Description
Technical field
This utility model relates to completion tool field, improves the water wheel type vibration cementing instrument of well cementation effect in a kind of well cementing operation.
Background technology
Vibration cementing technology is to be drilled an emerging technology in well field, and common vibration cementing instrument mainly has turbine type hydraulic vibration instrument, turnover plate type vibration tool and pipe internal vibration instrument etc. several；Turbine type vibration tool mainly utilizes hydro powered turbine to drive polarization block to realize the purpose of vibration, it is bigger that this vibration tool produces vibrational energy, but cyclic pressure dissipation is higher, improve the overall risk of construction, in addition turbine can not bear higher head pressure, when head pressure exceedes design maximum load-carrying capacity, self-locking can occur；Turnover plate type vibration tool is mostly installed at completion tubular column lower end, by periodically-varied circulating pressure, realizes the vibration of circulation of fluid in side；Pipe internal vibration instrument generally uses electric power as power, using cable to carry, the vibration ability that this vibration tool produces is relatively strong, but needs individually to carry out operation, and this instrument has completed well cementing operation when starting working the most, the lifting to well cementation effect is limited.
Utility model content
The purpose of this utility model is the problem existed for prior art, devises a kind of water wheel type vibration cementing instrument, to overcome turbine structure pressure consumption high and cannot bear the problem of relatively high water head pressure, can also obtain preferable vibrating effect simultaneously；Additionally, water wheel type vibration cementing instrument can play a role by the All Time in cementing operation, and image tube internal vibration instrument does not needs after well cementing operation completes to enter under individually, therefore has stronger practicality.
The technical solution of the utility model is:
A kind of water wheel type vibration cementing instrument, including overcoat and guiding gutter, upper cover, lower cover and the impeller being arranged in overcoat, wherein: guiding gutter is fixed on overcoat middle and upper part, impeller axle periphery is provided with several blade, the blade-section of impeller periphery increases the weight of to process composition deviation of gravity center axle centre structure, impeller is clamped in the overcoat of guiding gutter bottom by upper and lower cover, and impeller constitutes rotatable engagement with upper and lower cover, and upper and lower cover is provided with axial flow channels.
Such scheme farther includes:
Stagger between flow channels and the flow channels of lower cover of upper cover the angle of 90 °.
Impeller and upper and lower cover constitute rotatable engagement by bearing.
Guiding gutter, upper cover constitute the circumference spacing cooperation of grafting, are connected by upper retainer ring and lower retainer ring are fixing with overcoat respectively outside guiding gutter and lower cover.
During tool work, current enter from upper tool part, after entering guiding gutter, current become the circumferential eddy flow of downward spiral from axially circulation, when current arrive upper cover, being affected by constraint and the upper cover position of opening of guiding gutter, current will rotate into the space between upper cover and lower cover with higher speed；Because the position of opening of lower cover and upper cover have staggered 90 degree, so the liquid between upper cover and lower cover needs to rotate in a circumferential direction, certain position could flow out；Under the joint effect of guiding gutter, upper cover and lower cover, the liquid around impeller will rotate with higher speed, and impeller rotates, because its axial location of the deviation of gravity center of impeller, so vibration can be produced when rotating.
The utility model has the advantages that:
Tool construction is simple, and reliability is high, and waterpower utilization rate is high；The circulation mill resistance produced during tool operation is little, reduces construction risk, can play a role at the links of well cementation simultaneously, and tool utilization is high.Water wheel type vibration cementing can effectively overcome the defect of conventional vibration cementing tool, can obtain preferable vibrating effect, solve the turbine type vibration tool problem by maximum head pressure limit simultaneously in the case of cyclic pressure dissipation improves not quite.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
This utility model is mainly made up of several parts such as overcoat 1-1, upper retainer ring 1-2, guiding gutter 1-3, upper cover 1-4, impeller 1-5, lower cover 1-6, lower retainer ring 1-7.
Overcoat 1-1 is primarily served fixing internal structure and the effect of regular current, upper retainer ring 1-2 and lower retainer ring 1-7 and is connected with overcoat 1-1 by screw thread, is limited in the middle part of instrument by remaining part simultaneously；Guiding gutter 1-3 is used embedded and spot welding mode to be fixed in the middle part of overcoat 1-1 by upper retainer ring 1-2, the major function of guiding gutter 1-3 is the flow regime adjusting water, current are changed by flow direction during guiding gutter 1-3, the most downward axially circulation become rotating downward eddy flow；Upper cover 1-4 is arranged on guiding gutter bottom, being connected by slot between two parts, upper cover 1-4 primarily serves the effect limiting impeller 1-5 position, and upper cover 1-4 leaves flow channels simultaneously, guiding gutter 1-3 and the regular current of lower cover 1-6 can be coordinated, improve the waterpower utilization rate that instrument is overall；Impeller 1-5 is the movable part of instrument, is responsible for being converted into the kinetic energy of current vibrational energy, and impeller 1-5 is capped 1-4 and lower cover 1-6 and limits between the two elements, can carry out circumferential movement；Lower cover 1-6 is fixed on tool lower portion by lower retainer ring 1-7, plays the effect that impeller 1-5 provides spacing.
7 blades (such as Fig. 2) are had on impeller 1-5, three connected blade dimensions are wherein had to thicken and use heavy metal, i.e. as higher in steel isodensity metal is as material, the material of remaining four blade is the light-weight metals such as aluminium alloy, and such impeller just can produce the effect of eccentric vibrating rotating when.
The helical flow path that guiding gutter 1-3 and overcoat 1-1 is formed is entered after current are by the through hole of upper retainer ring 1-2, peripheral flow obliquely is become from axially circulation, current enter from flow channels A of upper cover 1-4 afterwards, flow out from flow channels B of lower cover 1-6 again, period impeller 1-5 rotates, thus producing rotation, current finally flow out from the through hole of lower retainer ring 1-7.
The flow channel of upper cover 1-4 and the flow channels position of lower cover 1-6 differ 90 °, and this structure can coordinate guiding gutter 1-3 to improve the impeller utilization rate to current circumferential movement energy, improves vibrating effect.
