本世纪六十到七十年代,在加拿大和美国的落矶山冲断带发现许多大油气田后,引起了地质工作者的广泛兴趣。苏联近年在前喀尔巴阡冲断带也发现了许多油气田。在意大利和德国的阿尔卑斯冲断带也有所发现。我国准噶尔盆地西北缘的克-乌冲断带自1979年以来也发现了大量断裂掩覆油藏,引起了国内外的关注。在冲断带找油,已列为我国第二次石油普查的新领域之一。
After the discovery of many large oil and gas fields in the Rocky Mountain thrust belt of Canada and the United States in the 1960s and 1970s, widespread interest has been drawn from geologists. In recent years, the Soviet Union also discovered many oil and gas fields in the former Carpathian thrust belt. Alpine thrust belts in Italy and Germany have also been discovered. Since 1979, a large number of fault-cleaved reservoirs have been discovered in the Ke-Wu-Shen fault belt in the northwestern margin of the Junggar Basin in our country, arousing domestic and foreign concerns. In the thrust belt to find oil, has been listed as China’s second oil census one of the new areas.
