Abstract

The invention proposes a thin reservoir stratum seismic forward modeling simulation method based on the bivariant geologic modeling technology, and the method comprises the steps: (1), setting the basic size of a main model; (2), dividing a target layer region and a non-target layer region on the main model; (3), designing a target layer model and a non-target layer model with the features of a thin reservoir stratum (2m or less) under different proportions; (4), discretizing a model through employing the variable sampling technology, and obtaining the discrete data of the model; (5), carrying out the forward modeling simulation based on the obtained discrete data through employing a forward modeling algorithm, and generating a synthesized seismic record. The method is advantageous in that the method can achieve the construction of the thin reservoir stratum (2m or less), can carry out the seismic forward modeling simulation of the thin reservoir stratum (2m or less), and enables the achievement of seismic simulation to be used for solving an actual problem that the recognition of the thin reservoir stratum is difficult better.

Description

technical field [0001] The invention relates to the field of seismic modeling, in particular to a thin reservoir seismic forward modeling method based on double-variable geological modeling technology. Background technique [0002] Seismic exploration technology is the most widely used geophysical method in oil and gas exploration. It uses the changes in the velocity, amplitude, frequency, phase, waveform and other parameters of seismic waves propagating in different media to analyze and predict the distribution range of oil and gas reservoirs. layer properties. With the deepening of exploration and development, seismic exploration has gradually developed from the structural exploration of understanding the underground structure form to the lithology exploration of directly using seismic information to judge lithology, analyze lithofacies, and quantitatively calculate the physical parameters of rock formations. Reservoirs in these complex depositional environments are usual...
