What solids control equipment will be used in oil drilling
Solids control equipment used in oil drilling:
Linear motion mud vibrating screen: As the first-level solids control equipment for drilling fluid treatment, it is used to remove other harmful solid particles such as cuttings in the drilling fluid. The drilling fluid selects different numbers of screens to control the size of the particles, mainly solid phase particles larger than 74μm.
Cyclone separator (desander, desilter): Desander is a secondary purification equipment for drilling fluids. Desander is mainly used to remove sand particles larger than 44~74 μm. The desilter is mainly used for three-stage purification of drilling fluid, and the desilter mainly acts on mud solid particles above 15-44 μm. Microcyclones can also be selected according to the actual conditions of the drilling fluid, which are mainly used to separate muddy solid particles above 2 to 4 μm.
Drilling fluid centrifuge: The function is to control the clay particles in the well fluid, control the solid phase of the drilling fluid, remove the solid content of the non-aggravated drilling fluid, and recover the barite in the aggravated drilling fluid. The drilling fluid centrifuge mainly acts on solid particles of 2 to 4 μm.
Vacuum degasser: The vacuum degasser is mainly used to remove the gas invading the drilling fluid. It does not belong to the scope of solids control. However, since gas invasion has great harm to the specific gravity, viscosity performance, and density of drilling fluid, degassing devices are usually used.
Petroleum drilling solids control equipment and solids control system are equipment and systems that process and recover the drilling fluid (mud) returned to the surface from the wellhead. The solids control system can effectively separate the large drill cuttings, barite and other large solid particles returned to the surface (mud) from the wellhead, and the treated drilling fluid (mud) can be reused. Thereby reducing the cost of drilling, and is conducive to environmental protection.
