Main grinding and sealing elements in the power section of the present invention, such as blade bodies, wear resistant bodies and stator slide blocks, are made of soft metal or wear-resistant materials, and the elements with an automatic compensation function after abraded are structurally adopted. Thereby, the service life of the blade-type underground power drilling tool is extended, and the well depth application range of the drilling tool is enlarged, namely that the present invention is suitable for shallow wells or ultra-deep wells.
Description
The invention discloses a kind of blade-type underground power drilling tool, be applicable to oil, natural gas exploration, the exploitation in as mud motor; Also can be used as the mud motor in other drilling projects.
The disclosed Zina Garrison blade-type underground power drilling tool of in July, 1977 U.S. " gas magazine " adopts rubber as the groundwork element.At present, the permission serviceability temperature of rubber element is lower, and mar proof is also relatively poor, uses the increase of well depth and the raising in application life thereby limited this drilling tool.
The object of the present invention is to provide a kind of rubber of having cancelled non-refractory, having worn no resistance to make the groundwork element of drilling tool, and select the new-type mud motor that can compensate automatically after the groundwork component abrasion for use.This new-type mud motor has that suitable well depth scope is wide, the characteristics of long working life.
The present invention is achieved in that one by bypass valve (1), power joint (2), bearing joint (3), the oil drilling blade-type underground power drilling tool that pressure limiting valve (4) is formed, it is characterized in that: a. power joint (2) comprises shell (5), every liquid sealing frame (27), sealing ring (28), stator head (6), stator case (8), stator body (26), stator slide block (24), fixed system and main shaft (19) that stator reed (25) is formed, blade body (12), sharf (13), wear-resistant block (14), blade sheet spring (15), locating piece (20), backing pin (21), steel ball (22), dialing spring (9), dialing spring is steel wire (10) fixedly, steel wire cover (23), rotor head wear-resistant sleeve (16), rotor head positioning sleeve (17), the rotating part that rotor head clamping sleeve (18) is formed, its rotating part is positioned among the fixed system, and by two bush(ing) bearings (30) and fixed system are formed moving the connection up and down; B. be positioned at shell (5), have two inlet openings (7) in the upper end of the stator case (8) between liquid sealing frame (27), sealing ring (28) and main shaft (19), the lower end has two fluid holes (11), have the all-pass keyway (37) of two symmetries on the internal diameter, the two ends of stator case (8) are press-fitted by stator head (6) and shell (5) and are integral simultaneously; C. have the keyway (31) of two symmetries on stator head (6) internal diameter at stator case (8) two ends, the pawl (32) that two symmetries are arranged on the correspondence position of external diameter, two keyways (31) when assembling with stator case (8) on it flush with two keyways (37) of stator case, are positioned between shell (5) and the rotor head wear-resistant sleeve (16) at stator head (6) in the radial position; D. main shaft (19) is a hollow shaft, its endoporus (49) is a through hole, there is screw thread (46,50) at two ends, the middle part of external surface has the stairstepping elongated slot of four uniform installation blade systems--blade groove (29) and dialing spring groove (51), the two ends of blade groove (29) are provided with circular blind hole (47), the two ends of dialing spring groove (51) are provided with steel wire perforation (48), main shaft is positioned at the centre of shell (5) in power joint (2), its lower end links by screw thread and bearing joint (3), and upper end screw thread (50) is the nut fixed main shaft top part of screwing on; E. be positioned at main shaft (19) and go up stairstepping round tube hole (60,61) and the cylinder convex (62) that eight locating pieces (20) at notch cuttype blade groove (29) two are provided with biasing, the radius of curvature of its large curved surface equals the big footpath of main shaft radius, and goes up realization axially with radially spacing by cylinder convex (62) large curved surface and rotor head positioning sleeve (17) at main shaft (19); Make blade body (12) go up the location and form moving the connection by sharf (13), backing pin (21), the steel ball of placing in the circular hole (20) (22) at main shaft (19).Borehole pump boosts drilling fluid when ground, and when drilling rod is delivered to the outer shroud cavity (34) of this drilling tool power joint (2) (referring to Fig. 3), the high pressure drilling liquid inlet opening (7) through stator case (8) upper end again enters enclosed cavity (33), removing to promote blade body (12) clockwise rotates around the axle center of main shaft (19), blade body (12) promotes the drilling fluid on its right side again and arranges behind drill bit and outer ring space through the fluid hole (11) of stator case (8) lower end, flows to the desanding system on ground.Turning to liquid outlet (11) at this blade body (12) locates, its left side adjacent vanes body will forward the right side of inlet opening (7) to, and under the effect of dialing spring (9), blade body is promptly jumped out from blade groove (29), begin to take over last blade body (12) work, promptly drive main shaft (19) and clockwise rotate.So, four blade bodies alternately constantly carry out work, and main shaft (19) can successively rotate, and remove broken formation thereby drive drill bit, drill.
Blade-type underground power drilling tool disclosed in this invention, groundwork element in its power joint, promptly play element to mill and sealing, what all select for use as stator slide block (24,24 '), blade body (12,12 '), wear body (14) is soft metal or high-abrasive material, thereby overcome the deficiency of selecting for use elastomeric material to produce in the prior art, promptly deep-well creeps into, and bottom hole temperature (BHT) is higher than 120 ℃, rely on the drilling tool of the rubber work ability of will losing the job, the abrasion resistance of rubber is also relatively poor simultaneously.So blade-type underground power drilling tool disclosed in this invention has suitable well depth scope wide (shallow well or ultradeep well all can use), long working life.Simultaneously, because of this drilling tool adopts outer flow passage (outer annular space of drilling fluid in this drilling tool flows, rather than passes through in the axle center), it is long-pending to have increased cross section of fluid channel, has reduced the droop loss of drilling fluid, helps heavy duty service.
