Experimental study of suspended solids treatment in the oilfield sewage based on porous sintering metals

In view of the current treating status of the oilfield sewage containing suspended solids (SS), the SS in the oilfield sewage of Jianghan oilfield of China petrochemical was extracted, the parameters including the particle sizes and contents are tested. A set of test equipment is built up and the porous sintering metals are adopted as the filter material. The performance of sewage after filtrating the porous sintering metal under the gravity is tested, the effect of the sintering porous metal as the filter material in the suspended solids treating is verified. The results show that there are a great deal of blocks and filter cakes after the sewage permeating the porous sintering metal, the filtering effect is good, which provides methods and experimental basis for the treatment of the suspended solids in oilfield sewage.
