摘　　要：针对钻井技术发展对地层评价技术的要求,提出了钻井地层评价的研究内容和核心问题,指出了其理论基础和主要技术手段,给出了提高测井资料地层评价精度的途径,并讨论了在地应力、井壁稳定、地层抗钻特性评价和出砂预测等几方面的研究进展,提出了钻井地层评价的发展趋势。According to the demands of drilling technology for formation evaluation, this paper presents the contents and the key tasks for researching drilling formation evaluation, and its rationale and main technical measures. Approaches to improve the formation evaluation accuracy by the logging data are also introduced in this paper. Meanwhile, the new progress in in-situ stress, wellbore stability, formation drilling strength, and sand prediction were discussed. Finally, this paper puts forward the development tendency for drilling formation evaluation.
