摘　　要：针对当前压裂酸化后转抽时间长,酸液或压裂液不能及时排出,对地层造成2次污染,影响油井产能的问题,研究开发了压裂后快速返排工艺技术。该技术是采用油井正常的采油方式(采用联作抽油泵和连续抽汲装置),实现一趟管柱完成酸化、压裂、抽汲及连续排液等工序,达到压裂后及时快速排液,减轻其对油层的2次污染,提高酸压增产效果。现场应用表明,该工艺实现了压裂后不动管柱排液求产,大大缩短了排液周期,减轻了工人的劳动强度,提高了试油效果,降低了生产成本。The quick-flowback technique after fracturing is developed in the light of the problems with the existing fracture acidizing technology. With this technique, the normal oil production mode is adopted, and the acidification, fracturing, oil pumping and continuous flowback are carried out on a single trip, resulting in timely and promptly discharging of the fracturing liquid and elimination of the second pollutions to the oil layer. The field practice approves that this technique can carry out liquid discharging and oil production without moving the pipe string, and greatly shorten the period of flowback and reduce the production costs.
