深部地层地质岩芯钻探技术探讨

Exploration on core drilling technology in deep stratigraphic geology

综合介绍了深部地层地质岩心钻探技术在设备的选择与钻井液的性能需求,并阐述了采用科学钻探的重要性,并对科学钻探技术的发展进行了回顾。同时,还结合了现阶段所运用的科学技术,通过对钻头工作层、孔内压力、钻具扶正器的改善,直接实现了延长钻头寿命、改善地层钻孔偏斜以及深孔易断钻杆等问题。以科学技术为例,介绍了国际社会上实施科学钻探的过程中,所带有的独特技术与成就。

The selection of equipment and the performance requirement of drilling fluid in deep stratum geology core drilling technology are introduced. The importance of scientific drilling is introduced, and the development of scientific drilling technology is reviewed. At the same time, combined with the current science and technology, through the improvement of drill working layer, bore pressure and drilling tool centralizer, we directly realized the problems of prolonging the life of drill bit, improving the formation drilling deviation and drilling hole in deep hole. Taking science and technology as an example, this paper introduces the unique technology and achievements in the process of implementing scientific drilling in the international community.
