Abstract: In this paper, the author tried to apply the principle and the method of underground stress obtained by hydrofracture construction curve to the development of Daqing oil field.The author researched the variation of underground stress in the oil field developed by water injection.The work has some practical significance in reducing the damage of casing, diminishing fault activity, defining the reasonable demarcation for keeping layer pressure and determining the type of hydro-fracture crack.
