Abstract:

Through the Ordos basin sample with Triassic Yanchang formation Chang 2 member sedimentary facies research and analysis, the use of deterministic modeling and the theory of stochastic modeling, using PETREL software, the establishment of a three-dimensional visualization of the study area Chang 2 member geological reservoir facies model, the model and geological interpretation in the whole match, a true reflection of the sedimentary characteristics of the study area, the numerical simulation for the latter part of remaining oil and provide a geological basis. Sand distribution model based on a clear understanding of sand microfacies characteristics distribution in the plane and space, the combination of relations, proved in the study area is mainly sand flat on the NE - SW band distribution, the distributary channel facies under control the trend of the sand body, in the same succession of small rivers within the good level, migration is not swinging, with micro-facies stability.Chang2 member channel development , is the favorable oil and gas accumulation zones.
