TR Solid Control Equipment Co.,ltd

The function of a solids control system, regardless of the type of drilling fluid in use, is to separate drill cuttings from the drilling fluid so as to maintain the required rheology of the drilling fluid.

Shaker screens have capacity limits. Exceeding this limit means that mud will be lost over the screen(s).

Centrifuges – Centrifuges are of two basic types: low-speed or high-speed decanting, and fixed-speed, perforated-rotor machines.

Gumbo is formed in the annulus from the adherence of sticky particles to each other. It is usually a wet, sticky mass of clay, but finely ground limestone can also act as gumbo

Vacuum-type degassers separate gas from drilling fluids by spreading the gas-cut fluid into thin layers in a reduced atmosphere.

Solids control equipment should be arranged so that each piece removes successively finer solids as followed. Although all the equipment in the following list may not be needed, the most common arrangements are

Hydrocyclones – hydrocyclones are the next piece of equipment in the processing sequence and must process more than 100% of the flow.

Shale Shaker(s) – Shale shakers are vibrating screening devices and are fed by mud returning from the mud/gas separator or directly from the wellbore through the mud flowline.

The devices and associated tank arrangement in the removal region are: (1) Mud/Gas Separator, 2) Shale Shaker, (3) Degasser, (4) Hydrocyclones, (5) Mud Cleaner, and 6) Centrifuge(s).

The importance of removing drilled solids has been emphasized in modern drilling industy. The advantages of doing so may be summarized as
