Backwashing Technology of Oilfield Filter and Its Development under the Action of Gravity Field
Aiming at low backwashing efficiency in applying the gravity field hydraulic backwashing technology to the treatment of the oilfield water produced,both the backwashing technology and its application progress under the action of gravity field were analyzed by means of mechanical assistance,air assistance and hydrochemical assistance,including the existing problems.The results show that,the future development trend of oilfield filter backwashing technology includes developing the supergravity technology to strengthen the hydraulic backwashing process of gravity field and constructing the supergravity backwashing system which has swirl flow field coupled with gravity field to break through the technical bottleneck of low efficiency of the gravity field backwashing alone.
