1949年以前的旧中国,工业落后,地质普查和勘探工作量都很小,钻探设备的技术水平很低,根本谈不上钻探设备的研究和制造。虽然中国早在公元前600年已用冲击法钻进盐井深达几百英尺,公元1500年钻井深达2000英尺,被认为是世界钻探的先驱之一,但近百年来我国的科学技术落后了,其中也包括钻探技术和设备。解放前,我国钻探设备在数量上是很少的,而且都是来自国外。在我国最早使用机械进行钻探的公司,有据可查
Before 1949, old China lagged behind in industry, census geology and exploration workload were very small, drilling technology is very low, simply do not mention drilling equipment research and manufacturing. Although China has used impingement methods to drill saltwater wells hundreds of feet long as early as 600 BC and 2,000-deep wells drilled in 1500 AD, it is considered one of the pioneers of drilling in the world, but our country’s science and technology lagged behind in nearly a hundred years , Which also includes drilling technology and equipment. Before liberation, drilling equipment in China is very small in quantity, and all are from abroad. The earliest companies that use mechanical drilling in our country are well documented
