ABSTRACT

In Xingnan development area, the secondary and tertiary infill well mainly exploit the thin and low permeable layers, which have many characteristics, such as the layer is too much, the development is poor and thin, the layer has the small interlayer thickness, the variation range of the lithology, physical property and oil content is large, the nonuniformity is more serious. Although applying the limited entry fracturing when the wells put into production , some oil and water wells which corresponding sand body has not establish effective displacement relationship, this will lead to low producing proportion of thin and poor reservoir. To overcome the problem mentioned above, by breaking through the existing fracturing design principle, reasonably optimizing the corresponding fracturing layer, fine dividing section, personalized design of operation scale, controlling the influence factors of fracturing effect and so on, finally we establish a new reconstruction model which the single sand body apply corresponding fine control fracturing. The field test obtain a better result, it has proved the applicability of the technology.
