摘　　要：为解决传统原油化学破乳方法存在的处理能力不足、处理费用昂贵和环境污染严重等问题,利用油田脱水污泥及粉煤灰制备出强亲水疏油性的陶粒脱水材料,针对不同制备条件所得各材料的特性参数开展详细的比对研究,并实施室内脱水试验。结果表明:所制备出的20种不同的陶粒脱水材料受原料组分、处理温度以及黏结剂比例的影响表现出不同的材料特性和脱水性能;各种材料均不同程度地强化了原油的油水分离效果,经结合破乳剂的陶粒脱水材料处理后的原油含水率最低可降至0.5%以下;根据特性分析及脱水试验结果,确定5号材料为最优的陶粒原油脱水材料,其对应的物性参数为:与水接触角2°,与油接触角155°,筒压强度13.0 MPa,比表面积2.56 m^(2) g,孔隙率45%。In order to solve the problems of the traditional chemical demulsification of crude oil,such as insufficient treatment capacity,high treatment cost and serious environmental pollution,the ceramite dehydrating material with strong hydrophilic and hydrophobicity was prepared by using oilfield dehydrating sludge and fly ash.The characteristic parameters of each material obtained under different preparation conditions were studied in detail,and the dehydration test was carried out in the laboratory.The results showed that 20 kinds of ceramsite dehydrating materials had different characteristics and dehydrating properties under the influence of raw material composition,treatment temperature and binder ratio,and each material has enhanced the effect of oil-water separation effect in different degrees.After treated by ceramsite dehydration material combined with demulsifier,the water content of crude oil could be reduced to less than 0.5%.According to the characteristic analysis and dehydration test results,it was determined that ceramsite material No.5 was the best dehydration material for crude oil,and its corresponding physical parameters were as follows:water contact angle is 2°,oil contact angle is 155°,cylinder pressure strength is 13.0 MPa,the specific surface area is 2.56 m^(2) g and the porosity is 45%.
