Description
Technical field:
The present invention relates to a kind of continuous-tube drilling technology field, particularly a kind of continuous-tube drilling well cable turbine vibration resistance absorber.
Background technology:
Continuous-tube drilling well starts from the nineties in last century, and up to the present, the whole world uses continuous-tube drilling well more than 7000 mouth, and increases by 750 ~ 850 mouthfuls every year, applies more and more extensive.But because continuous-tube is bending and continuous-tube non rotating causes continuous-tube drilling well frictional resistance comparatively large, limit its range of application; Therefore, antifriction becomes the key that continuous-tube drilling well expands range of application.The thinking of continuous-tube drilling well antifriction avoids continuous-tube flexing and reduces friction factor, and major measure comprises use large scale continuous-tube, bores small size well, in drilling fluid, adds drag reducer and application antifriction tool etc.
At present, domestic still do not have the scene of continuous-tube horizontal well drilling to apply.Although the axial vibrator kind at present for petroleum drilling technology is a lot, some shortcomings of these vibrators existence more or less, can not meet the demand of underground work, the particularly particular/special requirement of continuous-tube horizontal well drilling operating mode preferably.Main cause has: (1) connects with hydraulic cylinder due to instrument hydrophthalmia, and therefore cable cannot pass through; (2) reset force of circular cross-section spring is poor, and vibrating effect is undesirable; (3) the high and pressure drop of power screw cost is large, and cable cannot pass through.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of continuous-tube drilling well cable turbine vibration resistance absorber, the arrangement achieves and facilitate cable to pass through, make tool string produce the vibration of high-frequency short arc in the axial direction, reduce the frictional resistance between tool string and well.Overcome existing axial vibrator cable cannot pass through, the deficiency that vibrating effect is undesirable.
The technical solution used in the present invention is: a kind of continuous-tube drilling well cable turbine vibration resistance absorber, comprises top connection, cylinder sleeve, rotating prevention sleeve, stop collar, jointing, the main cylinder of turbine and lower contact, top connection, cylinder sleeve, rotating prevention sleeve, jointing, the main cylinder of turbine is connected from top to bottom in turn with lower contact, central tube is connected to top connection lower end inside, central tube has the duct be connected with cylinder sleeve hydraulic cavities, between central tube and cylinder sleeve, disk spring is installed, disk spring upper end withstands on the step place of cylinder sleeve, disk spring lower end withstands on interstage sleeve, spacer shell is installed in interstage sleeve lower end, central tube is connected with rotating prevention sleeve by key, central tube lower end is connected with current limliting external threading, current limliting cover side, bottom has crescent by-pass prot, this crescent by-pass prot can be blocked or be opened to swivel head by rotating realization, swivel head lower end inner wall is threaded power transmission shaft, cable protective sleeve is through current limliting cover, swivel head and power transmission shaft, cable protective sleeve is built with cable, impeller is fixed on power transmission shaft by jump ring, guide wheel is fastened in the endoporus of the main cylinder of turbine, guide wheel is fixed on power transmission shaft by carbide alloy bearing.
All sealed by O RunddichtringO between top connection and cylinder sleeve, between central tube and cylinder sleeve, between cylinder sleeve and rotating prevention sleeve, between rotating prevention sleeve and jointing, between jointing and the main cylinder of turbine, between the main cylinder of turbine and lower contact.
The invention has the beneficial effects as follows: the present invention is owing to have employed disk spring and turbine apparatus as pressure difference-powered source, thus there is the advantage reducing screw rod pressure drop and facilitate cable to pass through, make tool string produce the vibration of high-frequency short arc in the axial direction, reduce the frictional resistance between tool string and well.
