1 新疆石油局根据地矿局叶城玉力群浅钻中轻质原油信息3年头口探井发现柯克亚高产油气田 椐《新疆通志》第九卷地质矿产志的大事记载,1974年12月,地质局二大队在塔里木盆地西南缘皮山—叶城普查自然硫,在玉力群构造上浅孔中采到油砂样品,经石油局分析确定为轻质原油。1975年3月28日石油局致函地质局,赞扬二大队对玉力群液态原油的发现,对国民经济和国防建设都有极其重要的意义;同年4月燃化部石油勘探开发组致函地质局,感谢提供玉力群普查钻孔的含油显示资料,为玉力群构造和叶城凹陷开展油气普查勘探提供了重要线索。据王秋明(1992)回忆,1975年石油局地质调查配合电测深,查明了该构造深部有隆起,1976年2月勘定柯参1号井,5月开钻至1977年5月17日钻至3783.1m新第三系中新统地层,地下高压岩石颗粒间饱和凝析油滴,在短时间内,突然释放发生特大油气井喷,井底高压油气流呼啸冲向天空,其声震耳欲聋,大地为之颤抖,原油跌落地面,防护不严,引起
1 Xinjiang Bureau of Geology and Mineral Resources Yecheng Group according to the group of light drilling in the light crude oil information 3 years head exploration wells found Kekeya high-yielding oil and gas fields, “Xinjiang Annals” Volume IX geology and mineral resources record events, December 1974, The Second Brigade of the Bureau of Geology collected natural oil samples from the Pishan-Yecheng, southwestern margin of the Tarim Basin, and collected oil sands samples from shallow holes in the Yulizun Structure. On March 28, 1975, the Petroleum Bureau sent a letter to the Bureau of Geology, applauding the discovery by the Second Brigade of the liquid crude oil of the Yu Liqun group, which is of great significance to the national economy and national defense construction. In April of the same year, the Petroleum Exploration and Development Group of the Ministry of Fuel Oil wrote a letter Geological Bureau, thanks to provide Yu Liqun census drilling oil-bearing data for the Yulizun structure and Yecheng sag provides an important clues to oil and gas exploration survey. According to Wang Qiu-ming (1992) recalled, in 1975 the Bureau of Petroleum geological survey with electrical sounding, it is ascertained that there is a deep uplift in the structure. In February 1976, it was assigned to the well of Ko Sen No. 1 and drilling started in May to May 17, 1977 Drilling to 3783.1m Neogene Miocene strata, underground high pressure rock particles between saturated condensate oil droplets in a short period of time, the sudden release of extra-large oil and gas well blowout, bottomhole high-pressure oil and gas flow roared toward the sky, the sound deafening, Trembling earth, crude oil dropped to the ground, lax protection, causing
