| description | The invention discloses a blending device for high-pressure foams and mud. The device comprises a first blending chamber and a second blending chamber which are connected into a whole and are in communication; the divergent ends of the first blending chamber and the second blending chamber are respectively provided with a mud inlet and a blended-body outlet; the interior of the cavity of the first blending chamber is sleeved with a mud spray pipe, and the inclined side wall of the first blending chamber is provided with a foam pipe; and the foam pipe, the mud spray pipe and the first blending chamber are in fixed connection and are integrated into a whole. With the blending device provided by the invention, the high-pressure foams can be smoothly added according to a proportion and uniformly mixed into drilling mud, so specific gravity of the mud is effectively reduced; pressure of the mud on a drilling working face is decreased; occurrences of accidents like well collapse are prevented; and success rate of well drilling is guaranteed. |
