Analysis of Downhole Instrument Damage Mechanism by Harmful Solids and Solids Control System Solutions
In modern oil drilling, especially in deep and extended-reach drilling (ERD) operations, the management of solids content in drilling fluids is not only about mud performance but is also a core variable determining the lifespan of expensive downhole tools. As the kidney of the drilling rig, a premium Solids Control System is responsible for removing harmful solids and protecting precision instruments. Erosion Damage Mechanism of Harmful Solids on Precision Downhole Instruments During the drilling circulation process, drilling fluids inevitably contain a large amount of rock cuttings. According to research reports on the impact of sand content on downhole tool reliability published by the Society of Petroleum Engineers (SPE) , hard solid particles with a diameter greater than 20 microns are
