摘要: 针对如何充分有效地利用井底的水力能量,既要能够提高水力能量的利用率,又要易于井下实现的问题,设计了一种新型的井下水力增压装置。利用井下环空流体对该装置分别进行了自增流量实验和射流瞬时动压力实验,并由此得出了实现最佳自增流量的开孔方案。实验结果表明:射流瞬时冲击力可以达到无孔时的2倍以上。

Abstract: The paper presented a new type downhole device of hy-draulic increasing pressure by itself, the hydraulic energy of downhole can be utilized effectively with this device. The itself increasing flow experiment and the transient jet dynamic pres-sure experiment by downhole annular fluids were described in
the paper, respectively, and the design program of the optimal itself increasing flow was drawn out. The results of the experi-ment were shown that the transient jet impulse from the holes-tapping conditions is more than 2 times of that of the none-holes.
