Linear motion shale shaker deck angle adjustment

Linear motion shale shaker sometimes are required to treat the drilling fluids uphill or downhill, they all have an easy screen deck angle adjustment function to optimize mud throughput and cuttings conveying speed. The upward angle of the shaker deck prevents the overflow of mud caused by the influx of mud from the wellhead manifold. When the shaker deck angle is greater than 3º, it will be a problem for solids discharge. The mud throughput increases with the upward slope and the delivery decreases. For solid material conveying, solids discharge is slower than liquid fall due to viscous resistance and pressure differential on cuttings load. If the shaker deck angle is too high, even during operation, a large amount of solids will accumulate on the screen surface, causing the screen to block, resulting in drilling fluids overflow. Shaker Vibration and increased residence time of the mud results in better treatment, drier solids discharge, and cleaner treated liquid, which can be used to prepare new drilling fluids and reused by the drilling rig.

GN solids control produce linear motion shale shaker with different screen panels with different treating capacity, by using proper screen deck angle, and different screen mesh, the user can control the shale shaker separation performance according to their requirement. GNZS703F shale shaker deck angle adjustment range is -1°~+5°. We have 2 panel shale shaker GNZS752F, 3 panel shale shaker GNZS703F, 4 panel shale shaker GNZS594F, all of them are single deck linear motion shale shaker, also we have GNZS706F double deck shale shaker, we can produce customized dual motion shale shaker, including linear motion and elliptical motion. The shaker installed 4 sides pre-tensioned composite material frame shaker screens from API 20 to API 325 for option.
If you need linear motion shale shaker, pls contact with GN solids sales.

Drilling waste treatment system manufacturer in China

Right now we have one set of oil based drilling waste treatment system in stock in China, which is brand new and produced in 2021.10. If you need one set of drilling waste treatment system and prefer stock items, pls contact with GN solids control. The system including one unit of vertical cuttings dryer, one unit of VFD decanter centrifuge, one set of vertical cuttings dryer flushing pump, one set of decanter centrifuge feeding pump, one set of fluids collection tank and all the equipments will be installed on the tank skid for convenient transportation. The whole system with explosion proof electric control system and control panel.

To control the drilling waste, there are “4R” to be pay attention to, such as Reduce, Reuse, Recycle, Recover. Obviously, Ruduce is to reduce the drilling waste by using better performance solids control equipments, such as shale shaker, desander, desilter ( mud cleaner), the better of the solids control equipments working, the less drilling waste will be generated, so the further treatment, disposal cost will be reduced a lot.
Reuse is to reuse the drilling fluids which are treated by solids control equipments, which will reduce the generated waste and reduce the treatment cost.

Recycle is to use the drilling waste treatment system (oil based) to recycle more useful oil based drilling fluids, and prepare for new drilling fluids. The vertical cuttings dryer can reduce the oil content on the cuttings below to 5% if the drilling cuttings is fresh and come from primary shale shaker. The fluids will flow to fluids catching tank and the decanter centrifuge feeding pump will feed the fluids to decanter centrifuge to separate the fine solids from drilling fluids, the discharged drilling fluids from decanter centrifuge can be recycled and reused to prepare for new drilling fluids.
Recover is the last step, to get the recovered hydrocarbon, it is not suitable to reuse the drilling fluids, it can be collected as fuel oil.
