随钻测井是一种能够既钻开地层又能同时对地层信息进行实时测量的钻井技术。近年来水平井钻井、大斜度井活动使得随钻测井技术得到了发展,尤其是在海上钻井中随钻测井这种技术的利用率几乎是100%。随钻遥测,随钻电法、核、声波、随钻地震以及核磁共振等技术在最近几年有着较大的发展空间和较好的发展前景。随钻测井主要应用于地层评价以及地质导向。我国在随钻测井这种技术的研究领域上,只有突破创新才能够跟上世界石油工业技术的前进步伐。本文将系统的对随钻测井这种技术近些年的发展以及将来的趋势进行介绍。
Logging While Drilling is a type of drilling technology that enables both real-time measurement of formation information and both formations. In recent years, horizontal well drilling and high-deviated well drilling have led to the development of LWD technology. In particular, the utilization rate of LWD technology in offshore drilling is almost 100%. Drilling telemetry, MWD technology, nuclear, acoustic waves, while-drilling seismic and nuclear magnetic resonance technology in recent years have a larger space for development and better prospects for development. Logging while drilling is mainly used for formation evaluation and geosteering. In the research field of logging-while-drilling technology in our country, only by breaking through innovation can we keep up with the progress of the world’s oil industry technology. This paper introduces the development of the technology of LWD in recent years and the future trend.
