Oil and gas drilling solids control system including 4 phase of solids control and 5 phase cleaning equipment, the shale shaker, desander cones, desilter cones, decanter centrifuge and the various feeding pumps for those equipment, like centrifugal pumps, submersible slurry pumps, mono pumps and shearing pumps. And also, the vacuum degasser is within GN’s product range.
  2. Mud cleaning system for HDD projects. The main equipment used for HDD mud recycling systems are similar as the oil and gas solids control systems, especially recently, more and more centrifuges are used for HDD projects after the desilter A slight different is that, in case of oil and gas solids control system, the mud falls directly from the well mouth to the shale shaker, while in HDD project, there is a submersible slurry pump used for transporting the mud from the mud pit to the shale shaker. GN shale shakers are designed differently on the buffer box accordingly.
  3. Desander plant or slurry plant for Trenchless projects or TBM projects. The mud system or so called desander plant are similar with the HDD projects’ mud recycling systems. And the separation equipment to be used are chosen by clients’ respect. In some cases, the TBM Mud recycling system even use a decanter centrifuge or a dewatering system.

Structure and Applications of GN Desander for Oil and Gas Drilling

The desander would be the two-level solids handle gear used for drilling fluids treatment. As one particular in the indispensable and crucial devices for stabilizing and regulating those technical indicators with the drilling fluids, the drilling mud desander has also been extensively applied inside the purification in the drilling fluids.
Desander would be the second step in separation gear for treating drilling liquid. It separates solids and liquid treated after shale shakers, recycles the barite of weighted drilling and removes the surplus cuttings that happen to be larger barite particles. As the mixture of your hydrocyclone desander plus the vibrating screen, the drilling mud desander would be the three-level solids handle gear made use of in the solids control program on the drilling fluids. It truly is primarily created up of the vibrating screen, the distribution manifold at the same time as the hydrocyclones. The drilling mud desander is primarily employed to remove the damaging strong phase using the granularity of more than 45μm so as to make sure the fantastic properties with the drilling fluids.
The desander is mostly and broadly applied within the petroleum business, the oil and gas drilling, the exploration sector, the trench-less engineering, the geotechnical engineering, mining, metallurgy, coal as well because the hydroelectric business.
Structure of GN Desander
The desander system is created up of the screening system, the adjusting and supporting method, the aqueduct, the foundation, the pressure gauge at the same time as the desander hydrocyclones.
The desander is made around the basis of particle setting principle. The separated medium-drilling liquid enters along the inner wall of clone spirally, depending on the stress and speed created by centrifugal pump. Beneath the function of centrifugal force and gravity, the larger particles are sunk along the inner wall of clone spirally and drained from bottom outlet to be separated in shale shaker with smaller sized mesh. Other mediums are ascending along clone spirally to enter the second separation device from overflow outlet for additional purification.
Functions & Benefits of GN Desander
1. Polyurethane ( PU ) material or high-chromium cast iron for desander cones with longer using life.
2. Clamp type for easy maintenance.
3. Compact design with small footprint.
4. Flexible options for 1, 2 or 3 for different capacities.
5. Flexible fast connection is available for user assembly.
GN is a professional solids handle solution company which specializes in solids handle program,GN Service Co., Ltd,can serve the desander projects in the locality and its surrounding countries.

Gas-Flow Meter Measurement Program

Accurate produced-gas measurement although drilling

Engineered to measure the volume of gas developed though drilling, the GN gas-flow meter measurement method is actually a step-change innovation assisting operators decrease the atmosphere influence of their operations, including the carbon footprint. Also to measuring flow although drilling, the gas-flow meter is usually utilised for reservoir characterization by detecting and monitoring nuisance gas through tight-gas/shale gas, underbalanced-drilling, or managed stress drilling operations. The gas-flow meter is suitable offshore or onshore and is particularly effective in shale gas plays. The ability to explore the application of GN gas meter gas is very powerful, already have their own patents.

Real-time flow measurement and composition analysis

The gas-flow meter installs directly into the flare line to supply real-time accurate gas flow measurement and composition analysis. It has no moving parts, requires small or no upkeep and requires no personnel to operate when it really is installed. The gas-flow meter operates using a higher degree of accuracy in dirty or wet situations, and it will not protrude into the flare line or obstruct it in any way.


Detection capability for modest gas quantities

Standard desander designed for drilling operations lack the accuracy or reliability to detect modest quantities of gas, especially detrimental when drilling tight-gas formations. The gas-flowmeter offers the capability to accurately detect and quantify even the smallest gas flows down to 0.1 ft/sec.

Extremely accurate measurement technologies

Very precise ultrasonic gas-flow measurement technologies, combined having a precision stress and temperature sensing transducer, measure gas-flow velocity, temperature and stress to determine actual and regular volumetric flow, as well as mass flow rates. Data sent for the Drilling Rig Data Acquisition System enables direct communications with any capture device such as a data logger program, laptop, or hardwired or wireless memory stick.

Decrease environmental influence and reduce expenses

The gas-flow meter helps lower charges by quantifying the true production possible of formations whilst drilling underbalanced. Real-time reservoir information improves the decision-making course of action and potentially reduces overall exploration and improvement expenses. The   gas-flow meter makes it possible for operators to superior quantify and lower their all round environmental effect and carbon footprint. There are more on the GN’s official website describes the data and methods of measurement of gas flow meters, and look forward to your attention.

The Reasons You Should Go For Desander

The first time screen installation, you should inspect the screen dimension, such as 1250±2mm, the tolerance can’t over it. After fixed rubber strip, then put screen, shelve strip from shaker back (drilling fluid input), and push wedge evenly on two sides use hammer to push or tension wedges, make two sides identical. Tension each screens subsequently.

shaker screen replacement. During operation, when screens broken or need to be replaced, get wedge out, then bring out screen, check if rubber strips are sufficient; then put new screen on shaker deck and tension it steadily. The Desander is finished.

Shaker deck angle adjustment refer to fig V. There are bracket, fixed pedestal, worm and gear lifter, up-down chasingleader, etc. When adjustment, handle wheel rotary by clockwise, Solids Control will be larger; handle wheel rotary by anti clockwise shaker deck angle will be less.

operate the cuttings dryer system after long time off status

If we operate the cuttings dryer system after long time off status, we need to inspect motor rotary unit on insulation. Use 500V Ω gauge, get resistance is not larger than 0.5MSZ, we can run the shaker

Notice: ① If the motor doesn’t run at all, we must shut off the power immediately to avoid motor broken
② After starting motor, to inspect, whether this is any problem. If there is any break off or uncommon noise. If two motors are not running in-phase we need to stop the motors and get rid of problems then turn it on again for operation
③ When motor is under cold status, should not be started 5 times continuously; when motor is turned off under hot status, the restart can not be over 3 times continuously
Shaker screen maintenance
① Before every shut off, the shaker should run without any medium for 5-10 minutes, at the same time, use clean water to flush screen clean
② Every time finish operation, the shaker frame and screen should be flushed by water (summer) or steam (winter), there should be not much sediment on shaker frame and shaker screen. Especially when the drilling mud has large viscosity and high density or screen is finer than 60 mesh. Otherwise, the particles and fine sand on screen will block screen hole, when we start shale shaker, it will decrease filtration result and lead drilling mud flow away, lose much unnecessary cost.
cuttings dryer maintenance
Electric control cabinet is explosion proof magnetic starter, the electric principle is as fig VI, if there is any trouble we must shut off the power, and repaired by electrician or specific person
