Fig. 6. Optimization diagram of the optimum-size and distribution of fracturing. (a) Size and distribution are not optimized vertically. Large quantities of fracturing fluid and proppant enter the non-reservoir. (b) The fracture network distribution along the wellbore and between wells is not optimized. There are a large number of unstimulated areas when the interwell interference occurs. (c) Vertical size and distribution are optimized. The reservoir has been fully stimulated. (d) Through the optimization of size and distribution, the uniform transformation along the wellbore and the full transformation between wells are realized.
