In order to acquire data necessary to increasing penetrating speed in deep formation, the Daqing oilfield tested non-reservoir formations beneath section Quantou-2 in Well Xushen-21 with air drilling.

大庆油田为给提高深层地层机械钻速提供科学依据，在徐深21井的泉头组2段以下非储层段进行了空气钻井试验。

As a result, we found that the problerm can be solved by The Combined Drilling Technology, which also can enhance the wellbore quality and reduce the cost of drilling.

利用复合钻井恰恰可以达到防斜快打，保证井身质量，提高庆深气田泉头组到登娄库组地层机械钻速，节约钻井成本的目的。

The atmosphere is intellectual, rugged and ascetic, and the college is a democratic body, where student-led committees decide admissions, hire the faculty and mind most matters of policy.

学校的校训是学术、劳动、自制。深泉十分民主，学生领导的委员会有权决定招生，教职工应聘和学校政策的制定。
