GN Oilfield Drilling waste Cutting dryer

When we mentioned cutting dryer, there are always 2 explanations. One is for High H dryer (Hi-G dryer), or even named as high H shale shaker or cutting drying shale shaker. Its normally used for water structured mud drilling cuttings. It is just a special designed shale shaker with high G force or older to 7. 5 or maybe 8. And the G pressure is adjustable to suit for further applications. High G cutting dryer is with a longer screen deck and screen region, mostly 4-panel.
Another kind of cutting dryer is vertical cuttings dryer (short name while VG dryer). Vertical Cutting Dryer uses centrifugal drive to dry drilled solids through OBM or SBM. A stainless-steel screen bowl traps “wet” solids and make them improve to 900RPM with Gary the gadget guy force to 420G. It may also offer super high speed 1200RPM with G force in order to 750G. Liquid is obligated through the screen bowl open positions, while “dry” solids usually are extracted by the angled routes attached to the cone, which often rotate slightly slower compared to bowl. Tungsten carbide floor welding protects the routes from abrasive and makes sure long operational life. The objective of this is maintaining a constant hole between the scroll and screen bowl, which is very important intended for proper operation.


In some cases, when folks only mentioned cuttings dryer or cutting dryer, is actually means High G dryer shale shaker. And Top to bottom dryer is for vertical cuttings dryer.

1 The technical process of the mud  cleaning system and the combination of the fluid cleaning equipment.

The technical process of complete group of drilling fluid cleaning system should meet the specification of five level solid phase control (screening, degassing, desanding, desilting, centrifuge) and the provoke the drilling fluid. The merger of each solids control equipment is very important, the through out of one to five level of mud cleaning equipment should each corresponding, and the spacing of the proper distance were is appropriate.  To have certain overlap during the cleaning process, make the smaller particles of the processing incomplete in the up one had been disposed in the next solids control equipment.

2 Drilling fluid cleaning cycles

The mud back from the opening of well through the pipeline and conveyed the drilling fluid to the shale shaker. The first phase of cleaning completed by shale shaker, then entered the mud tank, the drilling fluid flowed from the mud tank through the tank slot into the desander and desilter (if detect the exits of gas, vacuum degasser will process to remove the gas) the fluid after processing of the centrifugal steps and through the tank slot enters the inhalation cabin.  The cleaned fluid then will reuse for lubricate and cooling the drill bit.

GNZJ594E-2S12N Mud Cleaner  is the 4 panels screen installed, low buffer box in placed and pair with two Martins 2.5 HP motor.  The control box is met IEC EX, ATEX AND UL explosion proof and certified.  GNZJ594E-2S12N mud cleaner is combination of desander, desilter and shale shaker in one.  The design contains two 10 inches hydrocyclones for desander and twelve 4 inches hydrocyclones for desilter.  It combine 4 panels shale shaker to become mud cleaner has 240 m3/h treating capacity.  The use of the hydrocyclone for the weighted mud is prohibitively expensive (due to loss of barite) and since ultra-fine screens are incapable of handling the entire mud stream, the other kind  of solids removal device is necessary. A unit consisting of both of these devices covers their individual limitations. It is the drilling mud cleaner.  The main function of drilling mud cleaner is eliminate the solid particles whose particle sizes are larger than the barite, and collect the barite in drilling fluid. When the weighted drilling fluid pass the hydrocyclone, a large number of barites in underflow pass the screen, the barites will be returned to cycle tank
