Drilling Waste Management Equipment

Now with the higher and higher environment requirement, the drilling waste cuttings can not be discharged on the drilling site. So we designed and manufactured a set of drilling waste management system. There are two solutions. 

One is using the High G Dry Shale shaker to separate the bigger solids, then using a mud storage and add PAM, then using the Filter Press. The solids is pressed like mud cake, and water discharged is almost clear.

Another is using the Vertical cutting dryer with Screw Conveyors. This is the most common using in the drilling waste management.

Mud Mixing Hopper in Solids Control System

Mud Mixing Hopper

In order to guarantee the performance of drilling fluid, the bentonite, weighting agent and other materials for drilling fluid should be added. The mixing hopper is designed for adding this.

The mixing hopper has two types, one is jet type and the other is centrifugal type. But the most common using is jet type. So this hopper is also called Jet Mud Mixer.

Structure: The jet mud mixing hopper is composed of feeding hopper, butterfly valves, jet pipe, mixing chamber and liquid guide pipe.

Working principle. The mixed liquid with a certain pressure and flow rate is injected through the nozzle of the jet pipe an enters into the guide pipe through the mixing cabin. Now the hopper is venturi type.

Centrifugal Pump Application in Solids Control

Centrifugal pump's application

The SB series centrifugal pumps adopt axial suction structure. The flow parts are anti-wear cast iron. In solids control system, the centrifugal pump transfer the drilling fluid, and feeding for Desander, Desilter and Mixing hopper. The main factors are spare parts can easy find and replace, long working life and low cost.

Common using type parameters.
1). Inlet pipe diameter: 200mm
2). Discharge dameter: 150mm
3). Impeller diameter: 315mm
4). Flow rate: 67 l/s
5). Head: 35 m
6). Speed: 1480 rpm
7). Motor power: Ex-prool type, 45 or 55KW
8). Working life: ≥ 2500 hours

The structure of centrifugal pump

Like the upper photo shows, the centrifugal pump's main parts are pump case, pump data base, impeller, shaft, mechanical seal, coupling, motors and data base etc. The centrifugal pump's seal is mechanical seal, thus make sure there is no leak of pumps. The impeller type is half open type, this lower the flow of pump itself.

Vacuum Degasser in Solids Control

Vacuum Degasser

Vacuum degasser is a special equipment used to treat the drilling fluid. Its very important effect is restoring the drilling fluid's density, stabilizing the viscosity of drilling fluid, reducing the drilling well cost. When the drilling fluid do not contain the gas, the function of vacuum degasser is a bigger power mud agitator.

The type of vacuum degasser is Vertical type.

Horizontal Decanter Centrifuge's Working Principle

Horizontal Decanter Centrifuge's Working Principle

1). The Separation principle

The separation of liquid and solids is finished in the drum bowl. The high speed drum bowl take the inner drilling fluid rotate in a high speed.  Then the drilling fluid was thrown of to the drum wall and form a fluid ring.  The solid phase in the fluid ring are subjected to centrifugal forces hundreds or even thousands of times greater than their own gravity. The solids particles break the resistance of  fluid viscosity and to the inner wall form a solid layer, and the liquid form a fluid layer.  The ratio of the centrifugal force to the gravity of the solid particles in the fluid ring is called the separation factor of the Decanter Centrifuge. The bigger separation factors, the thinner of  separation particles.  In the oil drilling, the decanter centrifuge can be divided i three types.

a).  Lower speed centrifuge. This type decanter centrifuge is also called barite recycle centrifuge. Its separator factor is 500-700. For the lower density solids phase,  its separation size is 6-10 micron meters. For the higher density solids phase, its separation size is 4-7 micron meters.

b). Middle speed centrifuge. This type decanter centrifuge is 800, it can separate 5-7 micron meters' solids. This type is the most using one, using in removing the harmful solids, control mud density and viscosity.

c). High speed centrifuge. This type's centrifuge's separation factor is 1200-2100, the separation size is 2-5 micron meters, and also using in removing the harmful solids. control the mud density and viscosity. It is commonly used in series with low-speed centrifuge to form a two-engine system.  In this system, the lower speed decanter centrifuge is the first phase, the separation barite is sent back to the mud tank to recover the barite.  The liquid discharged by lower speed centrifuge is into a buffer tank. Then using a pump to suction this fluid to feeding in high speed decanter centrifuge. After the high speed decanter centrifuge, the solids is discharged to outside of tank, and the liquid into the recycling system. Using two equipment, both can remove the harmful solids, also escape the waste of barite.

The high speed centrifuge also has VFD type. The frequency can be adjusted.

Decanter Centrifuge is Solids Control Industry

Decanter Centrifuge's usage in solids control industry

Since the lats 1980s, Decanter centrifuge has been widely used in the national oil industry(especially in deep wells and horizontal wells ). It is the dispensable solids control equipment. Decanter centrifuge includes spiral subsidence type, sieve water type, hydraulic turbine type and so on. In the oil and gas drilling industry, the most commonly used is Horizontal spiral sedimentation type centrifuges. And this horizontal decanter centrifuge also has low speed, middle speed and high speed.

Decanter Centrifuge's Structure: Main motor, Back drive motor,Hydraulic couplings, Drum bowl, Differential mechanism and Feeding pump etc.

The main motor drives the roller by driving the pulley on the roller through the belt wheel on the hydraulic coupling. The drum bowl is supported on two bearings. In the drum bowl, there is a screw propeller, the screw propeller is supported on the middle of shaft of drum bowl.  The differential is installed on the bigger side of drum bowl, it is a planetary gear reduction mechanism structure. The output shaft of the differential connects with the propeller and then make the propeller spiral. The input shaft at the right end of the differential is equipped with a pulley, which is driven by the auxiliary pulley to provide the differential input speed.  

The Decanter Centrifuge's Drum bowl is installed in a stainless steel box. The stainless box has two cabins, the left cabin collects the discharged fluid of centrifuge, and the right cabin collect the discharged solids from centrifuges.
