Concept: The drilling mud cleaning cycle is to remove the harmful solid debris, reserve the clean drilling mud to meet the demand of drilling mud spec under the drilling process. Drilling waste management system is a general term of all drilling fluid solids control equipments used in the drilling process.


Function: To prevent the oil-gas well from clogging, breaking, and decrease the drilling torque and friction resistance, reduce the pressure fluctuations of the hollow suction, increase the drilling speed, extend the drilling head life, and reduce wear and tear of the equipments. Methods: The common methods are mixture-thin methods, swap methods, machine methods and additive-chemical methods. Machine method is by using screening, centrifugal separation and gravity separation to separate the solid phase according to the different size and density, therefore, to control the solid phase in the drilling mud.


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

The technical process of complete group of mud cleaning system should meet the specification of five level solid phase control (shale shaker screening, degassing, desanding, desilting, centrifuge) and the provoke of mud. The merger of each solid 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 solid control equipment.


2 Drilling mud cleaning cycle

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

Hi-G dryer shaker screen may be the 1st gear for drilling cuttings management. The operator normally use 1 or two set Hi-G dryer shaker with higher mesh screen to separate the significant particles and use following equipment decanter centrifuge to separate the fine solids, finally get clean drilling mud which can flow back to mud technique or be taken back to liquid mud plant for storage.

GN Solids America with technology mature equipment have occupy huge waste management marketplace. Some buyer obtain GN gear straight for small quantity waste management project; we also have agent like Scomi Oiltools in Iran or EMEC in Egypt, which get big qty of waste management gear for their substantial projects.

GN Solids waste management equipment have been exported over 60 countries and places. The big customer for waste management spread in Argentina, brazil, Iran, Iraq, Kuwait, Oman, Nigeria, Egypt, Tunisia, Libya. The majority of them are from middle east or North Africa or South Amerca. But recently, we acquire PO from Romania, Europe countries. The customer right after much less than one month discussion, they get 4 sets Hi-G dryer and five sets of screw conveyor. They may be professional waste management that have Swaco 518 centrifuge and also other associated gear in their yard.

The Hi-G dryer is prepared for delivery now. We’ll ship it to Iraq, branch office on the Romania corporation. GN Solids America have awarded CE certificate from DNV society. This could also help GN to offer additional gear to European solids control & waste management service compies.

LiaoHe Oilfield, a CNPC organization, which can be the greatest production base for thickened oil and higher pour point oil in China has already procured 5 unit complete mud cleaning system from GN. The newest ZJ50 rig mud cleaning program has been presently operating nicely about the jobsite soon straight away just after our technicist creating the commissioning.


The crucial equipments list for this 6-Tank approach beneath:

1. three units Shale Shaker each and every capacity of 140m3/hr

two. 1 unit Vaccum Degasser GNCQ360 wich eliminate the reduce in gas from the drilling mud to boost the efficiency of transfer pump.

three. Desander and Desilter just about every single for 1

4. 1 unit Higher Speed Decanter Centrifuge GNLW363

5. Agitators to stop the drilling mud sedimentation

6. Centrifugal Pump for transfer mud internal tank and charge to mud pump.

7. This ZJ50 rig mud cleaning system also equiped with poor boy degasser to stop blowout.

Concentrate on higher level domestic marketplace spot place and International marketplace location, GN generally adheres great 1st, Credit priority. By preserving this principle, GN established lengthy term organization relation with principal oilfield in China and at the moment exported to virtually 60 nations. Collectively using the GN new facility beginning production, welcome clientele household and abroad come for going to and company negotiation.

GN Solids America, as an expert manufacturer for drilling mud recycling method, could each style and fabricate the huge footprint mud program for deep oil gas drilling and very compact structure Mud cleaner for horizontal directional drilling and Piling bored drilling.
In the model line of compact mud technique, GN includes a model of capacity 150 GPM with 1 unit double deck mud cleaner, feed pump program and mud mixing program. The double deck mini mud cleaner has two layers shaker screen, the down layer screen is made use of as the main shaker to get rid of the significant size solid. The liquid going via the screen will likely be transferred by a centrifugal feed pump to the desilter cyclone for the second stage solids handle. The solids discharge out in the hydrocyclone nozzle will be dry once more by the upper layer screen of the mini mud cleaner for a lot more recovery from the mud. This mini mud cleaner has total 3 panels screen, 2 down side and 1 for dryer screen. The under shaker is GN smallest model of GNZS752, 3 unit GN four inch desilter cyclone meet the required capacity of 150 GPM.
To be able to ensure the compact structure, this kind mini mud cleaner is supplied with no base seat. Made use of within the mud tank technique, this double dech mini mud cleaner is welded on the tank. You will discover 4 supports is utilized for welding connection.
Apart from this variety double deck mini mud cleaner, GN Solids America could also provide the huge treating capacity double deck shale shaker for much dryer request and limited region working circumstances.
