摘要
霍其士—莱赫曼(Hodges—Lehmann)法是用自然伽玛能谱、中子、自然电位、声波、电阻率、密度等测井资料,采用15种参数,并根据各种方法的有利条件和不利因素,有选择地提取和利用6种计算结果,综合估计并确定地层泥质含量。通过大庆油田肇州地区7口井25个储层资料计算,表明该方法具有较好的实用效果。
Fifteen parameters from Natural Gamma Ray Spectroscopy、Neutron、SP、Sonic、Resistivity and Density logs are adopted in Hodges-Lehmann method. With advantage anddisadvantage factors of various logging methods taken into consideration, six computationresults are selected for the evaluation and determination of shale content. Hodges—Lehmannmethod has been used for the computation of 25 reservoirs in seven well in Zhao Zhouregion, Da Qing Oil Field. Results are proved to be good.
