Scalping shale Shaker in Oil and Gas Drilling Operations

The scalping shaker plays a vital role in the oil and gas drilling process. It is the primary equipment used to remove large solids and cuttings from the drilling mud before it enters the next stage of the solids control system.

During drilling operations, solid cuttings are generated as the drill bit penetrates the rock formations. These cuttings must be removed from the drilling mud to maintain drilling efficiency and protect downstream equipment. The scalping shaker is specifically designed to achieve this.

The scalping shale Shaker consists of a vibrating screen or a series of shaker screens that are designed to separate the larger solids from the drilling mud. The screens are carefully selected to allow the fluid to pass through while retaining the solids. The vibrating motion of the shaker helps to effectively convey the separated solids off the screens.

The scalping shale Shaker is typically positioned after the flowline from the wellbore and before other separation equipment such as hydrocyclones or decanter centrifuges. By removing the larger solids at this stage, the subsequent separation equipment can operate more efficiently and effectively.

In addition to removing solids, the scalping shale Shaker also helps to maintain the properties of the drilling mud. By removing the larger cuttings, the shaker helps to control the density and rheological characteristics of the mud, ensuring optimal drilling conditions.

The selection of the scalping shale Shaker is based on factors such as the drilling conditions, mud flow rate, desired separation efficiency, and available space on the drilling rig. The shaker must be robust and durable to handle the demanding drilling environment, with features such as corrosion-resistant materials and a reliable vibration mechanism.

Centrifugal sand pump in oil and gas drilling field

Centrifugal pumps play a crucial role in the oil and gas drilling field. They are commonly used for various applications, including:

Mud Circulation: Centrifugal pumps are used to circulate drilling mud during the drilling process. The pumps help to transport the drilling mud from the mud pit to the drilling rig and then through the drill pipe to the drill bit. They maintain the necessary pressure and flow rate to cool the drill bit, remove rock cuttings, and provide lubrication.

Mud Mixing and Conditioning: Centrifugal pumps are utilized to mix and condition drilling mud by adding chemicals, additives, and weighting materials. These pumps ensure proper blending and consistency of the mud, which is essential for maintaining drilling stability and controlling formation pressures.

Drilling Fluid Transfer: Centrifugal pumps are used for transferring various fluids in the drilling field, including water, brine, diesel, and other chemicals. They help in supplying water for drilling operations, transferring fluids between storage tanks, and facilitating the movement of fluids within the drilling rig.

The diameter of the impeller in a centrifugal sand pump has an impact on the flow rate and head.

Flow rate: Generally, an increase in impeller diameter leads to an increase in the flow rate of the sand pump. This is because the increase in impeller diameter results in higher rotational speed, which in turn increases the centrifugal force of the pump. The increased centrifugal force allows more liquid to pass through the pump, thereby increasing the flow rate.

Head: The impeller diameter also affects the head of the sand pump. Typically, an increase in impeller diameter leads to a decrease in the pump’s head. This is because the increase in impeller diameter reduces the rotational speed of the centrifugal pump, resulting in a decrease in centrifugal force. The reduced centrifugal force leads to a decrease in the pump’s head.

It is important to note that the relationship between impeller diameter, flow rate, and head is interconnected and influenced by other factors such as pump design and impeller shape. Therefore, in practical applications, GN Solids Control suggests users to consider multiple parameters to determine the optimal impeller diameter that meets specific flow rate and head requirements. For specific applications, it is recommended to consult with professional engineers or pump manufacturers for more detailed and accurate information.

Decanter Centrifuge, slurry feed pump, and centrifuge VFD control panel

It is best to have the decanter centrifuge and slurry feed pump, along with their control systems, provided by the same manufacturer. The slurry feed pump for the decanter centrifuge must be associated with the centrifuge’s main control cabinet and have interlocking functionality. It should be capable of reducing the slurry feed rate during overload and stopping the operation in case of severe overload.

GN Solids Control manufactures decanter centrifuges of different models and sizes and can provide a complete control system solution for the centrifuge and feed pump. If the customer intends to use their own feed pumps when purchasing the centrifuges, it is important to gather information about the pump’s motor power, whether it is a fixed-speed or variable-speed pump, and the type of control system used for the pump. It is necessary to arrange for communication between the customer’s electrical engineer and our electrical engineer before placing the order to establish the interlocking functionality of the centrifuge and pump control systems. This ensures smooth system operation and avoids equipment damage due to overload or operational issues caused by the lack of interlocking functionality.

Whenever possible, it is recommended that our company controls the slurry pump for the centrifuge through the provided control cabinet, regardless of whether it is a variable-frequency or fixed-speed control. The task order should clearly specify the pump power and whether it requires variable-frequency control or non-variable-frequency start-stop control.

If the decanter centrifuge is used in conjunction with an oily sludge treatment system, we strongly recommend using a variable frequency centrifuge with three VFDs (Variable Frequency Drives). The three VFDs can adjust the main drive, auxiliary drive, and slurry pump of the centrifuge according to the actual needs, to adapt to different processing requirements. Without using a variable frequency centrifuge with three VFDs, the system operation may be limited, resulting in poor treatment efficiency or operational issues.

GN Solids Control manufactures 2-phase decanter centrifuges, 3-phase decanter, as well as other waste treatment equipment for the oil and gas drilling field, non-oil industries, and industrial separation. We also produce waste treatment equipment for the oilfield environmental protection industry. Please feel free to contact us for inquiries and quotations.
