Abstract:Wide-band restrictive inversion and lithology restrictive inversion may be used to produce seismic data controlled inversion section, from which rock density attenuation coefficient and reservoir CDT(product of the coefficient and the thickness of Carboniferous system)are derived easily. Reservoir CDT values reflect reservoir quality. Lithologic trap may be then discovered by analysing CDT distribution and geologic structure. This technique has been applied to Mingyuexia tectonic belt to map out three kinds of Carboniferous reservoir areas,in which five lithologic traps are delineated obviously. Analysis says that the reservoir is better in its north than in its south.
