当前，勘探工作是我国陆上石油工业的重中之重。根据全国第二次油气资源评价，在深部地层有丰富的油气资源尚未探明，故今后深井和超深井的钻井工作量会有较大幅度的增加。因此，打好打快深探井和超深探井是陆上钻井工作者面临的光荣而又艰巨的任务。文中介绍了陆上石油深井钻井的基本情况，说明新区的深探井、超深探井钻井工作还不适应陆上石油工业当前发展的要求；分析了深探井钻井存在的工艺技术难点，对解决难点的对策进行了探讨，并提出了建议。
At present, exploration is the top priority of China’s onshore oil industry. According to the second evaluation of oil and gas resources in the country, abundant oil and gas resources in the deep strata have not yet been proven. Therefore, the drilling workload of deep and ultra-deep wells will increase greatly in the future. Therefore, playing a quick drilling exploration and ultra-deep exploration wells is a glorious and arduous task facing onshore drilling workers. This paper introduces the basic situation of deep well drilling in onshore oilfields. It shows that deep well exploration wells and ultra deep well exploration drilling work in new area are not suitable for the current development of onshore oil industry. The difficulties in the process of deep well drilling are analyzed. Countermeasures were discussed, and made recommendations.
