Method and device for drawing attribute contour map

The invention provides a method and device for drawing an attribute contour map. The attribute contour map meshing method comprises the steps that a weight coefficient function including weight coefficient factors is selected; a Monte-Carlo random sampling method is used for solving the weight coefficient factors of the weight coefficient function; the obtained weight coefficient factors are substituted into the weight coefficient function to obtain weight coefficients; the multiplicative average values of known discrete point values and the weight coefficients are used as the values of points to be fixed; the values of all the points to be fixed are figured out, and the attribute contour map is drawn. According to the method and device for drawing the attribute contour map, the anisotropism of a reservoir is taken into account, and thus the distribution condition of reservoir physical property parameters such as porosity and permeability of an underground reservoir can be reflected more accurately.
