摘要
水力压裂技术是油气井增产的一项重要技术措施。压裂支撑剂作为水力压裂技术的关键材料,其性能的优劣直接影响油气井产量。针对水力压裂技术中压裂支撑剂存在的问题,制备了一种环氧树脂压裂支撑剂,通过选择合适的环氧树脂、固化剂、增韧剂和中空玻璃微珠等为基础原料,并以与树脂相容性极差的甲基硅油作为反应载体,通过设计特殊工艺和成型设备制备密度≈1.1 g/cm^(3)的环氧树脂压裂支撑剂。所制备的低密度环氧树脂压裂支撑剂圆度为0.9,球度为0.9,强度高,具有较高的抗破碎能力(<3%)和酸溶解度(<0.2%),除此之外,可以直接用水作为压裂液,输送低密度环氧树脂压裂支撑剂,输送阻力小、输送距离远、支撑效果良好,有利于石油、天然气输出,提高产量,保护环境,能满足我国对低密度高性能压裂支撑剂的巨大需求,具有十分广阔的应用前景。
Hydraulic fracturing technology was an important technical measure for increasing production of oil and gas wells.Oil fracturing support,as a key material of fracturing technology,affected the production of oil and gas well directly.A new method for the preparation of fracturing support agents was proposed to overcome the existing shortcomings.By using the special processes and molding equipment,selecting epoxy resin,curing agent,toughening modification and hollow Glass Microspheres and so on,as materials,and taking methyl silicone oil as a carrier reaction medium,which had the poor compatibility with epoxy resin,a fracturing support agent with apparent density of about 1.1 g/cm^(3) was prepared.This low-density fracturing support has high roundness(0.9),sphericity(0.9),high strength,high crushing resistance(<3%)and strong acid resistance(<0.2%).It can be transported directly with water as fracturing fluid,which has the advantages of low transmission resistance and long transmission distance.Besides,it has an obvious supporting effect,which is beneficial to the output of oil and gas,the increase of production and the protection of environment.It can also meet the huge demand of low density and high performance fracturing proppant in China,and has a very broad prospect,market and application value.
