.更多还原
