Drilling mud treating system is for processing drilling fluids and,drilling mud treatment is for disposal Contaminated drilling fluids and mud.
GN Solids Control is one of about ten china manufacturers who can design and manufacture all the equipments for a complete drilling mud treating system
- Drilling Mud Treating System
To overcome many of the limitations of current solids-removal techniques, Drilling fluids mud-treating system was developed for weighted muds. The drilling mud or fluids treating system, called the Mud Cleaner, removes most of the drilled solids while retaining most of the barite and liquid phase of the mud. Unlike most barite-reclaiming or solids-removal techniques normally employed only after the drilled solids have reached an undesirable level, the Mud Cleaner is most effective when used as soon as barite is added to the mud system, and continuously thereafter. Continuous operation removes solids before they disintegrate to silt or clay size, thus preventing drill solids from accumulating in the mud treatment system. Briefly, the drillling fluids mud-cleaning system involves processing the mud through three separate stages:
(1) mud processing the mud through three separate stages: (1) mud at well-circulation rate flows through a first screen (shale shaker), which removes large-size solids; (2) the mud passes through a centrifuging stage (desilters), which passes through a centrifuging stage (desilter), which separates the mud into a low-density effluent and a high-density underflow – the effluent, comprising most of the liquid phase, returns to the mud treatment system; and (3) the underflow, containing barite and drilled solids, flows through a second, smaller screen that is sized to pass the barite but to reject most of the drilled solids. The first screen can be provided by a conventional shale shaker that usually has a screen size between about 10 and 80 mesh. For most wells, shaker screens finer than 80 mesh are not capable of handling mud at normal well circulation rates. This means that mud passing the shale shaker contains large amounts of drilled solids. These solids upset mud properties and are the most difficult to remove. By pumping the mud tough desilters and screening the underflow, a large part of these fines can be removed without appreciable loss of barite.
- Treatment of Drilling Fluids and Drilling Mud
Contaminated drilling fluids and mud are a considerable potential hazard to the sensitive marine ecosystem. The appropriate process treats the contaminated fluids and muds sufficiently so that by the end of the process, purified and thus unpolluted water can be discharged into the environment. This task is performed by the high-speed decanters and clarifiers from GEA Westfalia Separator.
Drilling fluids are understood to be viscous emulsions which are circulated through the drilling pipe during drilling for crude oil in order to pump the milled product upwards at the same time as the oil. These emulsions rapidly become contaminated with mud, salt water and oil residues. This means that the drilling fluids have to be continuously cleaned to ensure a smooth drilling process. The contaminated fluids are also a hazard to the sea, however, so continuous treatment is all the more important.
Once the drilling fluids have passed through a coarse screen and had a flocculant and a flush liquid added, the coarser solids are separated off by a decanter of the appropriate output. The liquid phase is initially passed to a slop oil tank. A clarifier from GEA Westfalia Separator then separates the fine residual solids so that the liquid phase can be discharged into the environment in the form of pure water after passing through a protective filter. This complies with the “zero emission”
