摘要/Abstract

摘要： 稠油火驱化学点火过程中需要使用化学助燃剂,针对化学助燃剂存在储存及运输危险性高、成本高等问题,以生物质纸浆作为原料,通过低共熔溶剂-超声法制备了一种生物质基微纳米化学助燃剂(DES-US-BIO)。通过平均粒度及结晶度参数对DES-US-BIO的结构进行表征,开展燃烧池实验,进行了DES-US-BIO的活化能测定及燃烧特性分析研究,同时研究了DES-US-BIO的助燃性能。结果表明:所制备材料的平均粒径约为628 nm,其着火温度为240.0~260.0 ℃;燃烧阶段的活化能为69×10³~160×10³ J/mol;DES-US-BIO能够加速点燃原油,促进火线前缘温度升高进而提高原油采收率。DES-US-BIO的微纳米尺寸及低着火温度特性既满足注入要求,又能够提供初始点火能量并增加燃料浓度,使其在火驱开发的化学点火过程中具有极大的应用潜力。

Abstract: In chemical ignition for heavy oil fireflooding,chemical combustion agents are required.To address the high storage-transport risk and high cost of existing chemical agents,a biomass pulp was used as raw material to prepare a biomass-based micro-nano chemical combustion agent(DES-US-BIO)via a deep eutectic solvent-ultrasonic method.The structure of DES-US-BIO was characterized in terms of average particle size and crystallinity.Combustion cell experiments were carried out,including measurement of activation energy and analysis of combustion characteristics,and the combustion-promoting performance of DES-US-BIO was evaluated.The results show that the prepared material has an average particle size of about 628 nm and an ignition temperature of 240.0-260.0 ℃.The activation energy in the combustion stage ranges between 69×10³ and 160×10³ J/mol.DES-US-BIO can accelerate crude oil ignition and promote temperature increase at the combustion front,thereby improving the oil recovery efficiency.The micro-nano size and low ignition temperature of DES-US-BIO meet injection requirements and can provide initial ignition energy as well as increase fuel concentration,endowing it with great application potential for chemical ignition in fireflooding development.
