In order to realize the effective water injection development of oilfield reservoirs, large-scale fracturing technology was introduced. The simulation confirmed that the large-scale fracturing well has the characteristics of high initial production, fast water injection effect, and rapid water cut rise after the effect., the research results show that compared with elastic development, water injection development can solve the problem of rapid formation energy depletion, and at the same time increase the reservoir producing area and displacement time. The final water content of water injection huff and puff is about 25% lower than that of conventional water injection, and advanced water injection can increase the production of conventional elastic development by about 30% in the early stage. It can be seen that these two new development methods are conducive to suppressing water flooding and improving oil recovery.
Key words: Oil field fracturing / water displacement system / ultra-low permeability oil / development system / volume fracturing / newly added reserves
