Solids Control Liquid Mud Plant (LMP)

In the Oil and Gas drilling area, for dealing with the drilling mud, there’s not just solids control systems and drilling waste management systems. But additionally, the liquid mud plants, also is known as LMP. Aside from the solids control system and drilling waste management systems, GN Solids Control also provide complete LMP or according tools available.

 What’s LMP?

 LMP is brief for Liquid Mud Plant, generally used beside a solids control system or any other mud systems for storage the drilling mud. To be able to avoid mud from settling, most significant tools utilized in LMP are mud agitators and mud guns. In a certain distance, usually every 3 meters, there’s a mud agitator and beside each agitator, there’s a mud gun. As well as jet mud mixing tools, like centrifugal pumps and mud mixing hoppers, utilized for adding and mixing the harmful chemicals towards the drilling mud and a preferred mud proportion.

 Using LMPs?

 Anybody using drilling mud in their projects or for their clients, could use LMPs. those companies consist although not limited to：

 1. Drilling company’s workers who provide their clients drilling service using their own rigs and solids control systems.

 2. Drilling Mud/Liquid companies, who don’t directly participate in drilling works, however they provide drilling mud towards the customers and reclaim the mud back and reserve it for next use.

 GN Solids Control offer LMP to the clients both domestic and abroad. As well as, some LMP customers purchase tools from GN Solids Control when reviving their LMP, because evaluating with tanks, the facility is to some extent consumable. At the same time, plenty of large tank producers established a lengthy-term co-operation with GN Solids Control by continuously buying mud agitators and mud guns from GN.

Soil and Liquid mixing tank

GN Solids Control is China leading manufacturer on mud solids control and drilling waste management system. They have experience on oily sludge separation. Recently, there are customers request V-bottom mud mixing tank for soil and oil liquid. The soil and oil liquid will go into the tank and they are mixed

The output line from the tank is a screw type (screw conveyor), so it can deliver the settled solid particles. And the height of the end of screw is 3 meter. Finally, there should be a liquid pump to transfer the liquid to other tanks or equipment.

V-bottom Screw + Shiftless conveyor

1) Solid/liquid mixture will be go into the v-bottom screw.

2) V-bottom screw and shiftless conveyor are put together and have sealing for no liquid leakage

3) Solid will be taken out from bottom screw – shiftless conveyor – and be discharged

4) Liquid will be pumping out from the top or making a hole at proper elevation

GN Solids control can provide tank and augers to meet the required function.

Below is a draft proposal made for customer’s reference.

1) Height of tank (including V-bottom) : 1.8 meter

2) Width of tank: 2 meter

3) Length of horizontal auger in tank : 24 feet long ( 7.315 meter)

4) Length of tilt auger: 24 feet long (7.315 meter), with tilting angle between auger and horizontal level 25 degrees.

Customer is satisfied with the proposal and mentioned more request. They want steam heating system for the mixing tank:

–       Steam injection nozzles (in this case, 2 nozzles each side (total 4 nozzles) can be installed and the nozzle would be positioned 0.5m from bottom)  

–       Wired screen (5 cm) on the top where operator pour the soil into the tank.

Per customer request, GN Solids Modification V-bottom Screw conveyor:

1. Steam injection line and nozzles inside

– steam injection line is split to two lines which are inserted into the v-bottom screw tank.

– 3 injection nozzles from each pipeline inside of v-bottom tank

– steam injection pipeline: 2 inch diameter (see picture below)

– no need of mixer inside

 

The Introduction on the Drilling Liquids

Drilling liquids has become broadly utilized in oil, gas drilling along with other drilling mud system. Using the solids control equipment, the drilling liquids might be recycled many occasions for cost saving and atmosphere protection. This short article gives an easy introduction around the purpose of the drilling liquids.

What’s the purpose of the drilling liquids?

1. Eliminating bottom from the well our prime pressure drilling liquids get out of the drill bit would flush the foot of the well make no obstacles for drilling process.

2. Carry cuttings – the drilling liquids would go ahead and take drilling cuttings to the floor surface for mud cleaning process.

3. Balance formation pressure – because of the very deep drilling, the drill bit can experience different formations for example rock formation and ground water formation. The drilling liquids here performed to avoid the floor water stepping into the drilling well. This could safeguard the geological structure.

Besides, the drilling liquids may also function to awesome lower and lubricate drill bit, safeguard borehole wall and supply downhole energy.

To completely have the drilling liquids advantages, you will find several needs around the drilling liquids.

1. The drilling liquids should meet interest in drilling mud recycling

Drilling cycle request the drilling liquids low pump pressure (low fluid viscosity), excellent capability to carry cuttings (dynamic pressure is high), low beginning pump pressure (low static shear pressure), good lube performance, low friction (less solids contaminants)

2. Keep up with the stability of borehole

It’s asked for to make use of drilling liquids column to balance the development pressure. So when drill oil and gas layer, the drilling liquids can also be required to balance pressure from the oil and gas. That will request a reliable density from the drilling mud.

3. Oil and gas protection

After drilling oil and gas layer, drilling fluid contacts with oil and gas. To avoid drilling fluid harmful the oil and gas layer, the drilling liquids ought to be small filtration, thin mud cake, low solid content and occasional filtrate of hydration etc.

4. Safeguard the character atmosphere

Drilling fluid frequently consists of oil and oil, diesel oil and a lot of chemical agents. To be able to avoid the possible effect on character atmosphere, non-toxic, harmless drilling liquids ought to be used.

 

Centrifugal pump Mechanical seal

There mainly 3 sealing types for centrifugal pumps, like shearing pump, sand pump , slurry pump, etc…

1) Asbestos packing

2) Arid seal

3) Mechanical seal

Mechanical seal is the greatest and many costive sealing types. It’s reliable with an extended lifetime.

The fundamental meaning of Centrifugal pump Mechanical seal

Mechanical seal is the seal device for rotary machines. Like centrifugal pumps, centrifuges, reactor along with a compressor equipment. Since the transmission shaft goes through within the inside and outdoors from the equipment, so, the presence of a circumferential clearance between your shaft and also the equipment, equipment of medium leakage outwards with the gap, when the equipment within the pressure is gloomier compared to atmospheric pressure, air towards the equipment inside leakage, and for that reason it has to possess a package to avoid leakage from the shaft. Many seal species, because of mechanical seal has the benefits of little bit of leakage and lengthy service existence and so forth, so in present day world, mechanical seal is sealed within the primary shaft from the equipment. Mechanical seal can also be known as the face area seal, within the relevant standards from the condition is understood to be: “by a minimum of a set of finish faces vertical with respect towards the axis of rotation within the fluid pressure and also the elasticity of compensation organizations (or magnetic) device function and coordination of auxiliary closes to help keep integrating carefully relative sliding form to avoid fluid leakage.

Review of concepts on Centrifugal pump Mechanical seal

Mechanical seal is as simple as a set of or number around the vertical axis for finish face relative sliding within the fluid pressure and also the compensation mechanism of elastic (or magnetic) under the act of coupled with keep adhering auxiliary sealing and leakage potential to deal with seal device.

Common mechanical seal structure comprises an immobile ring (static ring) 1, rotating ring (dynamic ring) 2, 3 elastic components, a spring chair 4, fastening screw 5, a rotating ring auxiliary seal ring 6, and also the static ring auxiliary seal ring 8 along with other components, anti rotation pin 7 is bound around the cover 9 to avoid static the rotation from the ring.

Rotating ring and also the stationary ring is frequently may also based on when they have been the axial compensation capacity and it is known as the compensation loop or non compensation ring.
