The studies of plane heterogeneity are as follows : the text counts the parameters of the sandlayers " geometric shape of different sedimentous microfacies ; speculates the conditions of lateral communication by sandstone density according to the method brought forward by j. r. l. allen ; gets a group of parameters including the reservoir thickness, porosity and coefficient of permeability by using kriging method according to the data of logging results ; makes certain the direction of coefficient of permeability with variation function by modeling globosity function ; divides the sandlayers into five types by using the method of flowing cell based on three parameters, that is x h, kxh and h / h, and accounts the favorable region. on the base of above - mentioned studies, the text evaluates the heterogeneity of sandlayers and gives the resolutions to these problems to serve the development of the field
