In the trenchless construction, a large amount of mud and rock debris are produced. How to deal with the mud? This article will introduce common solutions for mud treatment in trenchless construction. Trenchless construction technology is a kind of underground engineering. Trenchless construction includes tunnels, micro tunnels (MTM), horizontal directional drilling (HDD) and other construction methods, also known as directional drilling, pipe ramming (PR), pipe jacking (PJ), underground drainage, horizontal drilling Boring (Habu) and other methods to install pipes and cables underground with minimal excavation. Large-diameter tunnels, such as tunnel drilling machines (TBM), drilling and blasting technology.

According to different construction methods, choose the appropriate slurry treatment equipment as an excellent slurry treatment solution, including: slurry treatment device (separation device), mud water separation station, mud recovery system, etc.

1. Large-scale tunnel drilling and shield construction (TBM). Due to the large diameter of the shield tunneling machine and the large amount of mud, large-scale slurry separation stations with large processing capacity are generally required. This type of slurry separation station is often through several sets of modularization. The slurry separation system is assembled, and the large-scale slurry separation station is used to treat the shield muddy water, which can process a large amount of 2000-4000 m³/h.

2. For the construction of small tunnels, micro tunnels (MTM), pipe jacking (PJ), etc., as well as the diameter of the pipe jacking machine, a slurry separation system with a processing capacity of 120-250m³/h can be selected.

3. For horizontal directional drilling (HDD construction), horizontal drilling and boring (HAB) construction, it can be matched according to the design of the mud pump processing capacity in the trenchless project or the drag force of the HDD trenchless drilling rig, and the processing capacity is 40- 250m³/h mud recovery system (recycling plant).

The above are three long-term effective non-excavation construction mud treatment programs. The selection of suitable mud treatment equipment for different trenchless projects is a prerequisite for scientific construction.

Treatment effect of five-level drilling fluid solids control system equipment

The drilling fluid solids control system is mainly used to remove harmful solid phases such as drill cuttings and recover useful solid phases such as barite. The solids control system is mainly composed of mud tanks, drilling fluid shale shakers, desanders, desilters, drilling fluid centrifuges and other major equipment, as well as auxiliary equipment such as mud pumps, slurry mixing devices, and vacuum degassers.

The mud tank is mainly used to store the mud and is the carrier of the solids control equipment. The mud purified by the solids control equipment enters the various chambers of the mud tank, and is processed according to different equipment, so as to achieve the removal of solid particles, recovery of barite, and purification of the mud.

The general processing flow of the solids control system: The drilling fluid shale shaker is the first-stage treatment equipment in the solids control system, which can remove the larger solid phase in the drilling fluid, and can remove solid particles above 74μm. The vacuum deaerator is used to remove the gas in the mud. It is the second and solid control device in the solids control system. It can quickly and effectively remove the gas contained in the mud. The deaerator is useful for restoring the mud density and preventing potential blowouts. It plays an important role in the occurrence of the danger of well collapse. The solids control equipment ranked at the third level is the drilling fluid desander. The mud treated by the vacuum degasser is transported into the desander through the sand pump. The drilling fluid desilter is used after the desander, which is used to remove the solid phase of 15~44μm to further ensure the performance of the drilling fluid.

In some solids control systems that need to save space, a desander, a desilter, and an underflow screen can be combined to form a drilling fluid cleaner, which can effectively remove solid particles larger than 15μm. In some uncomplicated drilling platforms, it can completely replace the desander and desilter. The final treatment equipment of the solids control system is a drilling fluid centrifuge, which is mainly used to remove solid particles smaller than 7μm and recover barite, with a recovery rate of 95-97%.

The solids control equipment is mainly used for complex well conditions and demanding well conditions. In the actual application process, according to the needs of drilling operations, one of the mud solids control processes can be used in one or more stages.

KOSUN’s Complete Shield Slurry Solid-liquid Separation System

A large amount of mud containing sand and rocks will be produced during the construction of slurry shield and pipe jacking. In order to protect the environment and save water resources, it is necessary to carry out solid-liquid separation treatment on the shield mud. KOSUN can provide a complete set of shield slurry solid-liquid separation system. The main equipment includes: shale shaker, de-sander, desilter, bottom drying screen, slurry supply pump, slurry circulation tank, etc. Slurry shield and pipe jacking are often constructed in cities, and the user’s construction site usually requires small equipment footprint and high treatment efficiency.

With the slurry shield and pipe jacking construction, the slurry is continuously purified through the slurry solid-liquid separation system, and ultrafine particles will continue to accumulate, which will eventually affect the shield and pipe jacking construction. Moreover, after the construction of the shield and the pipe jacking is completed, the waste mud also needs to be dehydrated. At this time, the high-speed large-drum slurry separator decanter centrifuge can play an important role. Through mechanical separation or mechanical and chemical flocculation and separation, the ultrafine particles in the shield slurry can be effectively separated, and the clean water can be discharged for recycling or meeting environmental protection discharge requirements.
