Fig. 1 is a bench drill well equipment, comprising one group of drilling rod 1, and is contained in the drilling tool 2 of its lower end.In the drawings, drilling tool 2 is in the operating position of drilling well 3 bottoms.Hollow drill 1 constitutes a very long conduit, and an end of this conduit is connected with the drilling tool 2 in shaft bottom, and the other end that is in ground is connected with conduit 4.Drilling mud injects the inner chamber of drilling rod 1 by conduit 4 with high pressure and constant flow rate.In order to make drilling mud inject drilling rod 1 with high pressure, constant flow rate, conduit 4 is connected with pumping plant 5, and the measurement mechanism 6 on the pumping plant is used for accurately measuring the pressure of pump.Drilling mud flows downward in drilling rod, supplies with the drilling tool 2 that is in the shaft bottom, upwards gets back to ground again by the pit shaft 3 of drilling rod 1 outside then.The bearing unit 7 of drilling tool 2 is connected with drilling rod 1 with telemetering equipment 8, and below parts 8, drilling tool 2 is installed on the drilling rod.The drilling mud of pressurization is as the working fluid of drilling rod 2.
Fig. 2 is an embodiment according to manipulation device of the present invention.By supplying with essential driving force, it just can be used for equipment of straighforward operation, for example, resembles the equipment of drilling tool bearing unit 7.This device is installed in the part 11 of the long duct that is made of drilling rod.Part 11 itself can be as the connector between the drilling rod, also can or install a part (device 7 can be connected with drilling rod) of 7 as drilling rod.The liquid stream of drilling mud flow to the drilling tool 2 that is in the shaft bottom from the hole 12 interior directions along arrow 13 in the middle of the hollow parts 11.The centre bore 12 of part 11 has an expansion 12a, and manipulation device just is installed in here.Manipulation device is made up of tubular surface differential piston 10, back-moving spring 15 and curved surface elements 16.They are arranged in hollow parts 11 vertically.
Press the flow direction 13 of drilling mud, the endoporus of differential piston 10 comprises two parts successively, i.e. its formation of first order throttling curved surface 17(intercepts and makes the fluid that enters conduit produce the pressure loss) and a curved surface 18.Curved surface 18 is truncated cone shapes, at its end a throttling part 18a is arranged, by a ring surface 18 with intercept part 17 and be connected.Curved surface 18 also can be columniform.Curved surface elements 16(or be called needle shaft) form by cone head 16a and afterbody 16b, by fixed mount 20 afterbody 16b is fixed in the part 11.Needle shaft has a centre bore 19.In other several embodiment of this device, needle shaft 16 can be made into does not have central small hole.
In guide hole 12a part (chamber of piston 10), be equipped with and be used for the O type seal 22 of packed-piston 10 and the front portion of piston 10 and stretch out guide 23.The purpose that guide is installed is to make piston be convenient to slide in conduit hollow parts 11, and leads accurately for piston in the scope of guiding aperture.Between the part 11 and piston 10 of conduit, also can use other mechanical connection manner.As shown in Figure 2, because the effect of spring 15, piston 10 turns back to the initial position near the figure left.When drilling mud with normal flow or when being lower than the control traffic flow of manipulation device, the active force of spring makes piston remain on initial position.
Because the curved surface of element 16 anterior 16a and piston inner hole profile 18 interact, and when piston moves backward, that is to say when moving from left to right among Fig. 2, make mobile drilling mud produce the significant pressure loss rapidly.
Fig. 6 is the working curve of device shown in Figure 2.Abscissa is represented the time, and ordinate is represented the flow Q of drilling mud respectively, by the pressure loss △ P of manipulation device and the stroke of differential piston 10.In a working cycles of manipulation device, flow Q is over time by curve 25(dotted line) expression, the variation of pressure loss △ P is by curve 26(solid line) expression, and the variation of piston 10 stroke C is by curve 27(chain-dotted line) expression.
The curve initial point represents that the flow of drilling mud is working flow Q
S, the operating point when piston 10 amount of movements are zero.
