mud cleaner

Recently GN shipped high G force drying shaker and mud cleaner for offshore project. The technical configuration is as below:


1) The shale shaker is installed on the catching tank with offshore lifting standard, The lifting pad on the 4 corners of the catching tank is made to meet the offshore lifting standard. GN F version high G force drying shaker with G force up to 8.0G, the 2 nos of Italy Oil vibration motor are equipped with the shale shaker, GN own made explosion proof starter have options of ATEX, IEC EX to meet different client’s requirement. As the first phased cleaning equipment, the performance of the shale shaker is very important, a good performance shale shaker will reduce the drilling waste, recover more useful drilling fluids, reduce the coarse solids effectively from the drilling fluids, and protect the further equipments like centrifugal pump, desander cone, desilter cone, so that they will not be damaged by coarse solids and high solids content, the users can save drilling cost a lot.


2) The mud cleaner is also called 3 in 1, it is the combination of underflow flow shale shaker, desilter cone and desander cone. The desander cone is the second phase cleaning with separation cut point 45 microns, the desilter cone is the third phase cleaning with separation cut point 25 microns.
3) The shaker screens equipped with the shale shaker and mud cleaner is composite material frame shaker screens, the working life is much longer than normal steel frame shaker screens, the storage life is up to 5 years, the effective screen area is 20% larger than traditional steel frame shaker screens.

Recently GN solids control shipped one batch of the shale shaker, decanter centrifuges to Russia drilling rig. The client will produce the mud tank locally to save freight cost, import tax and save delivery time, and buy the major equipments from GN.


Shale shaker is the most important equipments and first phase cleaning equipment for oil drilling rig solids control equipments, the lastest model shale shaker is F version shale shaker. Compared with the previous version shale shaker, the features of F version shale shaker is as below:
1) Composite material frame shaker screen for longer working life, the screen mesh over API 60 all use 3 layers wire mesh for reliable quality.


2) The screen deck bottom is made of stainless steel 304 material for better Corrosion resistant, with 3 layers costing and painting with Japan Kansai brand or US PPG brand Marine anticorrosive painting.
3) Italy Oil brand vibrator or Itavibras or US Martin brand vibrator to meet client’s different explosion proof requirement。

Decanter centrifuge with 3200rpm high speed to separate the low gravity solids, after long period drilling, more and more fine solids will accumulate in the drilling fluids, which can not be separated by desilter cone and low speed decanter centrifuge, then the recovered the drilling fluids can not be reused to prepare for new drilling fluids, the user need the high speed centrifuge to reduce the solids content and separate the fine solids out. Normally they will use the low speed centrifuge before the high speed centrifuge for barite recovery, or they can use a VFD decanter centrifuge to use for both barite recovery and LGS if there is not enough space to install 2 centrifuges.
If you need major shale shaker, mud cleaner, decanter centrifuge for oil drilling rig, pls contact with GN solids control.

Recently GN solids control shipped several units of solids control equipments for Uzbekistan for cold weather, these equipments are special for low temperature operation to -50℃.We have provided such low temperature solids control equipments to Russia area oil & gas drilling rigs before, including the containerized drilling waste management system. The technical configuration of low temperature containerized drilling waste management system is as below:


The feeding system to the drilling waste management system is through screw conveyor, it is transferred to the open top of the vertical cuttings dryer. One unit of vertical cuttings dryer installed on the mud tank, the discharged solids are dropped down to a continuously working screw conveyor to ship it out from the opening of the standard 40ft container. The fluids dropped to the mud tank and the screw pump will transfer it to the VFD decanter centrifuge ,which is also installed on a short mud tank, the fluids are treated by the VFD decanter centrifuge again and the solids discharged will be also transferred out by the screw conveyor for disposal. Another screw pump is installed on the vertical cuttings dryer mud tank as the flushing pump, once the working is finished, it is necessary to flush it or when the screen basket is blocking, it is necessary to flush with the flushing pump.


All the equipments are installed inside the 40ft container to keep the system warm in cold weather below minus zero degree, to prevent it from getting frozen. The 40ft container is with windows and doors for convenient operation, all the walls attached with the Insulation for better warm.
