摘　　要：　利用地震技术解决岩性问题在煤田勘探中一直是近年来人们研究的一个热门课题,与其他地震反演技术相比,测井约束反演技术不仅可提高原始地震资料的垂向分辨率,而且将地震波转换为层的信息,因此正在岩性勘探中得到广泛应用.本文介绍了测井约束反演技术的原理及影响因素,并以开滦集团荆各庄矿某采区岩性勘探为例,说明了测井约束反演技术在煤田三维地震岩性勘探中的具体方法和应用效果.Using seismic exploration technique to solve lithological problems in coal fields is a hot subject in which people have been studing recent years. Compared with the other seismic inversion techniques, logging constrained inversion technique not only can increase vertical resolution of seismic data, but also can change seismic wave data into information of layers, so it is widely used in lithological exploration. In this paper,the principle and influence factors of logging constrained inversion are introduced, and takes a seismic exploration project'using in Jinggezhuang coal mine for example, the methods and application effects of logging constrained inversion technique on the 3-D seismic lithological exploration in coalfields are illuminated.
