Abstract
A mobile cement batch mixing plant includes at least one slurry tank, a cement storage tank, at least one slurry pump and at least one clean pump supported on a transportable frame. The slurry tanks and cement storage tank are connected by a plumbing system. The flow of water and cement slurry between the tanks and within the plumbing system is controlled by a series of valves and pump controls. A cement slurry is formed by adding water and cement to the slurry tank through a fluid vortex within the slurry tank. The cement slurry can be pumped out of the slurry tank into a well.
Claims13
A method for mixing a cement slurry with a mobile cement batch mixing plant, the method comprising the steps of:
- pumping water to a cylindrical slurry tank that includes a cylindrical upper portion, a conical lower portion, and a closed top that together define a slurry tank interior;
- recirculating the water from the conical lower portion, through a recirculation pump, and into the cylindrical upper portion through a tangential nozzle in the cylindrical upper portion to induce a vortex within the slurry tank interior;
- adding a continuous stream of a powdered cement from the closed top into the vortex within the slurry tank interior to create a cement slurry;
- recirculating the cement slurry from the conical lower portion, through a recirculation pump, and into the cylindrical upper portion, wherein the vortex is maintained within the slurry tank while the powdered cement is being added and the cement slurry is recirculating;
- and
- measuring a density of the recirculating cement slurry while the powdered cement is being added until a desired density of the cement slurry is reached.