In order to use manipulation device, at the phase I T that handles circulation
AIn, increase the flow of drilling mud gradually, make flow from zero or Q
SBe increased to Q
ACT(pilot flow).When the phase I finished, the pressure loss at anterior 17 places of piston 10 curved surfaces reached value △ P
a, so, the unnecessary pressure on the piston front just produces a power, and this power begins to surpass the return force of spring, finishes stroke C so piston moves backward
1Flow remains on the QACT value simultaneously.When the second stage B of working cycles, along with the discharge opeing cross section of piston 10 slowly reduces, the pressure loss is at leisure from △ P
aValue rises to △ P
bValue.At this moment, piston 10 is at stroke C
1In make its curved surface 18 approaching with the curved surface 16a of needle shaft 16, pressure loss △ P increases sharply.Piston quickens motion backward at the C of working cycles in the stage.By pumping plant 5 controls, the flow value of remaining on Q of drilling mud
ACTAlong with the increase of the pressure loss, piston continues motion, finishes stroke C
2, up to colliding with the rear portion of cavity 12a.This moment, the pressure loss was from △ P
bValue changes to maximum △ P
mValue.The pressure loss increment that obtains like this is more much bigger than the pressure loss increment that only obtains with the dividing plate of fixed orifice.
Piston guide part 23 is connected with a moving element of device 7, gives 2 one orientation angles of drilling tool.
At other whenever, meanwhile or, the drilling mud pressure △ P that draws by the pipeline 24 of piston 10 fronts also can be used for a hydraulic pressure receiving device of manipulation device 7.If install 7 at constant flow rate Q
ACTUnder when moving, the power that is applied by piston 10 is not enough to continuous this action of keeping, then piston stop motion, the pressure loss no longer increases.△ P
i△ P
mOn curve, express one section stationary value (△ P
iThe pressure loss when being piston 10 stop motions).At this moment it is enough to make flow to reach and compares Q
ACTHigh value Q '
ACT, to finish the action of device 7.Max pressure loss occurs in △ ' P
m, △ ' P
mBe that flow is Q '
ACTThe time the maximum value (△ ' P of the pressure loss
m＞△ P
m).Flow can turn back to Q subsequently
ACTAnd remain on this value Q
ACTBe enough to keep piston 10 to be on the rearmost position.
As long as flow remains on Q
ACTValue, differential piston 10 just remains on the back location, and pressure loss △ P remains on its maximum value.
Flow reduced gradually being reduced to zero (stage E), piston turns back to initial position shown in Figure 2.Then, by increasing flow to working flow Q
SValue can drive drilling tool 2, and the equipment relevant with manipulation device is in new position.
In whole working cycles, make the flow rising and remain on Q
ACTValue is finished by pumping plant 5.Detect and the variation of the pressure △ P of record pump by measuring apparatus 6.Therefore, do not use remote control to control on the ground and be not difficult, particularly before release, just can detect easily and stopping that recording and analyses is moved, because at this moment produce a pressure plateau with the monitoring circulation.In this case, by flow being increased to the value of enough this devices of release, just can continue this action.Thereby pump installation 5 must be able to make flow reach the desired Q of ratio
ACTHigh value.Usually, in the whole working cycles of control device, be the unnecessary pressure representative corresponding to the pressure loss △ P function of time, so just can be used for determining the position of piston 10, thereby also can monitor the action of this device.Therefore, the tape deck of record pressure (function of time) is connected with measurement mechanism 6.After the action of controlled plant is finished, turn back to initial position, only need reduce the flow of pump to being lower than Q in order to make piston
SThe value of (but greater than zero).By increasing flow again to Q
S, drilling tool 2 again can controlled again work.
Fig. 3,4 and 5 is several embodiment in addition of manipulation device.
In Fig. 3, piston 110 here can be regarded as by a solid member and form; This solid piston has curvature portion 131, is used for and curved surface 130 interacts, and curved surface 130 is to process on the inner surface of drilling rod hollow parts 111, curved surface 130 play a part the obstruct part 17 shown in Fig. 2 and needle shaft 16 the two.Piston 110 has cylindrical part 110a, and the O RunddichtringO is housed on it, and piston moves in the inner chamber of cylinder 135.Cylinder 135 is contained in the shaft core position of drilling rod 111.The working chamber of piston 110 is subjected to from the pressure fluid of pipeline 134 inflows in the one termination, and pipeline 134 communicates with a ring-type inner chamber 133 at its other end, inner chamber 133 and drilling rod 111 coaxial lines, and utilize cylindric flexible piece 132 sealings.The drilling mud pressure that acts on pistons work chamber and the hydraulic fluid pressure that contacts with piston end surface and manipulation device upstream balances each other.In contrast, the pressure of the drilling mud that contacted of piston back is to cause the pressure that has reduced after the pressure loss by curved surface elements 130.
The assembly that is made of piston 110 and spring 115 is installed in the cylinder 135 with the form that seals, and is not subjected to the pollution of drilling mud.
