旧中国的凿井事业极其薄弱，凿井技术十分落后，我国商人经营的小型凿井企业绝大多数仍沿用着相当原始的人力“竹弓子”打井设备和操作方法，只有少数用机械凿井。解放后，党和政府十分重视凿井事业的发展。1949年清华大学农田水利专修科，首次开设了凿井工程课，培养了第一批凿井技术人员。当年，农业部机械灌溉工程处组织力量修复了从原河北省建设厅凿井队接收的九部钻机，投入了国民经济建设。当时使用的主要有四种类型钻机：一是日制铁方塔回转式钻机，钻深300米；二是日制木方塔冲击式钻机，钻深150米；三是美制拖挂车装冲击式钻机，钻深100米；
In old China, the cause of sinking was extremely weak and the sinking technology was very backward. The vast majority of the small-scale sink companies run by Chinese merchants still followed quite primitive man-made “bamboo bow” drilling equipment and operation methods, and only a few were using mechanical sinking . After the liberation, the party and government attached great importance to the development of the cause of shaft sinking. In 1949 Tsinghua University farmland water conservancy specialized subject, for the first time opened a sinking engineering classes, cultivating the first batch of drilling technicians. That year, the Ministry of Agriculture Machinery Irrigation Agency organized and repaired the nine rigs received from the former Hebei Provincial Construction Department drilling crew and put into national economic construction. At that time, there were mainly four types of drilling rigs used at the time: the first one was the Japanese-made iron tower rotary drilling rig with a drilling depth of 300 meters; the second one was a Japanese wooden square tower impact drilling machine with a drilling depth of 150 meters; the third was an American- Drilling rig, drill deep 100 meters;
