Description: 吸收系数是进行储层描述和油气预测时的一个重要参数 ,它对岩性变化具有很高的灵敏性。结合层位解释结果从地震资料中提取该层位地层吸收系数的空间分布对于提高油藏描述及油气预测精度具有重要作用 ,并可与其它地震、测井和地质信息相结合直接用于圈定油气分布范围 ,估算储量-Absorption coefficient is an important parameter in the reservoir description and hydrocarbon prediction. It is very sensitive to the variation of lithology. The spatial distribution of formation absorption coefficients which are estimated from horizon interpretation of seismic data plays an important role in improving accuracy of reservoir description and hydrocarbon prediction , and can be used to delineate hydrocarbon distribution and estimate reserves when combines withother seismic data , log, and geologic data.

Description: 粘弹性地震波的衰减不仅与传播时间有关，而且与子波的频率、速度场的分布、射线路经、地下构造展布都有关，因此，仅仅利用反Q滤波对粘弹性的吸收和频散做一维补偿不能完全的恢复地震波长的本来特征。-Viscoelastic seismic wave attenuation is not only associated with the propagation time, and and wavelet frequency distribution of the velocity field, the ray path, subsurface structures spread are related, using only inverse Q filtering viscoelastic absorption and dispersion do The one-dimensional compensation can not completely restore the original features of the seismic wavelength.

Description: CHARACTERISTICS OF AN EARTHQUAKE by gterra1970
seismic event recorded by 100 fixed stations in the territory.
known the epicenter obtained from the arrival times to the stations
we seek the power of the earthquake and the average absorption of the ground
The data are modeled exponentially Pr = Pt*exp^(-2*alpha*x)
where Pr is the power received in the station,
Pt power in the epicenter, alpha the attenuation, x the station-epicenter distance in Km Platform: |
