The Effect Analysis of Map Smoothing Method on Sedimentary Facies Model

Smoothing on the sedimentary model with SIS method based on MAPS can make the realization more close to geological acknowledge, what is more, reproducing space distribution and characterization of sedimentary facies model more accurately. In this paper, taking fluvial reservoir as an example, selecting the sand body volumes connected to wells and number of independent sand bodies as experiment target. 6 trials are designed to determine main factors and levels. At first, Fluvism algorithm is a better method to achieve a simulation of river sand body that have been choosed. Then condition information which is used for SIS simulation can be obtained with appropriate well space. At last, Petrel model software is used to simulate and calculate various testing programs. According to the variety of the experiment target during the experiment process, effect on sedimentary facies model controlled by smoothing process can be analysed and evaluated.
