摘要
水力喷射酸化技术是目前较新的一项储展增产技术,该技术既具有传统酸化压裂的特点又具有定向深穿透的优势,具有较好的发展前景。本文通过对水力喷射喷嘴外部流场进行模拟,对比单向流喷嘴外部流场和气体保护气液两相流喷嘴外部流场的速度分布云图得出,理论上气体保护气液两相流喷射效果更好,同时模拟得到影响气体保护气液两相流喷嘴外部流场的因素,为现场施工提供依据。
Hydrolic jetting acidification is a relatively new reservoir stimulation technology, which has good development prospects for its combination of both the characteristics of conventional acid fracturing and the advantage of directional deep penetration. By simulating the outside flow field of hydrolic jetting nozzle and comparing the velocity distribution nephogram of outside flow fields of unidirectional flow nozzle with that of two-phase flow nozzle with gas protecting gas and liquid, theoretically two-phase flow jetting with gas protecting gas and liquid proved better effects. Through simulation, this paper obtained the affecting factors of outside flow field of two-phase flow nozzle with gas protecting gas and liquid, which provided references for on-site operation.
