回顾了石油钻井技术50年来的发展,着重对近20年发展起来的随钻井下测量与评价技术,井下钻井动态数据实时采集、处理与应用技术,闭环钻井技术,水平井钻井技术,大位移井钻井技术,多分支井及重入井钻井技术等给予了介绍,分析了其技术优势和潜力。明确指出了钻井技术今后的发展趋势是以有利于发现新油气藏和提高油气采收率为目标,向信息化、智能化、自动化方向发展。

The progress of oil and gas drilling technology during the last 50 years,especially during the last 20 years,is briefly rewiewed in this paper.The typical technologies are introduced,such as Measurement While Drilling,Logging While Drilling,Integrated Drilling Evaluation and Logging,Dynamic Data System,Closedloop Drilling Technology,Horizontal Well Drilling Technology,Extended-reach Well Drilling Technology and Multilateral Well Drilling Technology.Their advantages and potentials are then analyzed.All above shows the developing tendency of drilling technology towards information,intelligence and automation in favor of new oil gas reservoir exploitation and oil and gas recovery enhancement.
