Abstract

See full text

A cement mixing method and apparatus for mixing cement used in cementing oil wells casing and the mixer used in that method. The mixer employs a straight bulk cement inlet, five annular recirculation jets and five annular water jet orifices located downstream of the recirculation jets so that all of the jets discharge at an angle towards the mixing chamber and the discharge from the water jet orifices intersects with the flow from the recirculation jets. This five jet, intersecting flow design allows for more thorough wetting of the cement powder with a smaller, lighter, less expensive and more durable mixer that is less inclined to foul and easier to clean.
