超深井钻井技术研究及工业化应用

Ultra Deep Well Drilling Technology Research and Industrial Application

随着我国油气使用量的逐渐增多,对于油气的开采也朝着超深领域发展。而在超深井的钻井过程中存在着复杂多变的特殊的地质特性如压力系统、地层岩性、储层流体以及工程力学等。我国的钻井工程面临着没有优化创新的设计,施工过程中风险大,钻井速度相对来说比较慢,没有办法对工程质量等技术方面的难题进行控制。在钻井施工过程中表现出钻井工期长、故障多、投资多、无法达到钻井目的层的现象。主要介绍了超深井钻井技术,分析超深钻井要点、难点,探讨解决的措施。

With the gradual increase in the use of oil and gas in China,the development of oil and gas is also moving toward ultradeep areas.However,there are complicated geological characteristics such as pressure system,formation lithology,reservoir fluids,and engineering mechanics during the drilling of ultra-deep wells.Drilling engineering in China is facing a design without optimization and innovation.The risk during the construction process is large,and the drilling speed is relatively slow.There is no way to control technical problems such as engineering quality.In the process of drilling construction,there are phenomena of long drilling period,many failures,high investment,and failure to reach the target layer of drilling.It mainly introduces ultra-deep well drilling technology,analyzes the key points and difficulties of ultra-deep well drilling,and discusses measures for solution.
