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.

Commonly used Drilling Fluid Treatment Process

Nowadays, the commonly used drilling fluid treatment process is as follows: firstly pump out into the liquid-gas separator in the drilling, degas in the liquid-gas separator, then enter the drilling fluid shale shaker to treat the larger particles of drill cuttings, and then enter the secondary solids control equipment mud cleaner, and the drilling fluid that meets the standard mesh is passed into the mud tank through the vacuum deaerator for use. According to different requirements, there may be mixing equipment in the middle. The processed drilling fluid can be stored in the mud tank for drilling use.

Drilling fluid plays an important role in oil drilling and horizontal directional crossing. The quality of drilling fluid directly affects the progress of oil and gas field development and the quality of oil and gas fields. The processing of drilling fluid affects the quality of the mud.( drilling fluid treatment process

Theoretical Research and Manufacturing Technology of Drilling Fluid Solids Control Equipment

In recent years, the theoretical research and manufacturing technology level of domestic drilling fluid solids control equipment has been greatly developed, especially in theoretical research on the working principle of shale shaker and cyclone separator, etc., which have reached a very high level.

drilling fluid solids control

The performance and quality of drilling fluid solids control equipment is the key to solids control technology. The drilling fluid solids control system mainly includes three parts: drilling fluid circulation tank, drilling fluid purification treatment equipment and electrical control equipment. Among them, drilling fluid purification treatment equipment mainly includes shale shakers, desanders, desilters, degasser, centrifuges, sand pumps, mud agitators and mixers, etc. It can also be equipped with drill cuttings recovery and waste liquid treatment device in environmentally sensitive areas.

KOSUN drilling fluid solids control equipment has the features of small footprint, high efficiency and long life. The solids control equipment system consists of 4 shale shakers and two dryers (namely drying shaker). The four shale shaker and dryers are connected in parallel. The drilling fluid returned from the well is distributed to the shale shaker by the drilling fluid distributor. The shale shaker and dryer are used for processing and recover the leached liquid and discharge the dried particles. The dryer is actually a fine-mesh shale shaker with a 10° tilt on the sieve frame to reduce liquid loss.
