Coupling for solids control rotating equipment

Meaning of Coupling for solids control rotating equipment

Coupling for solids control rotating devices are utilized for the bond of two axes (the driving shaft and also the driven shaft), allow the 2 axis rotating together and also to transfer torque. Within the transmission of high-speed and high load rotating system, the coupling have purpose of buffer, damping and enhance the dynamic performance from the shaft. Coupling includes two parts, correspondingly associated with the driving shaft and driven shaft. The majority of the general energy machine by way of coupling using the work machine connected.

Solids control equipment with coupling design

Normally, the rotating speed with shaft or axis will require Coupling, like

1) Mud agitator: It's lower speed rotating equipment. Normally, the rate is just around 60 or 70 revolutions per minute. It's use to agitating the drilling liquids in tank and eliminates the mud from settle lower. Per different tank inner dimension, the mud agitator motor energy differs from 5.5hp ~30hp. In some instances, to be able to have more compact design, coupler may also be not used.

2) High-speed/low speed decanter centrifuge: It's high-speed rotating equipment with speed around ~4000 revolutions per minute. Decanter centrifuge is use high-speed to create high G pressure, and utilize our prime G pressure to split up the fine solids from drilling liquids. Is dependent on several centrifuge model, the separation point is between 2~5 microns or 5~7 microns.

3) Different model pumps: centrifugal pump, submersible slurry pump, screw pump, and so forth.

4) Screw conveyer for drilling cuttings transfer.

Along with other rotating equipment.

Classification of coupling for solids control rotating equipment

You will find many different types of coupling use for solids control rotating equipment, here is the standard model be utilized.

1) Flexible coupling

2) Teeth-shaft coupling

3) Universal Joint

4) Star formed elastic coupling

5) Plum formed elastic coupling

6) Pin coupling with elastic sleeve

GN had a large order from Kuwait client

GN Solids Control Co continues to be focusing on solids control devices and drilling waste management systems for several years, and lots of customers are keep get these solids control devices from GN each year because of the superb quality and be assured post sales maintenance.

Lately, GN Solids Control Co provides many teams of solids control devices for the client in Kuwait. This client has bought GN devices for his or her work over drilling rig. Whenever we cooperate with client at the start, we demonstrated our purpose to possess win-win cooperation by supplying solids control devices with higher quality.

Last year they gave us a sizable order which including 8 teams of GN shale shakers (the kind is GNZS594E-HB), 4 teams of GN vacuum degassers (the kind is GNZCQ 270), 4 teams of GN desander, 4 teams of GN desilter, 32 teams of GN centrifugal pumps in addition to 48 teams of GN mud agitators and eight teams of GN mud hopper.

For that shale shaker, we designed and manufactured a mud distributor for 2 teams of shale shakers, here it is called dual connection GN shale shaker. So our client has 4 groups Dual Shaker, with a large dealing with capacity, because even some GN shale shaker can dealing with the drilling liquids up to 616 GPM m3/h.

Depending on the above solids control devices, it's apparent to understand this can be a three phase solids control system our client really wants to use.

1. Shale Shaker

GN shale shaker can separate solids to 100 microns. For this kind of GNZS594, the dimension of shaker screens is 585mm X 1165mm, therefore the screens are exchangeable with Swaco Mongoose screens.

2. Vacuum Degasser

The mud originate from shaker will be delivered to vacuum degasser to get rid of the environment in drilling liquids. By utilizing GN vacuum degasser, the drilling mud could be stored inside a steady viscosity.

3. Desander and Desilter

GN desander and desilter can separate solids to twenty microns. The cyclones on desander and desilter are made from PU that is really useful to possess a very long time lifespan.

Drilling mud tank design concepts

The level of drilling mud tank must be big enough to support the utmost cycle amount of the drilling mud within the oil well drilling process, and also have enough mud reserve capacity.  Simultaneously the tank also provides the capabilities of taking part in cycle and manipulating the oil well just in case of the emergency. Recently, using the developing from the global marketplaces and also the growing need for drilling fluid solids control systems by drilling craft, the drilling mud tanks possess the need for boost the volume size.

When the drilling mud tank size is increasing, the price of moving drill rig and drilling fluid is going to be elevated too. Because of this, reasonable cubage may be the goal which went after by finish-customers. Based on the well drilling practice by many people years previously, it uses the technique of calculation of drilled well whole cubage or drilled well casing cubage to calculate the effective cubic consists of from the drilling fluid solids control system generally. The outcomes of these two techniques of calculation are believed.

In some solids control system, how big the only drilling mud tank and the quantity of the cycle  within the tank are made the decision through the height from the derrick substructure, the neighborhood transportation situation, and also the effective dealing with amount of the drill rig needed, etc...

The top mud tank must have enough space to set up needed solids control tools, mud agitator and drill rig transfer pumps. Furthermore, the configurations from the connected flow type of the drilling mud, add-ons, pump inhalation, water pipeline and just various tools needs be thought. The level of every storage mainly rely on the set-up space of solids control tools like shale shaker, desander, desilter, decanter centrifuge, along with other auxiliary devices too.

Geothermal energy drilling and Gas and oil drilling

Geothermal energy drilling and gas and oil drilling is extremely similar. Both of them use drilling rigs and special technologies to investigated subterranean assets.

Geothermal energy drilling features and clarifications

Geothermal energy drilling is really a drilling technology accustomed to exploration and growth and development of geothermal energy subterranean. Per different objective, geothermal energy drilling rigs drill different depth geothermal energy hole. Geothermal energy drilling is mainly used in gas and oil drilling rig or core drilling rig.

Based on the difference of liquids temperature geothermal energy drill, you will find below different kind of geothermal energy drill:

1) Cold geothermal energy drilling (warm water type), temperatures are less than 90 DEG C

2) Middle temperature geothermal energy (moist warmth type), the temperatures are between 100 to 150 DEG C

3) Hot temperature geothermal energy (steam type), temperatures are greater than 150 DEG C.

People pay increasingly more attention on geothermal energy assets and it is exploration. Geothermal energy assets can be used as energy generation, home heating, drying out industry, green house cultivation, artificial breeding and health, bath etc.

Gas and oil drilling features and clarifications

After exploration and located oil blocks/oil area, people use gas and oil drilling rigs and special equipment and technology to drill holes in surface selected, lower or side drilled a particular diameter round perforation, and drilling towards the subterranean gas and oil layer.

Per the drilling rig capacity on drilling depth, gas and oil drilling rig could be split into below fundamental models: 2000m drilling rig, 3000m drilling rig, 4000 drilling rig, 5000m drilling rig, 7000m drilling rig, 9000m drilling rig and max. 12000m drilling rig.

Based on the energy system size, gas and oil drilling rig could be split into below fundamental models:

1) Mechanical drilling rig, e.g.: ZJ50L drilling rig, ZJ40K drilling rig.

2) Electrical drilling rig: e.g.: ZJ70D drilling rig, ZJ50DB drilling rig.

3) Mixed energy drilling rig: e.g.: 40LDB drilling rig.
