The mud cleaner is used after shale shaker, the desander cone separation cut point is 45 microns, the desilter cone cut point is 25 microns. Over 80% of the solids bigger than 25 microns will be separated out. If much finer solids still need to separate, decanter centrifuge can be used.
Decanter Centrifuge: GNLW553-VFD, the separation cut point is 2~5 microns. The centrifuge bowl diameter is 22 inch, the bowl length is 71 inch (1800mm), the max G force is 2719G and the max speed is 3000rpm. The max gearbox torque is 12000 N.M. and gearbox ratio is 35:1. The differential speed is 0~45 rpm. And designed treating capacity is 500gpm. The decanter centrifuge is drived by VFD control panel, with world famous brand inverter of main motor, back drive motor and pump motor.
The shale shaker, mud cleaner, decanter centrifuge are installed on the customized dimension mud tank, the discharged fluids dropped into the mud tank, the feeding pump ( centrifugal pump) transfer the treated fluids to desander cone and desilter cone, the clean fluids are transferred to decanter centrifuge by screw pump.

Pitless Drilling Waste Management Equipments for International Oilfield Service Company

BY gnadmin 15 May 2020 Uncategorized

Recently GN solids control shipped one batch of pitless drilling waste management equipments for International oilfield service company, including high G drying shaker package, sludge vacuum pump, cuttings dryer.

The vacuum pump is 100% air operated pump to transfer drilling waste from waste pit to vertical cuttings dryer ( for OBM & SOBM drilling waste) and high G drying shaker modular ( for WBM drilling waste). No need electricity power, it is suitable for hazardous area application. The suction horizontal distance is up to 50m, discharge distance is up to 500 ~1000m. The max solids size to be transferred is up to 50 ~ 75mm based on different model, and the max solids content is up to 80%. There are 2 operation mode for option, automatically and manually working, the user can choose different operation mode for easy operation. The compact design structure is for easily installation and movement.

The high G drying shaker is normally used for water based mud drilling waste treatment project, the max G force is up to 8.0G so that the discharged solids will be much drier for easy disposal. The clean fluids drop down into the mud tank, the centrifuge feeding pump can transfer the clean fluids to decanter centrifuge for further treatment.

The vertical cuttings dryer is widely used to treat the oil based mud drilling waste management project, we have 2 models of vertical G dryer for option, GNCD930E with treating capacity 40 tons/ hour, which is the best sold model for standard drilling waste management system. The discharged solids with oil content on the cuttings is below 5%, it can be landfilled or disposal directly once it can meet the environmental protection regulations in the client’s country. The discharged fluids flow to a buffer tank, the clean fluids can be transferred by centrifuge feeding pump to decanter centrifuge for further treatment.

Dual Motion Shale Shaker for interntional drilling company

BY gnadmin 3 May 2020 Uncategorized

As one of the most professional shale shaker manufacturer in China, GN solids control can produce not only linear motion shale shaker, but also dual motion shale shaker, recently one batch of dual motion shale shaker are shipped for international drilling company.
The dual motion shale shaker can work under both linear motion and Progressive elliptical motion according to different drilling depth and drilling fluids requirement. The vibration motor can be adjusted on the starter.

The features for linear motion shale shaker:
Higher G force, higher screen conductance, higher treating capacity, direct action on the drilling cuttings, bigger throw vibration angle, the cuttings stay time on the shaker screen is shorter, it is suitable for the drilling fluids with low viscosity, high fluids flow, high solids content, coarse and hard drilling cuttings, especially it is widely used for first spud, second spud of the oil drilling rig.
The features of Progressive elliptical motion shale shaker:

Slow action on drill cuttings, the cuttings stay time on the shaker screen is longer, the screen opening is not easy blocked, the drilling cuttings not easily crushed. It is suitable for the drilling fluids with high viscosity, low flow rate, high solids content, and easily crushed drilling cuttings. Especially it is widely used for third spud, fourth spud of the oil drilling rig.
Whichever the vibration motion is used, the operator can choose it according to different drilling fluids. The shale shaker with 4 panel shaker screen of composite material frame, as one of the most shaker screens manufacturer in China, most of GN produced shaker screen is with composite material frame, we can produce screen mesh size from API 20 to API 300 as per your requirement, and we have stock for the best sold model replacement shaker screens, for urgent requirement, the delivery can be much faster.
