The shield mud and water separation system has a good effect on the mud produced in shield construction. KD series shield mud and water separation system is a modular system. This shield mud and water separation system is designed to deal with various kinds of mud used in common shield construction technology.
Characteristics of shield mud and water separation system produced by xi ‘an KOSUN:
1. The whole series of vibrating screen, desander, desilter and centrifuge are all manufactured by xi ‘an KOSUN company;
2. Customized system and
standardized unit equipment can not only meet the needs of customers, but also
be stable and reliable;
3. High vibration force vibration screen, and high-speed frequency conversion large drum centrifuge to provide efficient muddy water separation capacity;
4. Double-layer vibrating
screen, which can effectively meet the processing capacity and save floor
5. Modular design can meet the rapid movement of the shield mud and water separation system.
Advantages of shield mud and water separation system produced by xi ‘an KOSUN:
1. Full purification of mud,
which is conducive to controlling the performance index of mud, reducing stuck
accidents and improving drilling quality;
2. Effective separation of
soil residue is conducive to improving the efficiency of hole making;
3. The reuse of mud is
conducive to saving pulp materials and reducing construction cost;
4. Closed circulation mode
of mud and lower slag water content are conducive to reducing environmental
Recently, 2 sets of ZJ15 fixed control system produced by KOSUN were successfully sent to the Ukrainian project site. Previously, KOSUN invited customers from the Ukrainian market to visit the factory to inspect the production process and work progress, and the customers gave a high evaluation of KOSUN’s professional products.
KOSUN production of ZJ15 drilling solids control system is a set of mechanical and electrical control of sludge treatment system, drilling mud can be hierarchical processing, at the same time, the drilling mud can be mixed, degassing, aggravating, mixing, can also be used to supply of wellhead mud, the Ukrainian market customer order system by mud mud tank, mixing tank, rotation of the crane and solids control equipment. The whole system includes vibration screen, vacuum deaerator two-stage solid control equipment, mud mix weight system, mud supply system, electrical control system, lighting system, etc. The surface coating of the system is durable, which can ensure that the system can be used in the wear and corrosion environment.
This ZJ15 drilling solids control system has several special designs of important processes, which can be used to grade drilling mud. The mud can also be weighted, mixed and stirred. Drug canisters and pipelines can provide slurry batching for the system; Mud system can be mixed and matched for system mud; Supply silo and supply line can supply mud supply for wellhead mud defect; Mud gun pipeline and mixing system can fully stir and mix in the mud tank; The clean water collection can provide water channel for slurry distribution and flushing tank surface.
ZJ15 drilling solids control system adopts multi-functional design, so that the system can meet the requirements of different mud systems, and each system and process can work independently or simultaneously.
The Balanced Elliptical Motion Shaker developed produced by KOSUN has obvious advantages in dealing with high-viscosity drilling fluid. In this case, the large particles in drilling fluid can be effectively removed through the balanced elliptical motion shaker track, and the relatively mild vibration intensity can effectively reduce the consumption of the shaker.
Balanced Elliptical Motion Shaker is the fourth generation of new mud shaker. In the past mud shale shaker mainly used linear shaker, but now more and more drilling companies choose balanced elliptical motion shaker.
With the development of drilling technology, drilling depth is getting deeper and deeper, and the requirement of mud is becoming more and more strict. Some complex geological conditions under the ordinary mud vibration screen cannot meet the requirements of use. And the performance of ordinary drilling vibration screen is not very stable, the effect of drilling vibration screen treatment will be different according to the drilling address and cannot adapt, often there will be some running slurry or “horseshoe effect”. The appearance of balanced elliptical motion shaker has solved these problems.
Advantages of Balanced Elliptical Motion Shaker:
1. The handling capacity
increases by 25%-30% compared with the linear vibrating screen;
2. Can adapt to a variety of
geological conditions drilling mud recovery and purification;
3. Excitation force can be
4. Linear vibration type has
the advantages of translational elliptical vibration screen;
5. Balanced elliptic
trajectory can effectively reduce the blocking phenomenon of sieve holes and
ensure the sieve penetration rate;
6. Help to improve the
cuttings transportation speed in viscous drilling fluid and prevent paste
7. Can handle high specific
gravity and high viscosity drilling fluid;
8. Longer screen life;
9. Drier cuttings;
10. Quick tensioning system,
easy to replace screen.
Dry sieve is used to recycle liquid drilling fluid shale shaker in the well site, dry vibrating screen or dry sieve is a kind of linear vibrating screen, in the process of drilling waste management is mainly used for recycling the main vibrating screen and hydrocyclone discharge of drilling cuttings adsorption in liquid phase, the recycling of liquid phase method is especially suitable for oil-based mud, can effectively reduce the waste mud.
Compared with the mainstream drilling fluid vibrating screen, the dry sieve mesh used in the drilling fluid drying screen will be larger. As the cuttings treated by the drying screen are relatively dry, high-frequency vibration motor is generally used as the power source for drying. This allows the recovery of drilling fluid through the screen slowly, coupled with strong vibration force, can maximize the recovery of drilling cuttings in the liquid phase.
Functions of dry sieve treatment system:
1. Reduce the liquid content
in cuttings and recover valuable drilling fluid, thus reducing the cost of
2. Reduce the total discharge of mud cuttings, thus reducing the waste slurry to be treated, so as to meet the requirements of environmental protection.
Application fields of dry sieve treatment system:
1. Dry cuttings for drilling
mud of various types, such as oil-base mud, water-base mud and composite base
