Description

Major diameter mechanical and hydraulic linkage formula enlarging while drilling device
Technical field:
The present invention relates to petroleum drilling technology field, particularly a kind of major diameter mechanical and hydraulic linkage formula enlarging while drilling device.
Background technology:
At present, domestic existing ripe reaming hole technology all belongs to reaming after finishing drilling, the mainly conventional reaming tool series such as bicenter bit, eccentric reaming drill bit, mechanical type PDC reamer and technology the extensive use of comparatively ripe reamer.In use there is inconvenience, as needs multiple trips changes instrument, have a strong impact on rate of penetration, part well section moment of torsion is comparatively large, and monolateral stressed, suppresses jumping phenomenon at violent compared with hard formation appearance, affect the application life of drill string and drill bit, easily occur ladder well, after expanding, hole quality is difficult to ensure, for follow-up casing job brings great risk.
Form enlarging while drilling technology series abroad, be divided into mechanical telescopic and hydraulic expanding.These two kinds of Counterboring apparatus all have the feature of length service time, but poor at Holes of Complicated Wells section stratum usage safety performance, and technological service expense is higher.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of major diameter mechanical and hydraulic linkage formula enlarging while drilling device, the arrangement achieves can safely, enlarging while drilling efficiently, improve well amplification degree, there is stronger stratum adaptive capacity, save construction cost, avoid multiple trips, save drilling time, improve drilling efficiency, reduce complex situations odds, ensure various complex structural well smooth construction.Overcome the reaming tool reaming borehole size that the exploitation of existing process of complex reservoir exploration applies little, rate of penetration is slow, the deficiency that complex situations are multiple.
The technical solution used in the present invention is: a kind of major diameter mechanical and hydraulic linkage formula enlarging while drilling device, and comprise body shell, body shell upper end is designed with top connection, top connection inwall connects catch ring, catch ring to be sleeved in the classification of center outside pipe upper end and spacing to pipe upper end in the classification of center, in the classification of center, pipe upper outside is set with convolution spring, convolution spring outwards suit convolution sleeve, convolution spring upper end withstands on catch ring lower surface, convolution lower spring end to withstand in convolution sleeve on step surface, wing is arranged on the main body external slideway of body shell by wing inner slide, convolution sleeve lower end withstands on wing and wing also can be made to regain body shell inside along main body external slideway, mechanical linkage pushing block to be sleeved in the classification of center on pipe, mechanical linkage pushing block withstands on wing and also wing can be made to stretch out body shell along main body external slideway, mechanical linkage pushing block lower end to be against in the classification of center in pipe outer step, body shell is connected on center classification outer wall of inner tube by shear pin, piston is arranged on shear pin lower end and is connected on center classification outer wall of inner tube, connecting ring to be connected in the classification of center on the outer wall of pipe bottom, between connecting ring with retainer ring outer wall, back-off gingival cyst of mucous gland in the newborn is connected, in the classification of retainer ring centering inside pipe, retainer ring upper end inwall is provided with ball seat, retaining ring is arranged on retainer ring lower end inner wall, body shell lower end connects lower contact, pressure regulator is placed in retaining ring lower end and is connected on lower contact inwall, pressure regulator inwall is provided with ball seat, the sidewall of the ball seat lower end of pressure regulator has pressure relief opening.
The invention has the beneficial effects as follows: the present invention can safely, enlarging while drilling efficiently, improve well amplification degree, there is stronger stratum adaptive capacity, save construction cost, avoid multiple trips, save drilling time, improve drilling efficiency, reduce complex situations odds, ensure various complex structural well smooth construction.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
As shown in Figure 1, a kind of major diameter mechanical and hydraulic linkage formula enlarging while drilling device, comprise body shell 2, body shell 2 upper end is designed with top connection 1, top connection 1 inwall connects catch ring 4, catch ring 4 to be sleeved in the classification of center outside pipe 3 upper end and spacing to pipe 3 upper end in the classification of center, in the classification of center, pipe 3 upper outside is set with convolution spring 6, suit convolution sleeve 5 outside convolution spring 6, convolution spring 6 upper end withstands on catch ring 4 lower surface, convolution spring 6 lower end to withstand in convolution sleeve 5 on step surface, wing 7 is arranged on the main body external slideway 10 of body shell 2 by wing inner slide 9, convolution sleeve 5 lower end withstands on wing 7 and wing 7 also can be made to regain body shell 2 inside along main body external slideway 10, mechanical linkage pushing block 8 to be sleeved in the classification of center on pipe 3, mechanical linkage pushing block 8 withstands on wing 7 and also wing 7 can be made to stretch out body shell 2 along main body external slideway 10, mechanical linkage pushing block 8 lower end to be against in the classification of center in pipe 3 outer step, body shell 2 to be connected in the classification of center on pipe 3 outer wall by shear pin, piston 16 is arranged on shear pin lower end and is connected in the classification of center on pipe 3 outer wall, connecting ring 12 to be connected in the classification of center on the outer wall of pipe 3 bottom, between connecting ring 12 with retainer ring 11 outer wall, back-off gingival cyst of mucous gland in the newborn is connected, in the classification of retainer ring 11 centering inside pipe 3, retainer ring 11 upper end inwall is provided with ball seat, retaining ring 13 is arranged on retainer ring 11 lower end inner wall, body shell 2 lower end connects lower contact, pressure regulator 14 is placed in retaining ring 13 lower end and is connected on lower contact inwall, pressure regulator 14 inwall is provided with ball seat, the sidewall of the ball seat lower end of pressure regulator 14 has pressure relief opening 15.