This device is practically identical with the device mode of operation shown in Fig. 2, in case flow reaches Q
ACTIt is enough big that curved surface 130 caused pressure loss △ P just become, piston is moved along flow direction (arrow 113 directions), and 131 parts on the piston and the interaction between the curved surface 130 have increased the pressure loss again, make piston move to its terminal location.
As aforementioned, the drilling mud with excess pressure is used for handling the device 7 that links with conduit again by pipeline 124.
Fig. 4 is another embodiment, and each element that it will be identical with device shown in Figure 3 couples together, but the arrangement difference.The installation direction of cylinder 235 and piston 210 working chambers is opposite with the flow direction of drilling mud (arrow 213 directions).By annular cavity 233, there is pressure fluid complete and that drilling mud is isolated in the closed-loop path that the working chamber of pipeline 234 and piston 210 is formed, the curved surface elements 230 caused pressure losses can make piston reach Q at flow
ACTBegin during value to move.So the curvature portion 231 of piston just interacts with curvature portion 230, this is equivalent to intercept among Fig. 2 the two effect of part 17 and needle shaft 16.
The same as previously mentioned, surplus pressure △ P can be in order to manipulation device 7 by conduit 224.
Among the embodiment shown in Figure 5, piston 310 is tubular, and has two curvature portions 317 identical with piston shown in Figure 2 with 318().
Truncated cone curvature portion 318 interacts with parts 336, closes pipeline 337 gradually.Fixed mount 338 not only keeps pipeline 337 and drilling rod part 311 coaxial fully, but also plays fixed-piping 337 and parts 336.
In a single day flow reaches Q
ACTValue, piston just moves backward, and curvature portion 318 is close to compliant member 336, and the pressure loss is increased, and last piston 310 moves to till its terminal location.
At Fig. 3, in the device shown in 4 and 5, by flow being reduced to a certain value (can be null value), piston can turn back to initial position.
Fig. 7 represents a bench drill well equipment, and it comprises one group of drilling rod 51, in the lower end of drilling rod drilling tool 52 is housed.By conduit 54, the other end of drilling rod is connected with pumping plant 55.Under the work shape, pumping plant 55 is delivered to the drilling tool 52 that is positioned at pit shaft 53 bottoms to drilling mud by the inside of drilling rod 51.
The measurement mechanism 56 of measuring drilling mud pressure is housed on pump installation 55.
Fig. 8 is the overall pattern of stabilising arrangement (stabilizer), and sequence number is 57.This stabilising arrangement has a common tubular shell 60.This housing has taper hole 61a and 61b can couple together stabilizer 57 and drilling rod or drilling tool as 59 by screw thread at two ends.When stabilizer is connected with boring rod set, the center line 62 and the drilling rod central lines in the hole 63 of housing 60.Drilling mud flows according to the direction of axis along arrow 64 in drilling rod and stabilizer.
As Fig. 8 and shown in Figure 9, fluted 65 on the outer peripheral face of housing 60, its effect is to allow drilling mud to pass through from the outside of stabilizer in the process of returning ground from pit shaft 53.Also have several grooves 66 on the housing 60, its effect is to hold base plate 68.Fig. 4 and stabilizer shown in Figure 5 have three base plates 68, and they crouch in groove 66, and be uniform by 120 ° on the housing of stabilizer.On housing 60, the other end is supported on the end of base plate 68 one end of reed 71 by screw, makes these base plates radially keep retracted mode (as Fig. 8, shown in 9).Closure member 72 is contained in the end of groove 66, the outside of reed 71, and it play the guiding role in radial motion to base plate 68.Leave certain clearance between reed 71 and the closure member 72, allow base plate between position (Fig. 8 is shown in 9) of withdrawing fully and extended position, certain amount of movement to be arranged radially.The extended position of base plate 68 is by a pair of drive pin 69 controls, and drive pin is installed in the housing 60 and can radially moves.Each drive pin 69 can move, and with the O RunddichtringO drive pin is sealed in housing 60.
One tubular piston 75 is housed in the inner chamber 63 of housing 60, and for easy for installation, piston 75 is made up of two parts 75a and 75b, and the two forms sealed the connection by screw thread 76 with sealing mat 77.Piston 75 can slide in inner chamber 63 by the O RunddichtringO 78 at its part periphery and two ends.
At the end of piston element 75b, in parts 75a, be embedded with a body swivel bearing 80, an end of helical spring 81 withstands bearing 80, and the other end withstands block 82, and block is fixed in the housing 60.In the inside of piston element 75b,, a curved surface annular element 84 is housed in also at an end (arrow 64) that flows into corresponding to drilling slurry.
