Abstract: This paper introduces four kinds of block incomplete factorization OrthoMin acceleration methods, that is, the first, the second, the third orders of block incomplete factorization for natural order, and the first order for D4. These methods have been used in horizontal well reservoir simulation and have obtained good results.
