摘要
随钻测井资料主要应用于地质导向和地层评价。随着仪器性能完善和理论研究的深入,研究重点已转移到随钻测井资料解释评价上。在前人工作基础上,指出随钻测井地层评价的难点主要有5个方面:仪器设计、测量方式、环境影响因素、解释模型和参数计算。分析了随钻测井仪器在电阻率测井、声波测井、核测井和核磁共振测井中的地层评价功能。介绍了随钻测井数据处理和定量解释技术的新进展。基于大量的数值模拟,从定性的角度对随钻测井响应分析应当注意的问题作出说明。指出了随钻测井解释评价今后的发展方向。
The dominant application of logging while drillling （LWD） data is geosteering （especially for drilling series） and formation evaluation. Recently, with the great progress in both tool＇s performance and theorical methods, the studied key points are gradually moving to LWD formation evaluation technique. Based on the numerical hard work by the previous researchers, indicated is that the difficulties of LWD formation evaluation technique are the following 5 as- pects., instrument design, measurement pattern, environmental impact, interpretation model and parameter calculation. Analyzed are applications of LWD formation evaluation technique in resis- tivity log, acoustic log, nuclear log and NMR log. Introduced are the new trends in LWD data processing and quantitative interpretation. In view of abundant numerical simulation, illustrated qualitatively are the prominent issues in LWD log response interpretation. Pointed out is the trend of LWD formation evaluation technique, and it should be helpful for other scholars in petrophysical field.