Second curved surface elements 85(or needle shaft) be contained on the axis 62 of housing endoporus 63.By the annular brace 86 that has the radial location frame.Needle shaft is fixed on the housing 60.
Drilling slurry when it flows into piston 75 inside through curved surface annular element inlet, will produce a pressure loss that changes with flow along the direction circulation of arrow 64.(be called and drive flow) under certain flow, the pressure reduction at piston 75 two ends increases power of generation and overcomes the power of spring 81, thereby makes piston 75 begin to axially move along the direction of arrow 64.The negative camber of curved surface annular element 84 interacts with the external surface of needle shaft 85, the overflow section of mud is reduced gradually, and the pressure loss is increased pari passu.When piston motion when the terminal point, it is very big that the pressure loss becomes, its corresponding numerical value can be measured at the pumping plant place at an easy rate by the pressure tester 56 that links with pumping plant 55.Like this, the motion of piston 75 can utilize the flow of pump to control, and the monitoring of carrying out on ground by pressure tester.
This teleoperator has very high stability, and this is to increase gradually in the piston motion process because produce the pressure loss of piston actuated power.
Being processed with driving skewed slot 90 and 91 axis directions along piston 75 on the lateral surface of piston 75 is separated from each other.Every group of skewed slot all matches with three drive pin assemblies 69 that are contained in base plate 68 1 ends.
With respect to the common axis 62 of piston 75 and inner chamber 63, skewed slot 90 and 91 is radially tilting by same trend.Point to when axially moving along arrow 64 at piston, this inclination can make base plate do radial motion.
With reference to Fig. 9, Figure 10 as can be seen, three tipper 90a, 90b on the periphery of piston 75,90c is tactic one by one, by these three continuous skewed slot 90a, 90b and 90c, base plate 68 just can be finished a complete motion cycle.The working depth at above skewed slot two ends is (with 10 on the piston 75
-3The rice expression) as shown in figure 10.Each pin 69 by spring 71 on the corresponding base plate 68 and the extremity piece that is processed into the circular support face, keeps the bottom surface contact with skewed slot 90.
As shown in figure 10, when piston moves along 93 directions, because pin 69 can make the bottom of pin 69 move on to absolute altitude-6 from absolute altitude-11 with the result that skewed slot 90a cooperates.Equally, skewed slot 90b makes pin move on to-4,5 from absolute altitude-6.Pin 69 is outwards done radial motion along housing 60 along the moving of skewed slot 90a and 90b along with these two, also outwards motion of base plate 68 simultaneously.In fact, as shown in Figure 9, the distribution of skewed slot on the circumference of piston 75 is such, promptly contacts at each all same group of identical skewed slot of pin 69 of the moment, and at each constantly, the motion radially of these pins is identical like this.Skewed slot 90c is corresponding to moving on to-11 with pin from absolute altitude-4,5, so it is corresponding to pin 69 being returned to original position and making base plate 68 turn back to the position of its withdrawal.
Like this, each pin 69 in the pin assemblies is all finished a complete motion cycle with three skewed slot 90a, 90b, 90c action.Therefore the skewed slot of constituent components 90 adds up to 3 * 3=9.
By Fig. 9 and Figure 10 as can be seen, skewed slot 90a, 90b, 90c are joined to one another by absolute altitude constant sweep 94 and straight line portion 95, form a continuous drive surface 96 on the circumference of piston 75.Sweep 94 couples together an end of skewed slot 90 end with straight line portion 95.Like this when piston 75 when a certain direction or other direction move to terminal point rotate because the pin bottom with the result of sweep 94 effects, makes piston 75 do stepping along arrow 98 directions.Each step journey is corresponding to the annular distance between skewed slot 90 and the adjacent straight line portion 95, just 360 °/18=20 °.
In one direction, the generation of driving force is the result of the drilling slurry pressure loss.And on another direction, then be the stored energy of spring 81.
Piston can only be done the step-by-step movement rotation along the direction of arrow 98, on the piston element 75b in housing inner chamber 63, slides and is adorning a pulley 100, by the key in the piston element 75b axial keyway 101 piston is consistent when rotated with pulley.Under the effect of mud and spring 81, piston 75 can be done axial reciprocating motion with respect to pulley like this.
