Subway mud management and separation process

Mentioned the subway mud management and separation equipment, we should first understand the classification of shield machine.

一, the classification of shield machine.

(1) According to if the excavation face is closed:

  1. Closed 2. Open

(2) according to the different principle of balanced excavation surface earth pressure and water pressure:

  1. Closed shield machine can be divided into:
  2. earth pressure type B. mud type
  3. Open shield machine is divided into:
  4. hand-digging B. semi-mechanical digging C. mechanical digging.

二, the subway Subway mud management and separation process:

Mud-water balance shield machine is a device for mud-water separation in the shield. The mud is used to resist the water pressure, and earth pressure on the excavation face to keep the stability of the excavation face, and control the deformation of the excavation face and the foundation settlement. The mud film is formed on the excavation face to keep the water pressure effectively acting on the excavation face.

The management and separation process of KOSUN KD Series mud management system:

(1) Separation of most solid stones and clods by primary screening;

(2) After the first stage is separated, most of the large particles above 3mm are separated, the separated mud flows to the slurry tank, and then is pumped by the mud pump to the secondary cyclone for separation;

(3) The accuracy of secondary separation is in the range of 70-74μm. After the secondary separation, the slurry is again pumped to a three-stage flow separator for separation.

(4) Three-stage cyclone separation accuracy is in the range of 20 ~ 25μm, three separate mud flow back to the pulp pool;

(5) After the waste slurry is subjected to pressure-dependent separation by a filter press as required, the mud particles larger than 5 μm in the slurry are almost completely separated, and then the precipitate is discharged to meet the emission requirements. Through these 5 steps the mud particles and water are separated.(Editor:Kosun Lily.Wang)

The necessity of mud purification recovery

The necessity of mud purification recovery

During Non-excavation directional drilling, due to the diameter of a large hole, such as West-East Gas Pipeline and Jining pipeline project, with a diameter of 1016mm steel pipe, in the reaming stage, the amount of mud is very large.( mud purification recovery)

Rotary Drilling Rigs Slurry System
Rotary Drilling Rigs Slurry System

Usually, the non-excavation drill is through the open system, in the general through, the amount of mud are more than 3000 cubic meters, and some even reach 10,000 cubic meters. The amount of mud is large, not only increases the cost of mud and land acquisition, the more serious problem is that after the completion of waste mud if not effective treatment, pollution of farmland and water will cause ecological problems.

TBM slurry separation system

Introduction of the Main Equipment for Solid Control System

Recent years, with the requirement of high working efficiency in drilling industry, a new system has been designed and developed in some big solid control manufacturer, and the system is called “solid control system”. Kosun as the leading original manufacturer of solid control equipment and drilling waste management unit, the “solid control system” is not a problem for us.How to understand solid control system? As the professional solid control system manufacturer, we have our own understanding about this system.

Introduction of the Main Equipment for Solid Control System:

The first main equipment for solid control system should be the vacuum degasser,We could analytics from the function of vacuum degasser. Generally speaking, horizontal vacuum degasser will be used to separate the gas from the drilling solids. What’s the reason to do like that? Because we should do everything to prevent any dangerous elements in oil & gas drilling fields. That’s why we should put the vacuum degasser as the first role.

The second one should be mud cleaner. KOSUN MD Series Mud Cleaner is the second stage separation equipment for drilling fluids, which deals with the mud being treated by the first grade separation equipment. The barite will be recovered and cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the screens when the weighted mud passes while the particles that are bigger than mesh will be removed.

The third equipment, we think it should be shale shaker (with necessary steel frame shaker screen). Actually, after the drilling solids have been transported and fed into vacuum degasser and mud cleaner, the third step is going with shale shaker. Commonly, we still need to be transported the solids onto the shale shaker, or we could say onto the surface of shaker screen. The equipment of transporting we should use is centrifugal sand pump or screw pump; and we may use shear pump to cut the drilling solids into small one if they are in big size. With the different design of the shaker screen’s mesh, we could get the drilling solids separated in different sizes.

The fourth equipment should be the decanter centrifuge. KOSUN DC Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management. It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G. In solid control system, decanter centrifuge has been popularly used, which is also the popular one for drilling waste management. In this step, we could not only get the result of separating, but also we could separate the oil from the drilling solids, even if the oil is just a little part.

Of course, the whole equipment must be mounted on the top of drilling mud tank, which is a kind of basic equipment for both solid control system and drilling waste management (vertical cutting dryer is the core equipment for this system), but it is a kind of powerful equipment.

KOSUN was founded in Xi’an China in 1992. Up to now, KOSUN has formed a strategic layout integrating three centers and two industries. The Production, R&D and Domestic Sales Center is located in Xi’an China, the Overseas Project Management Center and International Trade Center in Beijing China and the Oilfield Services and Oilfield Engineering Center in Aktobe Kazakhstan in Central Asia. The two industries are traditional oil drilling solids control equipment manufacturing industry and integrated oil & gas drilling waste management service industry respectively.

Mixing and Grouting Plants, Mixing and Grounting Units and Stations

Mixing and Grouting Plants

Mixing and Grouting Plants or Mixing and Grouting unit（Mixing and Grouting Plants stations）are used in separation step during different projections, such as soil nails, tie-backs, soil mixing, jet grouting, grout compaction, vertical tie downs and injection grouting. Slurry obtained from field is not in its pure form.

It is usually mixed with particles and different liquids. Thus separation of these component in mixing and grounting plants is necessary. Kosun made system also give App end and PC control end to easily control the whole running.

Mixing and Grouting Plants
Mixing and Grouting Plants

For detailed phares in mixing and grouting plants(mixing and grouting units),the Separation of projection mud is done by the system which is an physical speparation flow.

Mixing and grounting stations

This Separation process is carried out by passing the slurry through an Separation. Mixing is brought in contact with the slurry at this time. High proportions of solids is scattered by shakers.

This process can be modified for extraction of specific slurry to increase its effectiveness. Extraction of other heavier slurry is up to 100% with use of this process. However for lighter solids, it is not an ideal process.

Mixing and grounting units

By the end of this process in mixing and grouting plants, 90 – 95 % of mud is obtained from the slurry stream. Move over, some energy is used to convert slurry from complex components into resuable slurry from by centrifuging it.

This decreases the cost associated with extraction of ethane from effluent. Thus separation of slurry from solids in mixing and grounting plants not only makes them pure and clean for use but also helps in obtaining valuable solids itself.

Fully understanding of the above detailed information will be hard, its a little bit different with TBM Separation plants or mine tailings treatment plants, but the real application case of the mixing and grounting plants is increasing the numbers day by day, some companies like Kosun from China have paid their attention on the related mechanics research. The performance is good, but still many progress can be achieved in the recent time. in the recent time.
