Abstract

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.

Key words: drilling, boost device, laboratory testing, re-search
