摘　　要：针对JH-1井须家河组地层硬度大、取心机械钻速低、岩心质量要求高等问题,采用铝合金内筒中长筒取心技术,同时通过优选取心钻头、优化钻具组合等技术措施,成功解决了取心过程中出现的各种问题,取得了较好的取心效果。介绍了岩心吊装、Gamma扫描、标注等岩心地面处理工艺。该井的取心实践与认识对今后该地区的取心作业具有一定的参考价值。According to the problems of hard formation, low coring penetration rate, and high core quality required in Xujiahe zone of Well JH-1, by using long-barreled aluminum inner tube coring technique and optimizing some technical measures such as coring bit and BHA, the problems are successfully resolved during the coring process, and good coring effect is obtained. The paper also introduces some core treatments on surface such as core lifting, Gamma scanning, and labeling. The coring practice and understand of the well has reference value to coring operations in this area.
