Logging evaluation and petrophysical modeling
2021-03-17Logging evaluation and petrophysical modeling is one of the important contents of seismic petrophysics research, and the seismic petrophysical model established on the basis of a variety of data, which can effectively describe the quantitative relationship between the microscopic physical characteristics of the reservoir and the macroelastic properties. It provides a reliable basis for the quantitative interpretation and fluid identification of the reservoir.

Petrophysical reservoir parameter inversion
2021-03-05The reservoir parameter inversion based on the petrophysical model overcomes the problem that the traditional method of interpreting the results of elastic inversion has only statistical concepts and lacks physical significance. It also innovatively combines the seismic petrophysical model with the reservoir parameter inversion to realize the direct inversion of reservoir parameters based on the petrophysical model, and realize the quantitative inversion from elastic parameters to reservoir parameters.

Reservoir prediction technology based on wide-bandwidth azimuth seismic data
2021-03-05Wide bandwidth, wide azimuth and high-density seismic data are important development directions for seismic exploration in recent years. The seismic data not only realize the collection of three-dimensional seismic data with small distance, number of avenues and high density, but also realize the transformation from narrow azimuth to wide azimuth. In recent years, with the development of technology, the acquisition, processing and interpretation of three-dimensional seismic data based on broadband, wide azimuth and high density have become an important development direction of exploration.
