摘　　要：南海东部油田陆丰某油气藏属于深层岩性圈闭油气藏,也属于边水油气藏,经过多年的开发,剩余油分布存在不确定性,在调整井水平井钻进过程中存在钻进风险。随钻核磁共振技术能提前预测储层岩性、能准确识别储层流体性质,在南海东部LFX-X-H1井深层水平井地质导向中应用时,成功指导现场随钻过程中的井身轨迹调整,提高了钻井效率,实现了油田增产。The LFX-X oil and gas reservoir in the eastern oilfield of the South China Sea belongs to the deep lithologic trap oil and gas reservoir,also belongs to the edge water oil and gas reservoir.After years of development,the distribution of remaining oil is uncertain,and there are drilling risks in the process of horizontal drilling of adjustment wells.Nuclear magnetic resonance while drilling technology can predict reservoir lithology in advance and accurately identify reservoir fluid properties.When applied in geological steering of deep horizontal well LFX-X-H1 in the eastern South China Sea,it successfully guides the adjustment of well trajectory while drilling,improves drilling efficiency and achieves oilfield production increase.
