Compared with prior art, the beneficial effects obtained by the present invention are as follows being:
1. when turn on pump, first piston head stress, so that first piston column and second piston column move downward, at this point, spring
Forced compression, clinohedral are synchronized under the drive of first piston column and are moved downward, meanwhile, fin slides along the chute, with clinohedral
Gradually move, fin drive supporting block gradually flex outward, since pin rod is fixed so that second piston head swivelling chute with
It rotates under the cooperation of pin rod, as second piston head gradually rotates, so that supporting block both ends stretching, extension height changes, directly
Diameter is become larger by small；When termination of pumping, under the action of the spring, first piston column is moved upwards, so that supporting block retracts, so that
Drilling direction changes upwards, circuits sequentially back and forth, is switched by each turn on pump working condition of control stabilizer once, in drilling well
It is converted in due course in journey, to achieve the purpose that control effectively to well track；
2. setting through the invention changes the deflecting control energy of lower drilling tool by adjusting the size of stabilizer
Power, so that keeping minor diameter state in drilling process, avoids generation clamping stagnation existing to accurately control the hole angle of wellbore
As, solve the problems, such as stabilizer tight trip meet card, be inherently eliminated because pull out supporting block aspirate, caused by wellbore collapse
Collapse, the major accidents such as blowout, ensure that safety, can be avoided heavy economic losses, the invention can by opening, termination of pumping it is simple and
Quickly adjust, so can be accurately controlled to hole deviation, horizontal segment can by adjusting the size of stabilizer
To be accurately controlled TVD (vertical depth).
