Geostatistical simulation method and device for structural variation transition probability of aquifer

The invention is suitable for the technical field of hydrogeology, and provides a geostatistical simulation method and device for the structural variation transition probability of an aquifer, and themethod comprises the steps: calculating a vertical discrete Markov chain model of a geological type of a target region according to stratum lithology data; fitting the vertical discrete Markov chainmodel according to a continuous Markov chain to obtain a vertical continuous Markov chain model; calculating a lateral continuous Markov chain model according to the vertical continuous Markov chain model; calculating a three-dimensional Markov chain model according to the vertical continuous Markov chain model and the lateral continuous Markov chain model; according to the three-dimensional Markov chain model, obtaining a geostatistical model of the structural variation transition probability of the aquifer. By means of the geostatistical simulation method for the aquifer structure variationtransition probability, the
