Fig. 5 B shows along the sectional view of Fig. 5 E section line AA.Nozzle retainer 808 and be illustrated and be located in the nozzle housing 801 with the nozzle of nozzle 809 as representative.Stator 803 and stator case 802 also are located in the nozzle housing 801.Surface 814 and 810 forms first inner chamber, so that apply swirling motion to the fluid of this part by stator module.Surface 812 and 814 forms the second inner cylinder eddy flow chamber, is used for the stable of this eddy flow slurries quality.The inner surface of stator case 802 forms outlet opening 811, and the fluid by the swirl stabilized chamber of cylinder is discharged out from outlet opening 811.The zone of outlet opening 811 provides such zone, that is, wherein the centrifugal force of eddy flow slurries quality is discharged along straight tangent line, forms the circular cone pattern of expansion.Fig. 5 C shows the lateral view of shower nozzle 801 and tubing string 200.Fig. 5 D shows the end view of shower nozzle 801.Fig. 5 E shows the end view of shower nozzle 801, wherein visible hatching AA.
Some embodiment of shower nozzle comprises the housing that is suitable for admitting removable stator module, and by the nozzle ports array of arranging around the shower nozzle outer periphery.Stator case has the inner passage of first cylindrical shape, and the stator rib is incorporated in to its surface in this inner passage.This column part becomes the conical portion of convergence, and this becomes the more cylindrical chamber of minor diameter again, and wherein the column part of tapered segment of Hui Juing and minor diameter has formed the spin chamber of stator module.Spin chamber's part of stator module is transformed into the cone shape outlet opening part of expansion.The relative size of stator module, flow channel, chamber and opening can be optimised, can be by changing the scope of the operating characteristics that slurry content and flox condition regulates so that generate.
In operation, slurries are by the passage that passes through from the tubing string pumping to be produced by stator rib and stator case, and it has applied angled swirling motion to slurries.The angle of slurries swirling motion and initial velocity are by the discharge angle of stator rib and total flow region control.Slurries flow to the convergence tapered segment of spin chamber from the stator passage, this convergence tapered segment has played applies the effect of axial flow velocity component for the eddy flow slurry stream, then because slurry stream flows in the circumference that has obviously reduced diameter, so the spin chamber accelerates to obviously higher rotary speed with the speed of eddy flow slurry stream, final slurries enter into the cylindrical mobile steady component of spin chamber.The slurries of eddy flow are operated according to angular momentum conservation law in the spin chamber, proceed to the littler diameter of cylindrical shape spin chamber part from spin chamber's diameter of maximum along with the slurry stream of eddy flow, the slurries rotating flow is stabilized in its maximal rate, and allows alluvium its speed of maximization before passing through the outlet opening zone of stator case.In the accelerating period of slurries, the drilling fluid component of these slurries will be with the speed eddy flow bigger than the speed of alluvium.Cause in the outlet opening zone that is transformed into stator case because of slurry stream before the change of eddy flow fluidised form, the time of staying of slurries in the mobile steady component of spin chamber allows drilling fluid to act on alluvium so that make the energy transmission maximization of this alluvium.
The high-speed rotational slurry stream changes and enters in the outlet opening zone of stator from the mobile steady component of spin chamber.Because hydrokinetic tangential release, so slurry stream has formed the cutting jet of Radial Flow, this cutting jet includes the alluvium and the stream of drilling fluid at a high speed of high relatively momentum.The high speed slurries have formed the conical cutting jet of radial expansion in the border of outlet opening, extend beyond this outlet opening then to form conical cutting jet, in case the energy of the alluvium of bump is reduced to certain level, promptly, the energy of the alluvium of bump can not further increase the diameter of pit shaft under current operating condition, then should the taper shape cutting jet be finally converted into the formula that enters again or re-entrant angle formula annular (reentrant toroidal) pattern.
