Study On Three Dimensional Stratigraphic Structure Simulation Based On Finite Borehole

Because of the geological tectonic movement and sedimentation,natural strata present more complex distribution.The traditional stratum profile can't express the complex stratum structure,and can't meet the basic requirements of modern large-scale geotechnical engineering.With the development of modern engineering,more and more detailed information about engineering stratum conditions is required,so the technology of three-dimensional stratum modeling emerges as the times require.Three-dimensional stratum stochastic simulation can describe complex stratum structure more intuitively and reflect more real stratum spatial distribution by using three-dimensional simulation map.With the development of stratigraphic theory and the improvement of world computer counting level,three-dimensional stratigraphic modeling technology has emerged.At the same time,the application and development of computer technology in reservoir engineering,geotechnical engineering and hydraulic engineering also promote the progress of three-dimensional formation modeling technology.Because of the geological tectonic movement and sedimentation,natural strata present more complex distribution.The traditional stratum profile can't express the complex stratum structure,and can't meet the basic requirements of modern large-scale geotechnical engineering.With the development of modern engineering,more and more detailed information about engineering stratum conditions is required,so the technology of three-dimensional stratum modeling emerges as the times require.Three-dimensional stratum stochastic simulation can describe complex stratum structure more intuitively and reflect more real stratum spatial distribution by using three-dimensional simulation map.With the development of stratigraphic theory and the improvement of world computer counting level,three-dimensional stratigraphic modeling technology has emerged.At the same time,the application and development of computer technology in reservoir engineering,geotechnical engineering and hydraulic engineering also promote the progress of three-dimensional formation modeling technology.Based on the borehole data obtained from the model groove test,the scientificalness,correctness and applicability of the application of the three-dimensional Markov chain model in the three-dimensional stratum structure simulation are verified,and the influence of the number of boreholes on the stable simulation results is analyzed.Based on the drilling data of practical engineering,the influence of drilling layout on the simulation results of three-dimensional Markov chain is studied.The number of drilling holes and the location of drilling holes will have a great impact on the simulation results.
