Application of logging constrained inversion to the 3-D seismic lithological exploration in coalfield

ZHANG Ai-yin~(1,2), LI Xue-wen~(2), DONG Shou-hua~(1)(1.College of Resource and Earth Science, China University of Mining and Technology, Xuzhou 221008, China; 2. Hebei Geophysical Prospecting & Survey Administration, Xingtai 054000, China)  
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.
