///Taking the South-Two area for an example, under the guidance of the theory of reservoir architectural structure and sedimentology, comprehensively making use of the cores, logs and performance, adopting the hierarchy analysis, pattern guidance and performance verification methods, the authors have performed some quantitative research on the parameters of composite channel sandbodies, single point bar sandbodies and the lateral accretion bodies in point bars in South Two area, built a 3-D model of point bars. With the changes of seepage field and gravity, the effect of lateral accretion layer on remaining oil has been analyzed. Study shows that the point bar sandbodies in PⅠ2a unit are meandering point bar sandbodies formed by the lateral accretion of distributary channels in coastal delta distributary plain. The space combination model of lateral accretion bodies is horizontal-obique type. The width of lateral accretion bodies is 38.5～54.0 ms, the average dip of lateral accretion layer is 9.5°, and separation of lateral accretion layer is about 15 m.
