【摘要】 大斜度井、水平井钻井活动推动了随钻测井技术的发展,在海上钻井中几乎100%使用随钻测井。目前大多数电缆测井项目都可按随钻的方式进行,一些LWD探头的测量质量已经达到同类电缆测井仪器的水平。随钻遥测,随钻电法、声波、核、核磁共振、随钻地震等技术近几年具有长足的发展。随钻测井资料主要应用于地质导向和地层评价。大力发展随钻测井技术是国外油田技术服务公司的一个主要关注方向。我国发展随钻测井技术要有新的思路,实现跨越式发展,才能紧跟世界石油工业先进技术的发展步伐,达到提高国内随钻测井技术水平的目的。更多还原

【Abstract】 Highly deviated and horizontal well drilling activities have been propelling the development of logging-while-drilling technology which is adopted in almost 100% of offshore drilling operations.Nowadays,most wireline well logging jobs can be carried out in while-drilling mode,and some logging-while-drilling(LWD) sensors are good enough to compare favourably with the same kind of wireline logging tool family.While-drilling telemetry,electric,acoustic,nuclear,and while-drilling seismic technologies have significantly progressed in recent years.LWD data are mainly applied to two aspects,namely geosteering and formation evaluation.Major foreign oilfield technology service companies are attaching great importance to the research and development of logging-while-drilling technology.Creative idea and strategy are needed for leaps-and-bounds development of China’s LWD technology.更多还原
