Baoleng structure in Bayindulan depression is one of the three major areas abundant in oil sand resource in the Erlian Basin.The oil sand in the study area is featured by large thickness,shallow depth,high oil content which is a subtle oil sand and was formed because of the paleo-reservoir destruction.In order to figure out the distribution and resource extent of the oil sand,electrical prospecting method has been adopted in Baoleng structure.After that,the corresponding relationship between electrical parameters and oil sand distribution is established,the area of oil sand was determined and finally the geological oil sand resource is forecasted.The favorable area determined by electrical prospecting was tested by drilling and the result indicated the electrical prospecting is an effective method.
