GN Solids Vacuum Pumps for drilling waste cleaning to Africa

Last week we delivered 2 units vacuum pump to African customer for drill cutting transfer. Drill cutting is separated out from drill mud. High solids content and include different size particle . Some the solids of oil base drilling mud is also very high viscosity. The traditional pump is no way to transfer these kind material. GN solids vacuum pump is specially designed for this kind application.

From product name vacuum pump we can know it is different with traditional electrical pump. This pump is driven by high pressure air. The suck power was generated by venture structure . High speed air flow go through the venture, generate differential pressure inside and outside venture, and suck the air out from pump tank, then inside the tank will be a negative pressure space. Which will suck the material into the pump tank. After the tank full sludge, pump will switch to discharge model. High pressure air feed into pump, and then push solids out of pump tank , and finish the discharge.
As usually, the pump need at least 0.8 M pressure , higher pressure higher power. But as usually we control the air source lower than 1.4 Mpa. For different pump,required air flow is vary. Such as our bigger model GNSP-40B, need 17 cube meter air source per hour; for 20B required 8 m3 air supply. This pump is maintenance free. It is almost no spare parts. No wearing parts. But before stopping the machine, make sure the pump discharged all material inside of pump tank. Otherwise, some material will stick on pump after drying and block pump. Solids vacuum pump is not only used in oil gas industry, but also good at transfer dry solids powder, such as sand, and particle smaller than 5mm.
When you select our pump, you need to consider the suck height and discharge height. Also welcome to contact GN to get the suitable model.

How to select the suitable shaker for drilling mud

As we all know shale shaker is the core equipment for solids control equipment on the solids control system. Which used to remove out the big drill cutting and improve the property of drilling mud. How to select the suitable shale shaker is very import for drilling work.

Generally, the well pad must be equipped with at least one shale shaker. The purpose of shale shaker and other solid removal equipment is the same, which is to reduce the drilling cost. Drilling operation usually requires limiting the content and size of solids in drilling fluid. The shale shaker can remove large solids in drilling fluid that returns to the ground. If these solids are retained in the drilling fluid, many drilling problems will be caused. First, it is necessary to decide whether to choose a clay slip conveyor or a clay remover, which must be considered when cobalt meets new rock formations. Secondly, consider whether to use a coarse mesh screen. When a large amount of drilling cuttings or clay returns to the wellhead, it is necessary to use a coarse mesh screen. Generally speaking, when the drilling fluid flow rate exceeds 1000 gal/min when cobalt enters the open hole with a diameter of 172 in, it is required to use a coarse screen before using a fine screen. Finally, the number and type of the main shale shaker used to treat all drilling fluids should be selected. The selection goal is to make the unweighted drilling fluid pass through the most detailed screen cloth as much as possible. For weighted drilling fluid, the use goal of vibrating screen is to make all drilling fluid pass through the API200 mesh screen cloth (too fine screen cloth will remove more weighting agent).

GN solids control can provide different kind shale shaker, and also the other kind solids control equipment, if you have demand on these equipment ,welcome to contact us, we will recommend the suitable model for your project.
