As shown in Figure 4, concise and to the point elaboration is below given.Start S300; Suppose that rotary drilling and slipping drilling carry out mutually, creep into curved section well, MTR and MWD instrument have been connected on S303 in bottom hole assemblies; Start rotary drill column, drill bit is circulated to rotary drilling flow velocity S305 the end of from; S307 stabilized (steady-state) speed, at rotary drilling rotating speed, stores from the collection of standpipe pressure sensor from end pump pressure and is presented at 44; Control winch and slowly transfer drill string, until the best creeps into pressure reduction or the best pressure reduction S309 of MTR, pressure differential deltap P=drill bit creeps into pump pressure-drill bit from end pump pressure (Δ P should be motor best effort pressure reduction), pressure differential deltap P is excessive or too small all inadvisable, cross conference and make MTR stall or damage, too smallly can not obtain good rate of penetration; Decision block S311 pressure reduction < Δ P? be less than turn back to S309 continue slowly transfer drill string, pressure reduction equal Δ P enter S313 with constant ground machine drilling speed control winch keep pressure differential deltap P creep into; Does is decision block S315 transformed into slipping drilling pattern? do not change and turn back to S313, continue to control winch with constant ground machine drilling speed and keep pressure differential deltap P to creep into; Be transformed into slipping drilling pattern and enter S317; In order to enter slipping drilling, driller slows down Top Drive RPM and turns/per minute to 0.5-2, keeps pressure differential deltap P simultaneously; S319 adviser tool face, monitoring drilling rod torque T

adata; Forward S321 to when tool-face angle is when the previous advance angle of target tool face angle, start to perform automatic torque rotating operation in the left and right torque limit set up; Meanwhile, keep pressure reduction at Δ P, S323 by controlling winch with constant ground machine drilling speed; S325 when tool-face angle stable close to target tool face angle time, perform slipping drilling by the method retaining tool face angle increased or reduce pressure reduction at angle on target; Too small or there is no pressure reduction if there is pressure reduction, illustrate and be subject to the impact of well frictional resistance, by adopting 60-70%T
lthe right-hand torque of value and the 60-70%T talked about below
bthe left-hand torque of value initiates automatic torque rotating operation, and Here it is, and moment of torsion of the present invention waves or rotating technique, reduces the longitudinal frictional resistance of well, transmits available weight, guaranteeing to continue slipping drilling under the prerequisite that tool-face angle is correct; If on the left of S327 tool-face angle > angle on target when 30 °, go to S329, with 1.1 or 1.2 times of T
lthe moment of torsion of value initiates right collision, and truing tool face angle is to angle on target to the right, returns S325 and continues through and increase or reduce the method retaining tool face angle of pressure reduction and carry out slipping drilling at angle on target; If on the right side of S331 tool-face angle > angle on target when 30 °, go to S333, initiate left collision, truing tool face angle left, usually, due to the effect of reaction torque, left-hand torque is much smaller than right-hand torque, and the moment of torsion of left-handed rotation drilling rod is generally that drilling rod torque T is rotated in dextrorotation
labout 60% of value, we are defined as T the moment of torsion of left-handed rotation drilling rod
b, i.e. T
b=0.6*T
l, therefore, the moment of torsion of the left collision truing tool face angle of initiation should be T
b, revise the tool-face angle of motor by the method that this left and right is collided, concrete operations are that the size that suitably can adjust left and right collision moment of torsion is attempted, (see SPE87162).Return S325 to continue through and increase or reduce the method retaining tool face angle of pressure reduction and carry out slipping drilling at angle on target; Does is decision block S335 transformed into rotary drilling? do not change and return S325 and continue through and increase or reduce the method retaining tool face angle of pressure reduction and carry out slipping drilling at angle on target; If want to forward rotary drilling to, go to S337 to stop transferring drill string, stop automatic torque rotating operation, until tool-face angle turns right Z ° (being generally 30 °-60 °), the Z ° of object that turn right allows a part of Bottom Hole Bit Weight In A bore before beginning rotary drilling, otherwise, if now at once the rotary drill column part drill string weight transmitting that shaft bottom can be caused to support to drill bit or bear by drill bit, drill bit the pressure of the drill can be made like this to increase and to cause motor stall or damage, bore this part the pressure of the drill before rotary drill column and can prevent motor stall or damage; Enter S339 after executing S337 to start top and drive rotary drill rod, until rotary drilling rotating speed, keep pressure reduction at Δ P simultaneously; Return S313 and control winch maintenance pressure differential deltap P rotary drilling with constant ground machine drilling speed.
Fig. 4 control flow is the process control that rotary drilling and slipping drilling are changed mutually, for top drive drilling, during exchange, when single upright column creeps into, drill bit continues to remain on shaft bottom substantially, keep pressure differential deltap P to carry out the mutual conversion of rotary drilling and slipping drilling, instead of and be transformed into from rotary drilling the traditional method that slipping drilling puies forward drilling tool, release drill string reaction torque and adjustment tool-face angle.During slipping drilling, use this cover ground controlled approach, not only can effectively control and truing tool face, the tool-face angle required is kept to implement directional drilling, longitudinal frictional resistance also by using moment of torsion rotating technique to reduce well, effective transmission Bottom Hole Bit Weight In A, makes directional drilling reach a desirable rate of penetration, realizes stable bit speed.Use this system can save certain nonproductive time, accelerate drilling progress, thus improve drilling efficiency.
