Shale Shaker for Petroleum Drilling Solids Control

Shale shaker is utilized in many different industries, such as coal cleaning plant, mining, petroleum drilling, and natural gas exploitation, etc. and the shakers that are currently used in petroleum drilling were initially introduced from the coal cleaning industry. It can remove the solids that is over 75μm diameter. As solids over this diameter is much harmful on the drilling fluids property. They must be removed from the drilling mud at the first stage of solids control system. And shale shaker with API 200 mesh (75μm) is designed and manufacutured basing on this principle.

I.  The Importance of Shale Shaker.
Shale shaker plays an important role in solids control system, and it is the most important and earliest equipment that are used to separate the solids in the drilling fluids. It is the first purification stage after drilling fluids return to the surface of the well, and has very strong effect on the drilling fluids property, specially on the cost of drilling. If the shaker screen that is to be used on the shaker is not correct, or worn, or even worse, the drilling fluids enter into the mud tank directly, but not through the screen, the equipments at subsequent purification stages may not work normally. This would definitely effect the drilling speed and the cost. So the drilling team must place and utilize the shale shaker in a right way according to the drilling mud property.
II. The Formation of Shale Shaker.
Shale shaker is consist of weled base, screen basket, screen, vibration motor, angle adjust device, feeder, explosion-proof switch, etc. Sometime in order to treat relative big volume drilling fluids, double or triple shale shakers are used, which two or three shakers are combined to work together. Drilling fluids first flow into the feeder, and then flow onto the screen. While the angle of screen basket can be adjusted -1° ~ +5° through the angle adjust device while drilling, no need to stop the drilling process. and the vibration motor, through driving its two pcs eccentric blocks retating, generates the vibration force on screen basket. So according to the diference of solids vibration tracks, shale shakers are divided into elliptical shaker, linear-motion shaker, and circular shaker.

III. The Nomenclature of Screen.
Before the new ISO standard was issued, shaker screens were named according to the screen mesh sizes.  The screen mesh sizes means the number of mesh per one inch length of the screen edge. At that time, most meshs are square, so this is advisable. After the new ISO standard nomenclature was issued, the British unit was not available any more. And also new complecated shale shakers were invented, these required the change of the shale shaker nomentacure. Normally API 20 meshes ~ 50 meshes is considered to be the cribble screen, and API 150 meshes ~325 meshes to be the fine screen.
