摘要： A multi-phase down hole injector related to a down hole tool for oilfield well drilling, has a shooting pipe, an axial hole disposed in the center of the shooting pipe, one end of the shooting pipe is connected to an ellipsoid guide, at least two housing seats sets are disposed along the shooting pipe, every housing seat set are disposed with at least two housing seats of radial symmetry, the inner ends of every housing seat is separately connected to the axial hole, every housing seat is disposed with a injection barrel by the base, and the explosive cavity is disposed between the base and the housing seat. The injected viscosity fluid can exert squeezing and shearing force to the rock to make the channel and breach smaller or eliminated.
