What should be paid attention to when selecting and installing the jet mud mixer?

As we all know, we need to choose all mechanical equipment that is suitable for our own construction in order to give full play to its ideal working performance. The same is true when we choose a jet mud mixer. Only when the jet mud mixer is correctly selected, calibrated and reasonably installed can it achieve ideal working performance. Next, let's talk about how to choose a jet mud mixer? How to install it?

Selection of jet mud mixer

1. It must meet the requirements of on-site slurry mixing. Generally, the mixing funnel processing capacity must not be less than 150m3/h. For those special wells with large circulation tanks and high power of the pump group, a mixing funnel with a slurry mixing capacity of 300m3/h can also be selected. In order to ensure the need for well pressure, it is recommended that each well team be equipped with a set of spare mixing funnels, and the spare funnels are connected to the system in parallel in most cases.

Once the drilling fluid funnel is determined, the pump, motor, feed pipeline and discharge pipeline must be reasonably designed to have a suitable flow rate under the recommended pressure head. For example, if the displacement of the drilling fluid funnel is strictly required to be 2082l/min under 23m pressure head, the feed and discharge pipeline sizes should be selected according to the equipment instructions. The friction head loss of all pipelines and connections at a flow rate of 2082L/min should be determined, so the 23m pressure head should be added to the funnel; the next step is to select a pump and impeller that can provide 2082L/min at the required total pressure head. When the pump is selected, the model of the motor that adapts to the drilling fluid density can be determined. If the maximum drilling fluid density available is unknown, it is recommended to use 2.4g/cm3 drilling fluid as the calculation basis.

Installation of jet mud mixer

1. Minimize the resistance along the inlet and outlet pipelines, so the pipelines should be short and thick, and the elbows should be smooth. The jet funnel is equipped with a corresponding venturi tube to improve the processing capacity, accelerate solid phase diffusion and prevent agglomeration.

2. The height of drilling fluid lifting: If the discharge is to enter the tank of different decks or a very high tank and funnel, the mixing rate will be reduced. When the height is from 1.83-3.66m, the barite addition rate will decrease by 17%. If the lifting requirement is very high and the pump capacity is insufficient, the mixing capacity will be greatly reduced.

3. Strengthen maintenance. In most cases, the back pressure shall not be greater than 20% of the input pressure.