Like this, under the effect of circulation drilling slurry, each group axially-movable that piston is done along arrow 64 all causes base plate to produce an outside radial motion (two continuous step journeys) and an inside radial motion (an axially-movable step journey).Because stroke that can the recording and analyses axially-movable on ground, therefore can determine the accurate position of base plate, so just can monitor stabilizer effectively by ten minutes.The mode of this record stroke is simple especially, sharply increases because piston all makes when reaching home vertically pump pressure produce once at every turn.
The method of operation of device is as follows:
When base plate is in the position of withdrawal, as Fig. 8, shown in Figure 9, a flow that equates with the driving flow of device at least is transported in the drilling rod, therefore causes the motion of piston and the automatic increase of the pressure loss, arrive terminal point, at this moment pressure loss maximum up to piston motion.Just can determine the terminal point of piston motion stroke by record pressure on ground.If the outwardly directed amount of base plate is enough big, only otherwise stop the input of drilling slurry, device will remain on this position automatically.If also will further base plate be extracted out, just must stop to import mud, under the effect of spring 81, piston is got back to the origin-location like this, and 20 ° of piston rotations meanwhile also are positioned at pin 69 on the planar section 95 of drive surface 96.At the end of planar section 95, the sweep 94 of drive surface 96 is by means of pulley 100, make piston in accordance with regulations direction rotate 20 ° again, at this moment pin 69 with next skewed slot 90b on a line.When the drilling slurry flow increased to the driving flow, piston 75 moved along arrow 93 directions, and pin 69 and base plate 68 move an additional step journey in radial outward.Clearly, after pin 69 passed through the planar section 95 and skewed slot 90c of absolute altitude-4,5 in succession, system will turn back to its original position.
All these move through the pressure record on ground and can intactly observe.
According to the present invention, the major advantage of manipulation device embodies in the superincumbent narration significantly: this manipulation device is without any need for remote control device, and this is because it is to carry out work and monitoring by pump and pressure tester that same very long duct is connected; It is simple especially and functional reliability is very high; Mode of operation also very simple and be easy to the monitoring; Be contained in during except installation the parts in the conduit, do not need any other parts.
If control stabilizer with this manipulation device, then the continuous motion of base plate on a direction or another direction can be monitored and carry out in very stable condition at an easy rate.In addition, the overall dimension of this device is smaller.
The embodiment that this invention is not limited to narrate above; On the contrary, it also comprises all other structural shapes.
That is to say that piston can have with above-mentioned different structure with the curved surface elements relevant with it.First order throttling curved surface can be relevant with piston, also can be irrelevant with piston.First order throttling curved surface can with second level throttling curved surface separately also can combine.The structure of these throttling curved surfaces can be with the difference of saying above.But their structure should guarantee the pressure loss of corresponding pressure/time graph and per minute maximum, and is corresponding because these two is the duty of the equipment relevant with manipulation device.
Making the device of piston reset can not be mechanical spring.As long as the mode of equipment receiving piston driving force differential pressure can be driving force to be passed to the driving part of equipment arbitrarily.
The working cycles of device can be with above-mentioned different, especially the pressure loss sharply increases the pairing piston rapid movement stage in the past, a stage that the pressure loss is very little can be arranged, so just might distinguish the motion stage and the quiescent phase of equipment significantly.
When coming the operation stabilization device with this device, the continuous skewed slot number of forming every group of skewed slot can not be 3, if finish that the step journey of a motion is less than or more than 3.Used base plate can be less than 3, if suitable, can be on the stabilizer only with a base plate, it can or use separately with other fixed support plate coupling.Or opposite, the base plate of employing also can be more than 3.Base plate can be arranged on the axis direction of drilling rod, also can tilt by coaxial line.
Yet, which kind of situation no matter, the number that the number of skewed slot must equal base plate on the driven plunger circumference multiply by the radially step number of passes of motion.
The mounting means of base plate and the structure that is adopted all can be with the differences of saying above.
Stop piston to rotate and allow the device that it rotates at other direction can be, and link to each other with piston with other device without pulley in a certain direction.
According to the present invention, drilling equipment allows to be equipped with a stabilizer arbitrarily, and each stabilizer can have a base plate arbitrarily, but has at least a base plate can do radial motion.
In a word, not only comprised the bearing unit of drilling tool or the device of stable drilling rod, and comprise casing bit or the device of Expansion sealing barrier film in well and in the boring that they have all utilized the effect of the superpressure that the pressure loss causes by the device handled.Manipulation device according to the present invention can be used for oil drilling, oil exploitation and other can not near or extremely inapproachable deep hole location, this device also can be used for distributing drilling mud.