Slipping drilling drill bit is from the end or conventional method that after making up a joint, tool-face resets: for a top drive drilling, often creep into about 90 feet (27 meters) usually to need afterwards to connect a new column, in this course, once after top drives and bored last 90 feet long drill rod stand column, 3 to 6 feet, drill string lift-off shaft bottom (0.9 to 1.8 meter), then, hanging is sitting in slips, prepare to connect the long column of next root 90 feet, by driller, a new column is received on drill string to the moment of torsion buckled to regulation, this process allows drill bit and MTR depart from shaft bottom, due to directional drilling before, on carry drill string it can be made to discharge uncertain reaction torque, the i.e. uncertain reversion number of turns, this makes tool-face angle be in a uncertain direction.In order to rebuild the tool-face angle of requirement before slipping drilling, directed driller must with on-the-spot driller's collaborative work, perform following steps:
1, by above carrying the moment of torsion accumulated in lowering drill pipes release drill string;
2, calculate an angular variation estimated, the reaction torque by motor produces by this angular variation;
3, on drilling rod, a vertical marker is drawn with chalk, as working base point or the baseline of an instruction MTR flash (bent angle towards), the expulsion of manual control top gradually rotates drilling rod, until obtain an angular variation of specifying to realize the object of directional drilling, and compensate the impact of the reaction torque estimated;
4, according to the tool-face reading information that measurement while drilling mwd system is passed back, the effect of this side-play amount is checked;
If 5 need, repetitive manual rotates drilling rod;
Get into the end 6 times, use the pressure of the drill and mud speed rate, then start slipping drilling.
Adopt method of the present invention, during slipping drilling, drill bit resets tool-face the end of from or after making up a joint: after making up a joint, directed driller can on carry lowering drill pipes, the moment of torsion be wound around in release drill string, then, directed driller uses tool-face dial plate (60 in Fig. 2) with a scale and oriented control system interface by tool-face towards the direction value required, dial plate shows real-time tool-face information, this direction value required can comprise surplus or the discount value of a reaction torque usually, once drill bit starts to turn clockwise with the pressure of the drill in shaft bottom, reaction torque can attempt to rotate counterclockwise motor, use man-computer interface operation can accomplish this step very soon, can reduce and operate relevant a large amount of invalid activity duration with current manual method.
Tool-face during slipping drilling controls: once slipping drilling, directed driller can monitor the real-time tool face data received from measurement while drilling MWD, all needs to intervene, the control in retaining tool face and correction from any change greatly of tool-face data.Utilize this cover ground control system, dynamically this point can be accomplished in time by the accurate angular variation needed for applying drilling rod, use man-computer interface, look at the reaction result of tool-face dial plate, when the time comes, if need to adjust the angular variation parameter of pushing up and driving, utilization axle offset controls, and implementation tool face is directed and control.
Retaining tool face after making up a joint: in slipping drilling, a main cause of invalid activity duration is that drill bit and motor are put back to shaft bottom, because now tool-face relatively goes up an equidirectional value when root post has been beaten, the traditional method of this process makes repeated attempts adjustment tool-face to correct direction, and this trial can expend a lot of time.Rotate drilling rod by the number of turns value of the revolution value or winding that provide a performance in real time and carry out tool-face control, oriented control system can save a lot of ineffective time, revolution is removed by this revolution value, this revolution value can also be used for rebuilding the tool-face be similar to very much when creeping into last time, confirm to remove the amount of spin of revolution needed for drilling rod, once after making up a joint under motor and drill bit to shaft bottom, driller can make drilling rod turn round simply, tool-face can bring back to and be similar to the tool-face before making up a joint by this revolution, the method in ideal tools face is kept after providing one to make up a joint.
The method of left-right rotation drilling rod is adopted to reduce frictional power: to use the method for left-right rotation drilling rod to reduce well frictional resistance and obtain abundant elaboration at SPE87162 document with the analysis of effectively transmitting the pressure of the drill.In directed drilling, increasing drilling rod lies in the downside of well, a drilling rod vibration agreement or program can be set, the man-machine interface of use system controls, realize clockwise and counterclockwise two-way drilling rod to rotate, this drilling rod vibration agreement or program when creeping into by real-time edition and amendment, can provide the control to amplitude and revolutions per minute vibration velocity, can implement accurately to set to the clockwise and counterclockwise rotation amplitude of multi-turn or winding or part circle or angular variation.Say in a sense, vibration program is the process applying neutral clean moment of torsion, any operation that drilling rod is rotated also can be removed, vibration performance can be unlocked, also can be closed, can not have an impact to other control ability of system, adopt axle offset control methods, during directional orientation tool face, drilling rod can be used regularly to vibrate or left-right rotation.
The present invention is by analysing in depth the characteristics of motion of drill string in oriented hole, and the friction mechanism of drill string and well, comprises static friction and dynamic friction, by literature query, analyzes and research, show that moment of torsion control principle significantly can reduce longitudinal frictional resistance of well.The present invention adopts moment of torsion to wave technology, is reduced the frictional resistance of drill string by the mode of left-right rotation drilling rod, revises and control tool face angle, transmits available weight, realizes directional well slipping drilling and automatically control, and improves slipping drilling rate of penetration and drilling efficiency.
In sum, content of the present invention is not limited in the above-described embodiment, and the knowledgeable people in same area can propose other embodiment easily within technological guidance's thought of the present invention, but this embodiment all comprises within the scope of the present invention.
