In order to further improve the comprehensive ability of functions of vacuum degasser for drilling fluids processing and Desander in terms of the energy consumption and product quality, the damage of oil and gas layer in many projects has to be reduced to a certain level. To do so, we need to select some oil layer protective agent to work with the functions of vacuum degasser for drilling fluids processing and Desander without any doubt under high temperature hot rolling because the viscosity of oil drilling fluid may not be able to meet the needs in practical application. According to scientific research results, proper elements must be added into the oil drilling fluid to produce good resistance to high temperature with an overall formula to achieve clay free drilling and completion fluid functions of vacuum degasser for drilling fluids processing and in spite of the fact that Desander system that is determined for more cost effective oil production. As a matter of fact, drilling fluid property is usually described with such factors as curve, viscosity, yield point and other rheological parameters of drilling fluid whatever the drilling temperature is.

To ensure that the property and building capacity of drilling fluid are stable, functions of vacuum degasser for drilling fluids processing and Desander must deal with the main pollution sources that affect the rheological property and filtration property of drilling fluid system. In view of this, to be more specific, the capacity of penetration resistance and soluble resistance of the 518 centrifuge has to be evaluated before we get to know the functions of vacuum degasser for drilling fluids processing and Desander. It is a truth universally acknowledged that when the system is added with increased filtration quantity, its plastic viscosity reduced while the yield point will be increased in the linear expansion rate so as to obtain the functions of vacuum degasser for drilling fluids processing and Desander as well as the ability to inhibit shale swelling, which is superior to the polymer drilling fluid in preventing clay hydration expansion from happening. Functions of vacuum degasser for drilling fluids processing and Desander have a good ability in terms of hydration expansion as well as mineral composition to avoid dispersion and migration of micro sized particles in the final oil products and the rolling recovery rate of the shale can be used to describe the functions of vacuum degasser for drilling fluids processing and Desander and its dispersion capacity in the entire drilling fluid system. The optimal clay free drilling and completion fluid system has been proved to be capable of effectively inhibiting clay dispersion and keeping good stability.