Along with shower nozzle moves deeplyer,, force the low bottom of cutting jet of cone shape by pit shaft by the vertical action of shower nozzle in the quilt stratum of drilling.The depression conical surface of outlet opening is near the stratum bottom outlet profile of coupling, and the jet action by shower nozzle is cut the stratum bottom outlet profile of this coupling.The hydraulic action acting in conjunction of the conical surface of the depression of outlet opening and the cutting jet of high speed slurries, wherein this high speed slurries cutting jet is by between the stratum that further is defined in the outlet opening wall and is drilled by the vertical motion of shower nozzle, and wherein this shower nozzle tends to get in touch come together the physically neutralisation and stablize this shower nozzle of bottom outlet profile that the dissection by the slurries jet generates.Because during the drilling process not from the lateral forces of the operation of nozzle system on shower nozzle, so the centralization of the operation of this nozzle system and stabilizing feature can cause this nozzle system vertically to drill out straight hole naturally.For the expense that reduces the probing deep well, this is very important pit shaft structure aspect.
The alluvium momentum that is generated by the slurries speed advantage that generates in stator module spin chamber part in the cutting jet will be kept the speed of alluvium, and keep the kinetic energy of this alluvium thus, be used for the operating distance bigger than the operating distance of the drilling fluid that comprises in the slurries cutting jet.Discharged by hydraulic pressure so that delivering in pit shaft before entrained alluvium and stratum cut substrate upwards flow out pit shaft in slurry stream, the conical cutting jet that is formed on the expansion in the stator module outlet opening zone will finally form and enter formula annular fluidised form again.The leverage feature of the slurries cutting jet speed of shower nozzle fluid amplifier so that allow to use very little alluvium, satisfies the CFCS requirement that is used for stratum cutting purpose to the in addition leverage of the slurry stream supply pressure at shower nozzle place simultaneously.In case CFCS is exceeded by the effect of slurries alluvium, then provide ROP and set up the mineshaft diameter of target by the quantity of regulating the alluvium that clashes in the unit interval.The ejector in loop in response to by regulating alluvium size, admixture and slurry volume in case the dynamic requirements of setting up the target wellbore diameter and setting up target ROP subsequently come slurry content is regulated.
The ability that increases alluvium is used in combination the operating pressure of conventional rig available existing drilling fluid between the deep well tectonic epochs, allows to select and use littler alluvium, and this has increased the bump number of times of alluvium in the per unit volume.Use littler alluvium, for example, use the alluvium of US screen mesh size 25, when the flow rate with 12GPM is used for various embodiment with this alluvium, can produce about 275,000,000 bump of per minute, can satisfy CFCF with 0.025 inch nominal diameter.
In addition, remove by using littler alluvium also to obtain effective stratum, this is because the granularity on the stratum that the size of alluvium removes near the effect by alluvium more, thereby makes removing of stratum become more effective.This be because less alluvium with the cut mode impinge upon earth strata, and because depth of cut has applied higher impact force with the tight coupling between the alluvium diameter is feasible to the soil property stratum.Can remove the stratum in the shearing force mode more effectively than in the pressure mode, when using bigger alluvium particle, because not matching of alluvium and granularity can produce bigger impact angle of incidence, thereby can cause pressure.Therefore, use alluvium will generate the impact number of times still less of per unit slurry flow, and impact incident angle will cause impact energy still less to be passed to the stratum with diameter bigger than formation particles.In addition, from the granule impact thing of minimum be easy to carry about with one more, be easy to more cycle through high-pressure spray pipeline and fluid circuit, more be easy to recycle pit shaft, be easy to cycle through whole lowpressure stream pipe-loop and be easy to cycle through existing downward these viewpoints of jewel hole instrument more more, use minimum granule impact thing to expect.
Introduce the lateral force act on the shower nozzle (for example, being arranged on the vectored thrust that the result of the selectivity operation of the periphery jet in the shower nozzle generates) wittingly, be used for when the structure pit shaft, providing and aim at and the directed controlling organization of probing as use.Because there is not the requirement of drill bit weight or rotating torques for operation of the present invention, so (for example can use more cheap non-standard tubing string, shell and pipe fitting) so that reduce the loss of the parasitic pressure that circulates in the slurries in the tubing string, and flow and pressure characteristic in the wellbore annulus.Shower nozzle has the ability that produces the mineshaft diameter bigger than this shower nozzle physics external diameter, shower nozzle can be used to drill at high speed and/or dig a well tube downwards, so that be ready to pit shaft economically so that the saving of pit shaft structure, this can be used for being achieved by the making of single well-drilling borehole geometry of having adopted solid can expand shell method and/or the nested application of close tolerance shell.
