As the drilling operation going on, more and more solids will come into the mud, lead to the arising of mud weight. The change of mud weight is not good for drilling operation. Decanter centrifuge is required to remove the solids, and control the mud weight.

GN industry centrifuges

GN Solids Control is China leading brand for oil drilling mud decanter centrifuge. We have different model centrifuge for option, including:

9 inch bowl baby centrifuge, this is popular for mining/ waste water treatment.

14inch bowl high speed centrifuge, this model centrifuge is equivalent to SWACO 518 centrifuge / Derrick DE1000 centrifuge. Fixed speed centrifuge and variable speed is available per the client’s request

18inch bowl big volume centrifuge, this model centrifuge has two options: GNLW452 and GNLW453. The two option centrifuge is used differently. GNLW452 is very popular for HDD drilling, or for barite recovery; GNLW453 variable speed can be used for fast drilling

22inch bowl big capacity centrifuge, this is only GNLW553-VFD centrifuge for tunneling or other field fast drilling.

30inch bowl centrifuge is designed for industry application.

For oil drilling application mud weight control, we recommend fixed speed GNLW363CG 14inch bowl centrifuge for better option.

  • Firstly, fixed speed centrifuge is much easier for operation than variable speed centrifuge.
  • Secondly, we can offer 2700RPM bowl speed centrifuge, 3200RPM pulley with belt as backup.
  • Lastly, the fixed speed centrifuge is much better price than variable speed centrifuge.

Centrifuge feed pump, we recommend screw pump, positive displacement pump. The pump motor is controlled by the centrifuge control panel.

Telescopic skid is for option. The client can compare the price from GN, and local fabrication price.

Except for centrifuge, vertical cuttings dryer is another popular item for oil drilling waste management. The client needs it to recover the valuable oil based mud and return it back for drilling operation. We have two options: GNCD930 series cuttings dryer and GNCD730 series cuttings dryer. The client can choose the proper model per request.

GN designed GNCD930 vertical cutting dryer is already finished and tested in the field. Its specs is similar with CSI cutting dryer WSM-04. Its rotary speed is 890rpm, and processing rate is 30~50tons per hour( actual data). Max bowl diameter is 930mm.

Daily inspections should be made at start-up until a permanent maintenance schedule can be set up. Once a schedule has been established, only routine inspections and general observations will be necessary.

Cutting Dryer Maintenance

1 Basket:

Basket is not wear part, unless its damage caused unbalance, you do not have to replace it before that.

2 Filter-screen:

it is important to always maintain flite to screen clearance,it is critical to the proper machine performance.

3 It is very important to inspect the condition of the rotor at every screen change. This is necessary as the rotor is the connecting member between the external drive shaft and the basket, and is one of the members which is subjected to normal abrasive wear by the product.

4 LUBRICATION

Except for the motor bearings, which are grease lubricated, all bearings are oil lubricated. A direct driven gear pump, mounted along the outer base, circulates oil through the gear unit and overflows to the outer external shaft bearings.

The oil should be changed every 1600 hours of operation or every three months, whichever occurs first. To change oil, drain oil from the gear unit and drain pot.

Together with Vacuum Collection System, Screw conveyor is also applied for collection of drilling cuttings? What is their difference in function?

Screw conveyor is the main equipment to collect drill cuttings from solids control equipments, in actual application, vacuum unit is used to transfer the cuttings from one screw conveyor to another, then the 2ndscrew conveyor transfer the cuttings to cutting dryer. Otherwise the position ofshould be higher than the inlet of cutting dryer, or the position of cutting dryer should be very low, it is not convenient to locate them in site.

The M-I SWACO vacuum collection system consists of Cuttings Collection Boxes, a Rig Vacuum Tank, a vacuum rotary hopper and a Vacuum Power Skid. It has the advantages of being a totally contained system powerful enough to transport both fluids and cuttings vertically as well as horizontally over fairly long distances. Modular and adaptable, the system minimizes the amount of floor space required for operation. Further, once on-line, the system does not interrupt the drilling operation.

The Drill cuttings Management solution is designed to help maximize compliance with the waste management hierarchy principles, as well as ensuring that local regulations and standards are complied with. Ultimately, disposal will be required in all cases, be it solids and / or liquids.

drill cutting management solution

drill cutting management solution

Drill cuttings management solution usually including but not limit to:

1 collection of drill cuttings

There are various ways to collect the drill cuttings from the solids control system( shale shaker, mud cleaner, decanter centrifuge). Firstly you need a cuttings blowing pump to blow the drill cuttings and waste produced by centrifuge from a collection place in the site to a drill waste storage tank or directly to a transferred truck or boat, they called it ”bulk tank”. Then Screw conveyors are used to transport drill cuttings and centrifuge waste from one location on the rig to another, probably to a vertical cutting dryer in the drilling waste management system.

2 Storage of drill cuttings

A Drilling Waste Container is to storage drill cutting, centrifuge waste and pit cleaning wastes generated during drilling operations. The drilling waste containers are typically transported to a treatment and disposal site for further processing.

After the drilling waste is treated by vertical cutting dryer, the cuttings will be collected by a small waste container and be transported to other place, the fluids are pumped to high speed decanter centrifuge for further process.
