Current drilling well is mainly by way of compound drilling and well dynamic tool slide creep into two kinds of drillings.Because these are multiple
Miscellaneous structure increases along journey hydraulic loss, and shaft bottom drill bit can be at a fairly low with water horse power, typically all by drill string own wt to brill
Head applies the pressure of the drill fractured rock.But in the wellbore construction of high angle hole, extended reach well and horizontal well, these traditional pressurizations
Mode is subject to certain restrictions, and its subject matter for existing is：
1st, because hole deviation is larger, component of the drill string own wt in well direction is small or is approximately zero, it is difficult to meet in advance
The pressure of the drill of design；
2nd, in horizontal well, because drill string own wt is big to the normal pressure of the borehole wall, frictional resistance of the drilling tool on the borehole wall is increased,
So as to constrain to applying effective the pressure of the drill on drill bit；
3rd, it is past because the horizontal segment constructed is more and more long, but in the big well section work progress of hole deviation for horizontal well
It is past that the phenomenons such as backing pressure, viscous card occur；
4th, for compound drilling, especially in well dynamic tool slide drilling process, it is impossible to ensure to apply to drill bit
Truly, effective the pressure of the drill, has a strong impact on full well average rate of penetration and drilling period.
The appearance of problem above, will all cause mud oscillation amplitude small, easily produce deposition, drilling tool clamping stagnation finally occur
Phenomenon.
