水力压裂技术已可用于水平井 ,主要是套管井。在裸眼水平井中 ,尤其存在天然裂缝时 ,大而裸露的井壁表面会使大量流体损失 ,影响增产措施的实施。最近推出的水力喷射压裂法可以在同一油井中不使用密封元件而维持较低的井筒压力 ,迅速、准确地压开多条裂缝。油藏的最佳裂缝延伸? Hydraulic fracturing techniques have been used for horizontal wells, mainly cased wells. In open-hole horizontal wells, especially in the case of natural fractures, large and bare borehole surfaces can cause significant fluid loss, affecting the implementation of stimulation measures. The recently introduced hydraulic jet fracturing method can be used to maintain a low pressure in the wellbore without the use of sealing elements in the same well, and to quickly and accurately crush multiple fractures. The best reservoir of cracks to extend?
