The specific embodiment
Permanent the pressure of the drill automatic bit feed
The expert of various countries, scholar have obtained a plurality of about the pressure of the drill, the isoparametric mathematic(al) representation of drilling speed on the basis of various drilling experiments, but with strongest influence power and authoritative is the drilling speed pattern of Young F.S. proposition in 1969, being called poplar lattice pattern had the people that this is revised afterwards, just the correction poplar lattice pattern that extensively adopts up till now.That is:
In the formula:
V------send the drilling speed degree
K------drillability of rock coefficient, relevant with formation hardness and bite type etc.
C
P----pressure reduction influence coefficient, relevant with mud density etc.
C
H----hydraulic parameters influence coefficient, with more relevant than water-horse power
The W-----Bottom Hole Bit Weight In A
By above-mentioned formula, as can be known under same strata condition, K, C
P, C
HSubstantially be constant etc. parameter, then send drilling speed degree V and actual the pressure of the drill to take advantage of proportional relation, namely guarantee that as needing the pressure of the drill is stable, drilling speed must need to stablize, therefore from the mathematical theory analysis, send the control accuracy of boring the pressure of the drill to be directly proportional with sending the drilling speed degree, therefore only controlled well and sent the drilling speed degree, send brill the pressure of the drill just can meet the demands.
In the During Bit Automatic Feeding, because the pressure of the drill feedback lags behind, traditional PID control can cause the overshoot of system very large, and final control result send the drilling speed degree to be in periodic duty, cause sending brill the pressure of the drill precision not high, in order to overcome feedback hysteresis problem, in traditional PID control system, increased the artificial intelligent judgement, reduce the overshoot of system, by like this, can make and send the stable operation of drilling speed degree, improve drilling quality, guarantee the smooth of the borehole wall.
Permanent drilling speed automatic bit feed
System adopts pid algorithm to realize closed-loop control by judging the deviation of setting drilling speed and actual drilling speed, guarantees to send the drilling speed degree constant.
Permanent pump pressure automatic bit feed
In the horizontal well drilling process, because detecting the pressure of the drill, therefore can't realize permanent the pressure of the drill automatic bit feed, simultaneously drill bit adopts turbobit during horizontal well drilling, it is power that this drill bit adopts mud, mud pressure is larger, and the drill bit drilling speed is higher, otherwise, if drill bit is under pressure larger, drill speed will reduce, and can cause simultaneously the mud pressure in the drilling rod to raise, and therefore permanent pump pressure automatic bit feed is by detecting the mud pressure (being pump pressure) of slush pump in the drilling process, and in conjunction with setting pump pressure, by pid control algorithm, the speed of boring motor is sent in control, realizes permanent pump pressure automatic bit feed.
Permanent moment of torsion automatic bit feed
In drilling process, send brill the pressure of the drill can affect TORQ, send brill the pressure of the drill larger, the TORQ fluctuation is larger, on the contrary fluctuation reduces.In drilling process in order to protect drill bit; improve drilling life of bit; need to reduce the torque ripple on the drill bit; namely reduce the torque ripple of rotating disk; for this problem, permanent moment of torsion automatic bit feed has been proposed, this automatic bit feed is by detecting setting moment of torsion and the actual torque of drilling process turntable (drive on the top); and in conjunction with the pressure of the drill, by the pressure of the drill of PID realization, the automatic bit feed control mode of the two closed-loop controls of moment of torsion.
Referring to Fig. 1, the utility model provides a kind of four permanent automatic bit feed control systems, and this four permanent automatic bit feed control system comprises sending bores controller 6, man machine operation interface 1, the pressure of the drill acquiring unit and send brill frequency converter 7; Man machine operation interface 1, the pressure of the drill acquiring unit and sending bores frequency converter 7 and bores controller 6 and link to each other with sending respectively; The pressure of the drill acquiring unit comprises weight transduser 2, drilling speed sensor 3, pump pressure sensor 4 and rotary table torque sensor 5.
This system reduces hysteresis that the pressure of the drill gathers and the overshoot of system by increase man machine operation interface 1(in original automatic bit feed system), and the suspending weight (the pressure of the drill), drilling speed, pump pressure and rotating disk (drive on the top) moment of torsion that detect in the drilling process by weight transduser 2, drilling speed sensor 3, pump pressure sensor 4 and rotary table torque sensor 5, calculate according to the suspending weight that obtains after testing (the pressure of the drill), drilling speed, pump pressure and rotating disk (drive on the top) torquemeter and reasonably to send drilling speed degree (bore controller 6 and finish by sending); Bore the four permanent automatic bit feed functions (the PID closed-loop control of the pressure of the drill, drilling speed, pump pressure, moment of torsion) that controller 6 controls send brill frequency converter 7 to realize in the drilling process by sending simultaneously.
