摘　　要：鄂尔多斯盆地镇泾油田低孔低渗透储层的开发难度大,地层情况复杂。在钻孔提速提效、高质量高效率的开发过程中,出现了螺纹井眼的问题,对测井资料的评价产生了一定的影响。从螺纹井眼出现的原因入手,分析了其成因及螺纹井眼影响下的测井曲线特征,研究了包络线校正算法,经过测井曲线实例验证,取得了良好的校正效果。The development of low-porosity and low-permeability reservoirs in the Zhenjing Oilfield in the Ordos Basin is difficult and the formation conditions are complex.In the process of improving drilling speed and efficiency,with high quality and high efficiency,threaded borehole problems appeared,which had a certain impact on the evaluation of logging data.Starting from the reasons for the appearance of threaded boreholes,the genesis and the characteristics of logging curves under the influence of threaded boreholes are analyzed,and the envelope correction algorithm is studied.After the logging curve examples are verified,a good correction effect has been achieved.
