The Application of Geostatistics Inversion in Reservoir Prediction
Journal Title: Scholars Bulletin - Year 2016, Vol 2, Issue 3
Abstract
Abstract: A region of delta distributary plain distributary channel sand body development change fast, strong heterogeneity, small thickness of single sand body, sand body distribution, conventional deterministic inversion due to earthquake frequency limit, in the form of seismic inversion low vertical resolution, often it is difficult to identify. Geostatistical inversion method based on stochastic modeling technology, can effectively integrated geology, logging and 3 d seismic data, greatly improve the prediction results of vertical resolution, can more precisely describe reservoir slight change, can better identification of thin sand body. Using geostatistical inversion method for the thin layer of sand body is forecasted, through high resolution of geostatistics inversion of wave impedance and density inversion profiles can effectively identify the thin layer of sand body lateral distribution on the inversion profile. Keywords: Geostatistical inversion；Stochastic simulation；Thin sand body identification；Reservoir prediction.
