The multi-point geostatistics algorithm becomes a truly practical stochastic modeling algorithm. The traditional two-point geostatistics stochastic modeling method can only consider the correlation between two points in space, while multi-point geostatistics focuses on expressing the correlation between multiple points, which overcomes the shortage of two-point geostatistics and is the current international frontier research direction. Multi-point geostatistics is relative to the traditional two-point geostatistics, which can reflect the geometry and mutual coordination relationship of multiple points in space, and has a greater advantage in modeling the distribution of complex-shaped geological bodies.
