Shale shakers are the primary solids separation tool on a rig. After returning to the surface of the well the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the shale shakers the drilling fluid is deposited into the mud tanks where other solid control equipment begin to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.
Mud loggers usually go out and check the shakers for shaker samples that have circulated from bottom. They separate the shaker from the drilling fluid and take it into an onsite lab where they dry out the samples and label them according to depth. They then look at the samples and analyse what kind of rock they have at a certain depth. This helps determines what depth that type of rock was encountered.
As usual, due to metal "hard in hard" cooperate relationship easy to lead to the shale shaker wear and tear on parts when it in the process of running, for example, the shale shaker main shaft bearing wear and failure. After go wrong the above problems, the traditional enterprise solution is machined after repair welding or brush plating to repair, but both of the ways have some disadvantages: repair welding of high temperature thermal stress can not completely eliminate, neither repair welding thermal stress effect, repair the thickness is not restricted, and at the same time the product of metal materials do not have rolled back, and it also can absorb the impact of shaker equipment, avoid the possibility of wear and tear, and greatly prolong the service life of equipment components, save a lot of downtime for the enterprises, creating huge economic value.
Mud agitator adopt cycloid reducer under 5.5 kw, it is suitable for oil drilling fluid mixing, because it is compact structure and cover an area of an area small; More than 7.5 kw drilling mud mixer adopts turbine worm reduction drive, this type of mud agitator has three advantages which is big transmission torque, smooth operation, reliable work, etc.
KOSUN available drilling fluid solids control sand mud removal combined mud cleaner, it including the desander, desilter, pressure pump, hydrocyclone, underflow trough, drilling fluid shale shaker, bracket and base. The difference of characteristics in the desander and desilter main into the pipe and the liquid between a control butterfly valve,the base is equipped with the chute,the vibrating screen is located on the chute,hydrocyclone with automatic sand control device and bottom LiuKou adjusting device.
KOSUN has been the major supplier of solids control products in the field of China’s oil & gas drilling equipment, the earliest and only one decanter centrifuge manufacturer in five provinces in Northwest China, and the producer of the first-generation high-frequency drilling fluid shale shaker in China.
