The quantitative analysis of point-bar’s inner-architecture is essentially computation of lateral mudstone’s attitude and lateral accretion body’s scale. Based on recognition criteria of lateral mudstone on log map, three computing methods are used to quantitatively describe the attitude and the scale. Based on the data of attitude and scale, the architecture elements of point-bar can be quantitatively described. On the analysis of relationship between lateral mudstone and remaining oil, then the enrich zone of remaining oil is forecasted and the corresponding development plan will be carried out.
