现代钻井技术发展趋势

旋转钻井的发展可分为初期阶段、发展阶段、科学化钻井3个阶段。科学化钻井后期阶段成果主要有3大项：实现了井下信息实时检测、传输、处理、分析；开发了井下导向和井下闭环钻井系统；发展了新钻井技术。现代钻井技术发展趋势是：向信息化、智能化方向发展；向多学科紧密结合、提高油井产量和油田采收率方向发展；向有效开采特殊油气藏方向发展。建议：能引进的采取引进-消化-创新的技术路线来跟踪前沿，不能引进的国内自主开发；在水平井钻井技术、多分支钻井技术和欠平衡压力钻井技术三大新钻井技术方面，我国目前还有许多基础工作要做，建议有计划地组织攻关；钻井科研工作者在观念上应有新的转变。目前石油工程技术的发展要求钻井工程不仅要建油流通道，而且要担负提高单井产量和油田采收率部分任务以及开发开采特殊油气藏的任务，因此钻井科技人员应熟悉和了解采油工程和油藏工程有关理论和技术。参9

Development trend of the modern drilling technology

Rotary drilling has experienced 3 periods of development: elementary, development and scientific drilling period. There are 3 great achievements in the late period of scientific drilling: the realization of downhole real time signal record, transmission, treat and analysis; the development of downhole directional drilling and downhole closed loop drilling system and the development of new drilling techniques. The modern drilling technology is developing toward informatization and intelligentization, combination of multi-disciplines to improve oil production and enhance oil recovery, and effectively development of special oil & gas reservoirs. If the technology can be imported, the method of introduction-digesting-innovation should be applied to keep step with the advanced technology on drilling. If it cannot be imported, develop it by ourselves. Much basic research works should be performed on the 3 new drilling techniques as horizontal drilling techniques, multilateral drilling techniques and under balance drilling techniques. At present the development of petroleum engineering requires that the drilling engineering should not only construct the channel for the production of oil but also take the task to improve the production of single well, enhance the recovery and explore the special oil/gas reservoirs. So the drilling technicians should be familiar with the theory and techniques related to the oil reservoir engineering.
