Stochastic Simulation Methods And Application To Reservoir Simulation

Geologic statistics appeared in the 1960s, In those forty years, variogram, kriging technique and stochastic simulation technique has become the whole theory system. Stochastic simulation technique has an advantage because it analysis and token space distribution of geologic phenomena, therefore, Stochastic simulation technique has applyed to petroleum engineering, water geologic engineering .The theme of thesis is stochastic simulation methods and application to reservoir simulation. The content of research is the item of "carbonate rock reservoir's forecast and identity" from the item "development of oil and gas in 2004 of reservoir description of crevice and cave carbonate rock of Tahe oil and gas field". The chief object of the study is to found a 3D geological-model which could explain geological reservoir character of Ordovician system's carbonate rock under Tahe oil and gas field, furthermore, we will supply basic information for next development study.Nowadays, simulation technique in oil and gas field is about moclastics , there is not good effect on carbonate rock reservoir. The thesis is based on geological research, and giving grid-designing and data analysis, simulation methods: for big hole, using GMPP; for crevice and cave, using SIS; for reservoir parameters, using SGS and could-transform. Last , the thesis give modeling using Strom, and this modeling is examined and analyzed.
