Abstract

The invention relates to the technical field of resource utilization of oilfield solid wastes, provides an interface material for dehydrating oilfield produced liquid as well as a preparation method and application thereof and further provides a lipophilic and hydrophobic type interface material which takes the interface material for dehydrating the oilfield produced liquid as a raw material. Theinterface material for dehydrating the oilfield produced liquid is prepared from sludge produced by an oilfield sewage treatment system, fly ash and cement. The interface material for dehydrating theoilfield produced liquid, provided by the invention, has the advantages of sable chemical performance, firm texture, low abrasion rate, strong lipophilic and hydrophobic performance and good dehydration effect; a preparation technology is simple and the interface material is applied to the field of rapid agglomeration and dehydration of the oilfield produced liquid; the environment pollution problem caused by the sludge produced by the oilfield sewage treatment system in an oilfield development process and industrial waste fly ash is solved, and produced wastes also can be circularly utilized;the interface material for dehydrating the oilfield produced liquid has the advantages of cost reduction, energy source saving and environment-friendly protection; meanwhile, the lipophilic and hydrophobic interface material can be used for the field of deep purification of oilfield sewage.

Description

technical field [0001] The invention relates to the technical field of resource utilization of oilfield solid waste, and relates to an interface material for oilfield production fluid dehydration and its preparation method and application, and also includes an interface material for oilfield production fluid dehydration as a raw material. Oil-hydrophobic interface material. Background technique [0002] The sludge produced by the oilfield sewage treatment system refers to the sludge formed by chemical coagulation to remove silicon from the oilfield heavy oil sewage before it is reused in the boiler. Because of its high silicon content, it is called the sludge produced by the oilfield sewage treatment system. The sludge produced by the oilfield sewage treatment system is extremely complex, mainly composed of oil-in-water (O / W), water-in-oil (W / O) and suspended solid impurities. , has always been a major problem plaguing the oil industry. In recent years, with the continuous...
