Embodiment
It is described with reference to make the utility model detailed description in detail below.As shown in drawings, it is of the present utility model
Structure includes body 1, valve seat 2, valve 3, spring 4, baffle plate A5, support set 6, eccentric wheel 7, baffle plate 8, fixed cover 9, steel ball
10th, separation sleeve 11, swivel head 12, it is characterised in that Multifunctional casing guiding device inner chamber have rotation trap tube module, eddy flow vibration
Well cementation three module compositions of module and unidirectional valve module, valve seat 2, valve 3, spring 4, baffle plate A5 constitute unidirectional valve module, gear
Plate 8, fixed cover 9, steel ball 10, separation sleeve 11, the composition rotation of swivel head 12 are trapped tube module, support set 6, the composition rotation of eccentric wheel 7
Flow vibration cementing module.
Body 1 along it is longitudinally fixed it is good after, in the inner chamber that support set 6 is inserted to body 1, the central shaft of eccentric wheel 7 is through branch
Eccentric wheel 7, is fixed in body 1 by support set 6 by the support fixation of support set 6, top and the support set 6 of eccentric wheel 7
Bottom contact.
Baffle plate A5 is arranged on the top of support set 6, and spring 4 is arranged on baffle plate A5 top, and the inner side of spring 4 is provided with all
You 3, and the top of valve 3 is provided with valve seat 2, and valve seat 2 is fixed with body 1 by frock and is tightened, and valve 3 is check valve,
When injecting drilling fluid, because the one-way valve structures of valve 3 promote valve 3 to be moved to bottom, when the bottom of valve 3 is contacted with support set 6,
Support set 6 stops that valve 3 continues to slide to bottom, so as to realize support set 6 to the spacing of valve 3, at the same time valve 3 and all
Space is formed between your seat 2.
Inject after drilling fluid, valve 3 is moved up and down between spring 4 and baffle plate A5, and the top of fixed cover 9 is provided with
Baffle plate 8, the bottom of fixed cover 9, which is provided with separation sleeve 11, separation sleeve 11, sets steel ball 10, and the bottom of separation sleeve 11 is provided with rotation
Rotary head 12, after rotation setting of casing module assembled is finished, is installed to the bottom of body 1, is tightened by screw thread.
Multifunctional casing guiding device bootstrap technique：The first step：In high angle hole and horizontal down-hole casing, sleeve bottom is set
Multifunctional casing guiding device is put, during guiding sleeve tripping in, swivel head 12 is rotated freely, due to the bias knot of swivel head 12
Structure, can effectively avoid obstacle, make sleeve pipe is smoothly lower to arrive projected depth；
Second step：After sleeve pipe reaches projected depth, drilling fluid is injected before cementing, during injection drilling fluid, because of valve 3
One-way valve structures, promote valve 3 to be moved to bottom, so that form space between valve 3 and valve seat 2, open passage, bore
