| Cementing Pumping Units Specifications
(with Automatic Density Control) |
Twin cement pumper, with dual diesel engines Allison transmissions and triplex pumps. Pumpers are equipped with 41/2 fluid ends and state of the art Automatic Density Control mixing system. Its basic operating principle is as follows:
The cement flow rate is controlled and adjusted via automatically controlled valve by the computer. The slurry densitometer detects the actual density and feeds the measured value back to the computer. A water flow meter mounted on the mixing system measures the water flow rate and sends the measured value to the computer. With the water rate and the desired density, slurry design and measured density, the computer calculates the required cement value position. A command signal is sent to the hydraulic actuating system to adjust the opening of the bulk cement-metering valve and thus controls the slurry density to the set range. The system displays and records the slurry density, discharge rate, total volume, pressure and bulk deliverability. |

| 100 BBL Batch Mixer and Continuous Cement Mixing Skid |
100 bbl batch and continuous mixing skid which is the latest in mixing technology and density control. It includes two 50 bbl batch tanks with agitators and a 8 bbl mixing tank allows batch mixing of cement for primary, plug and squeeze cementing operations, flush and spacer mixing operations.
The 50 bbl batch tank also provides averaging of slurry density, and additive concentration. The system makes the operators’ job easier by making the process more forgiving to potential job problems such as unsteady bulk delivery. Thus the quality of the resulting slurry adds significant value to the customer. |
