Platform.
Background technique
With the increase of directional well, cluster well and horizontal well quantity, drilling depth, environment temperature of the helicoid hydraulic motor in deep-well
Degree is continuously increased with pressure, and helicoid hydraulic motor promote the use of at home by each elephant, and achieves preferable drilling effect, but examine
Consider the reasons such as self structure, the usage mode of helicoid hydraulic motor, the helicoid hydraulic motor service life is shorter；When due to deep well drilling, depth compared with
Greatly, make a trip and expend that the time is longer, as helicoid hydraulic motor production or repairing quality the reason of cause to stop boring in underground, it will cause
Biggish time and economic loss；And helicoid hydraulic motor performance change under environment complexity and high temperature, it will cause helicoid hydraulic motor
Drilling efficiency is lower, or even situations such as failure.
