摘　　要：水平井钻井技术作为提高单井产量的有效手段之一在全世界得到了越来越广泛的应用。为了提高水平井的油层钻遇率,就必须在了解钻井区域地层产状和储层发育情况的基础上,优化钻井轨迹,并在钻井实施的过程中,根据情况的变化尤其是随钻测井资料的变化进行及时的调整。研究和应用水平井钻井的测井地质导向技术是确保水平井钻探成功的一项十分重要的技术。本文在多口水平井实际钻探经验的基础上,分析了水平井钻进过程中,随钻电测曲线因岩性变化而相互关系的变化规律,总结了水平井随钻跟踪分析的方法,并通过实例,说明了水平井随钻跟踪分析方法的应用效果,具有很强的实践性。As one of the effective method of improving single well production,the technique of horizontal drilling has been used more and more widely throughout the world.Meanwhile the inclination of the stratum and the distribution of reservoirs are of great importance in the drilling of horizontal wells.To improve the rate of sand-drilled,the well track should be adjusted timely in drilling according to LWD curves and other data available.Studying and using the LWD curve in the course of Geo-steering is of great importance to ensure the success of drilling a horizontal well.On the basis of several horizontal wells,the paper analyzes how the relationships of LWD curves change with the bit＇s different positions in sand-and-shale layers,summarizes the method of LWD according to the LWD curve and makes appropriate decisions.
