In the mud solid phase, we can in respect to their function can be broken into two classes. One kind is useful sound phase, including bentonite, chemical substance treatment agent, barite natural powder, etc; One more kind is useless solid phase, such as drilling waste, inferior bentonite, sand, etc . So-called going fluid solids control, is usually to eliminate the damaging solid stage, save useful solid period to meet certain requirements of drilling technology to drilling fluid performance.
The importance value from the solid control are getting focus, it has become a direct impact on protection, high quality and high efficiency going and water tank protection of important factor. Sound control is one of the important opportinity for optimizing drilling. Do a good job in solid control will provide necessary conditions for technological drilling.
Whenever we do the properly solids control can water tank protection, reduce drilling torque and chaffing, reduce the pressure fluctuation of annular pump, reduce the prospect of differential pressure sticking, improve drilling acceleration, extend the service life of drill little, reduce put on of equipment, pipe, improve the lifespan of wearing parts, going fluid blood flow system enhances the stability of borehole, enhance the casing conditions, reduce environmental pollution, decrease drilling costs, etc .
The scene statistical data present that inside the range of the lower density going fluid solid content in each lowered by 1%(itвЂs equivalently to reduce 0. 01 in going fluid density) average in soft development of transmission can be improved by 8% or so. Hence it can be found that do well the benefit gained by the hues control is extremely significant.
