The importance of Drilling fluid and Drilling Fluids Recycle Unit

At present, there are some solids control units to process drilling fluids including : shale shakers, mud cleaners, Desander, desilter, vacuum degasser, mud gas separator(poor boy degasser), slurry mixers, Jet Mixing devices, electronic ignition device, mud gun, centrifugal pump(sand pump), shear pump, decanter centrifuge. While being widely used in drilling industry, slurry dewatering and no dig industry.

Drilling solids control equipment and systems will process and recovery drilling fluids which comes from down hole. Solid control system and units are mainly separate drilling cuttings, recovery barite and effective separation of the solid particles. The treated fluids can be reused in order to reducing the cost of drilling and are environmentally friendly.

Drilling Role:

(1) Clean the bottom, carrying debris and keep the bottom clean, avoid drill bit damage, reduce wear and improve efficiency.

(2) Balance down hole pressure. Prevent blowout and leaking issues. Prevent underground fluid contaminate the Drilling Waste Management.

(3) Cooling and lubricating the drill bit and drill string. Reduce drill temperature, reducing drill wear cost and improve the life of the drill.

(4) balance the side wall of rock pressure in the wellbore to form a cake, a closed and stable wall. Prevention of pollution and reservoir wall collapsed.

(5) Effective transfer hydraulic power. Passing the required down hole drill motor power and hydraulic power drill.

(6) Suspended cuttings and keep weight of fluid. Reduce cuttings settling velocity and avoid damaging the drilling bit

(7) Due to fluids levitation force working on the drill pipe and casing. It can reduce overload when starting up the system.

 In summary, drilling solids control equipment is process the blood of the entire system, if the solid or particles contain of drilling fluids is too high, it may cause a blowout, or sticking fluid is not conducive to drilling speed and cost. After GN Solids control system process, the drilling fluids viscosity and weight will be stable in order to fast drilling speed and reduce the cost.

Solids Control Liquid Mud Plant (LMP)

In the Oil and Gas drilling field, for treating and dealing with drilling mud, there is not only solids control systems and waste management systems. But also, the liquid mud plants, which is also called as LMP. Besides the solids control system and waste management systems, GN Solids Control also have complete LMP or according equipments available.


What is LMP?

LMP is short for Liquid Mud Plant, which is mainly used beside a solids control system or other mud systems for storage the drilling mud. In order to avoid mud from settling, most important equipments used in LMP are mud agitators and mud guns. At a certain distance, usually every 3 meters, there is a mud agitator and beside each agitator, there is a mud gun. And also jet mud mixing equipments, like centrifugal pumps and mud mixing hoppers, used for adding and mixing the chemicals to the drilling mud and keep a desired mud proportion.

Who Use LMPs?

Anyone who use drilling mud in their projects or for their customers, may use LMPs. Those companies include but not limited to:

  1. Drilling companies those who provide their customers drilling service with their own rigs and solids control systems.
  2. Drilling Mud/Liquid companies, who do not participate directly in drilling works, but they provide drilling mud to the users and reclaim the mud back and save it for next use.

GN Solids Control also provide LMP to its clients both domestic and abroad. And also, some LMP users purchase equipments from GN Solids Control when renewing their LMP, because comparing with tanks, the equipments is to some degree consumable. And also, lots of large tank manufacturers have established a long-term co-operation with GN Solids Control by continuously purchasing mud agitators and mud guns from GN.

460V/60HZ Decanter Centrifuge Used for 380V/50HZ?

Recently, several GN old customers asked GN for help, cause they wanted to use their GN decanter centrifuges designed for 460V/380HZ in condition of 380V/50HZ power source condition. Some of them purchased VFD control panel decanter centrifuges, some purchased fixed speeded centrifuges.

In order to meet their requests, GN electric engineer summarized below notes for instruction. Take GNLW363BG series centrifuges as cited example, cause this model is the most popular centrifuge of GN.

In case of fixed speed control panel centrifuge GNLW363BG:

For a fixed speeded GNLW363BG for 460V/60HZ, the standard speed is 3200RPM at 60HZ frequency. We can make it suitable for 380V/50HZ by adopting a transformer for the motors to be well functional, but the rotating speed will be less than the rated 3200RPM when the electric frequency is 50HZ, it would be around 2670RPM. In order to keep the ideal rotating speed, the end user need to add a set of pulley and belt for 3200RPM at 50HZ.

In case of VFD control panel GNLW363BG-VFD:

If the centrifuge is designed for 460V/60HZ with VFD control panel, in order to use it in 380V/50HZ, firstly, we need to add a transformer. But the transformer only enables the motor to be function well with new power source. But unlike the fixed speed, there is no need to adopt another set of pulley and belt. Only thing need to be change is some parameters in the control panel per GN engineer’s detailed instruction.

Besides this 14inch bowl decanter centrifuge GNLW363, GN Solids Control also has other centrifuges, nearly covering all necessary applications in field of solids control and waste management in drilling process. Like middle speed big bowl centrifuge GNLW452 for barite recovery, big bowl centrifuge GNLW453BG-VFD and GNLW553-VFD and baby centrifuge GNLW223 mainly for diamond drilling, and etc.

Centrifuge Feeding Pumps from GN

As the only China manufacturer who can produce both vertical cutting dryer and big bowl centrifuges, GN Solids Control has a wide range of centrifuge options. And, of course, the feeding pump is important, too. Besides main equipments for drilling solids control and waste management systems, GN also produce and provide feeding pumps for main equipments.

 Normally, for centrifuge feeding pumps, there are 2 options, which are submersible slurry pump and positive displacement pump.

  1. GN submersible slurry pump. In fact, submersible slurry pump is a vertical centrifugal pump, similar function and working principal as normal centrifugal pumps with a single suction system. GN series submersible slurry pumps are made of anti-abrasion alloy and capable of conveying high concentration particles. Because there is no bearing or seal between the impeller and pump body, there is no need to maintenance. And it can resist a comparably high temperature. It is not only ideal option as a centrifuge feeding pump, but also, it is always used as feeding pump for shale shakers of HDD or TBM mud cleaning systems for transferring mud from mud pit.
  2. GNG series Positive Displacement Pump, also called screw pumps. It is a standard option for centrifuge feeding purpose, cause it could stably feeding the centrifuge without stirring up the drilling mud. The most important parts of screw pump is rotor and stator, by their specially designed shapes of those parts, feeding capacity and pressure are steady. GNG screw pumps can be driven by variable speed motor and speed could be adjusted accordingly.

Besides above mentioned centrifuge feeding pumps, GN also produce highly cost-effective centrifugal pumps GNSB series and GNJQB series shear pumps. The centrifugal pumps are widely used for feeding desander and desilter in a solids control system and used as mixing pumps also.
