Description
Technical Field
The invention relates to an amplitude interpretation technology in oil and gas reservoir reflection seismic exploration, in particular to a method for analyzing seismic wave frequency-dependent reflection coefficients of a thin reservoir or mutual reservoir model for correcting Biot-jet flow.
Background
In the development of oil gas exploration and development for more than 150 years, the demand of social development on energy is greatly met, and inexhaustible power is provided for the sustainable development of economy and society of various countries in the world. Reflection seismic amplitude interpretation technology (AVO technology and the like) is an important method for reservoir seismic prediction, and the core of the method is to study the change of the reflection coefficient of seismic reflection waves at a reservoir interface along with the incidence angle. The modern oil and gas seismic exploration develops towards reservoir fine description and micro-pore structure research, and a thin (mutual) layer reservoir prediction technology is a difficult technology. The reservoir is a typical pore medium, and the reservoir seismic prediction technical research based on the pore medium wave propagation model is more consistent with the actual medium form and receives more and more attention.
A plurality of evidences indicate that seismic waves have a high frequency dispersion effect in a reservoir, the phase velocity and the attenuation change along with the frequency, and further, the reflection coefficient also has a frequency variation effect. The frequency-dependent reflection coefficient provides more analyzable attributes for reservoir seismic prediction. Therefore, the method for analyzing and researching the frequency-dependent reflection coefficient of the seismic wave of the thin (mutual) reservoir model based on the pore medium wave propagation theory has important scientific research and application value for oil and gas seismic exploration and prediction.
For the reservoir seismic wave reflection coefficient analysis technology, a common method is to use a Zoeppritz equation based on a single-phase medium to analyze the change of the reflection coefficient along with the incident angle. However, the Zoeppritz equation is complex and not practical. In 1961, bortfeld proposed a simplified formula, but the relationship between Bortfeld and lithology was not clear and was not popularized. In 1983, hilterman divides the longitudinal wave reflection coefficient in the Bortfeld formula into a rigid factor and a fluid factor, gives the wave reflection coefficients of longitudinal waves and transverse waves, and has a complex equation. In 1985, shuey simplified the longitudinal wave reflection coefficient in Aki and Richards formulas, and the longitudinal wave reflection coefficient is decomposed into a plurality of units and is easy to apply on a computer. Many oil and gas reservoirs exist in the form of thin (mutual) layers, and the analysis of the seismic reflection coefficient of the thin (mutual) layers is always the difficulty of the prediction of the reflection seismic reservoirs.
Many researchers have developed thin (inter) layer seismic reflections based on Zeoppritz's simplified equations for single phase media (Kallweit et al, 1982, liu et al, 2003, lu et al, 2019). With the increased awareness of reservoirs, hydrocarbon reservoirs are increasingly recognized as typical pore media. The reflection coefficient of seismic waves should develop based on the pore medium theory. 1990. In the years, wanshanghai studied the propagation of elastic waves in two-phase media, and derived the equations for the reflection coefficient and transmission coefficient of elastic waves in two-phase media. In 1992, the reflection and transmission of sound waves at the interface of a two-phase medium were known from a series of studies by Johngxiao et al. In 2006, yong school and so on studied the two-phase medium AVO equation and parameter simplification thereof based on the Biot model, and the practicability of the two-phase medium AVA equation is enhanced through parameter simplification in the process.
In 2015, lihongxing and the like derived AVA equations of wave reflection and transmission at an interface containing a multiphase medium based on an improved BISQ multiphase medium theory. With the development of petrophysics, people realize that the frequency range of seismic waves is also in dispersion in size, and particularly, the dispersion is more obvious when the seismic waves propagate in oil and gas reservoirs. Chapman (2005), guo chile et al (2016) performed frequency-dependent AVO analyses based on a viscoelastic model. As the pore media continues to evolve theoretically, researchers have further realized that fluid flow at the mesoscopic scale is a significant cause of wave attenuation and dispersion. The seismic reflection wave amplitude reservoir prediction based on the pore medium theory can accurately and directly describe the fluid in the oil and gas reservoir.
In summary, the following problems mainly exist in the research of the existing method: the vast majority of reservoir seismic reflection coefficient analysis is based on a simplified Zeoppritz equation of a single-phase medium, and the characteristics of multiphase and pore media of the reservoir are not considered. Meanwhile, the frequency-dependent reflection coefficient analysis is also based on the equivalent medium thought, and the fluid characteristics of the oil and gas reservoir are difficult to accurately describe. Furthermore, no seismic reflection coefficient analysis method studies based on thin (inter) layers of porous media have been found.
