摘要
鄂尔多斯盆地油气勘探历史漫长,新中国成立之前,盆地内只开展了少量的油气勘探工作,大量系统的石油地质调查和勘探开始于新中国成立之后。在1955—1968年的14年间,虽然积累了大量地质资料和寻找油气的经验教训,但既未发现工业油气流,也没有提出可以肯定能发现油气的地区或目标。自1969年起,遵照李四光"打回老家去"的指示精神,石油普查工作从渭河与河套外围地堑转回鄂尔多斯大盆地,先后在庆阳、华池、吴旗地区发现了6个侏罗系油田,在延安—吴旗以北发现了5个亿吨级大油田,在盆地中部发现了奥陶系陕北大气田。鄂尔多斯盆地油气发现历史表明,油气的发现来自于地质学家的观念,应重视以地质锤和放大镜起家的基础地质工作,地质调查方法应用及勘查程序上必须有针对性,既不能把复杂问题简单化,也不能将特殊问题一般对待,应按照实际情况确定选区方针,发现问题并解决问题。
The history of oil and gas exploration in Ordos Basin is long.Before the founding of new China,few of oil and gas surveying has been done in the basin.A lot of systematic petroleum geological survey and exploration began after the founding of new China.During the 14 years from 1955 to 1968,a large number of geological data have been accumulated,but neither commercial petroleum has been found,nor definite prospects or targets have been determined.Since 1969,according to the instruction of ＂return to Ordos Basin＂,the petroleum exploration came back to Ordos Basin from Weihe and Hetao Graben.Six Jurassic oil fields in Qingyang,Huachi and Wuqi,five large oil fields over hundred-million tons in northern Yanan-Wuqi,and a large Ordovician gas field in centre of the basin had discovered successively.History of petroleum exploration in Ordos Basin showed that oil and gas discovery comes from geologist＇s idea.We should attach great importance to basic geologic survey.Application of geologic surveying methods and exploration procedure must have pertinence.Neither can simplify the complicated issues,nor can generally approach the special problems.The exploration areas must be determined according to the actual situation.
