Abstract: The deep-well drilling, logging and testing technology and equipment project (Phase Two) is a sub-project of one of the country’s key technological projects – “Large-scale Oil and Gas Fields and Coal-bed Methane Development.” The managerial organs were launched and perfected in execution of the project with the efforts strengthened for evaluation of the proposal and control of the process. Design was made at the top level, aiming at making breakthroughs in key technology. The efforts are focused on indoor experiment and basic theoretical study, combination of research with production, and field experiment in the difficult zones. Based on the technological research in the past few years, a number of landmark results have been achieved, such as PCDS-Ⅰprecise pressure-controlled drilling system. Therefore, the high-end equipment and unique technologies have been created, improving China’s oil drilling technology.

Key words: key technological project, technological research, organization and management, drilling

摘要： 深井钻录、测试技术和配套装备（二期）项目是国家科技重大专项“大型油气田及煤层气开发”的子项目。在项目实施过程中，建立健全管理机构，加强方案论证与过程控制，严细分工，强化协作，实施顶层设计，努力突破核心技术，狠抓室内试验和基础理论研究，推进产学研相结合，积极进行疑难地区现场试验与推广应用。经过几年攻关，取得了一批以PCDS-Ⅰ精细控压钻井系统为代表的标志性成果，打造出高端精良装备和特色技术，提高了中国石油钻井技术水平。
