| 摘 要： | 针对煤层压裂过程产生的煤粉易造成煤层裂缝堵塞、影响裂缝的扩展等问题,考察了不同类型表面活性剂对煤粉的悬浮性能,综合考虑煤粉表面润湿性、工作液返排等因素,筛选出了合适的煤粉悬浮剂主剂,并进行了相关复配及性能研究.结果表明,煤粉悬浮剂的最优组成为:n(十八烷基三甲基氯化铵)∶n(壬基酚聚氧乙烯醚)∶n(乙醇胺)=1∶1∶1...

| Abstract: | There is much coal powder generated during coal-bed fracturing,which will block off coal-bed fractures and be harmful to the expansion of cracks.Considering coal surface wettability and flowbacking working fluid,coal powder suspending ability of different surfactants is investigated;suitable main agents of coal powder suspending agent are selected and compounded with some additives.The results show that the best ratio of octadecyl trimethyl ammonium chloride to OP-40 to ethanolamine is 1∶1∶1,the surface tension is 36.2 mN/m,the contact angle between water and coal powder treated with it is 86°,and the suspending percentage reaches 40.02% when the concentration is 0.3 g/L. |
