    Abstract： With continuous development of high water content and low permeability oilfields, reservoir fracturing construction becomes more and more difficult and requirements for fracturing technologies becomes increasingly strict. In order to decrease construction difficulties and number of required segmentation tools and increase reformation efficiency of each unit well section, it is necessary to apply temporary blocking technology for stimulating the subterranean formation. This technology is designed to fracture more than two fissures in the same interval or make the fissures divert, that is, pumping the diverting agents into the subterranean formation to be stimulated and utilizing permeability differences within the formation to change flow direction of treatment fluid so as to produce new fissures. Application of this technology can increase single well yield and reduce the fracturing costs effectively.
