Description
The intelligence probing monitoring instrument that drilling intelligent controller of the present invention relates to geology core drilling measurement class belongs to modern technical field of measurement and test.
In geological drilling, to operating mode in rock variation, the hole and drilling accident forecast, be to drill the anxious to be solved and unsolved a great problem in boundary for a long time both at home and abroad, the Unpredictability of probing situation, make the decision-making of selection of probing parameter and drilling process exist very big blindness, this is even more serious when looking for ore deposit, deep and blind ore, various brills in probing is produced are joined instrument at present, comprise and creep into the Computerized multifunctional monitoring system, owing to all be the type of alarm of isolatedly individual data being taked to establish upper and lower limit; Do not possess the ability of influencing each other of multi-parameter being carried out comprehensive analysis processing, thereby the little burning of the burning of bits, drill bit, breaking of rod bar, drillability variation, catalase, the core that take place in can't producing probing are stifled etc. accurately shows or forecast.Work efficiency is carried not high, serious waste phenomenon.
The objective of the invention is to propose a kind ofly can implement monitoring at any time, correct judge, and optimize the drilling intelligent controller of drilling process the probing situation
Drilling intelligent controller of the present invention is partly combined by host hardware apparatus system and computer software programs two, with the supporting use of rig.
Drilling intelligent controller of the present invention is to adopt modern measuring technology, on the basis of data processing technique and computer technology, taken into full account and brought into play operating personnel's subjective initiative, people's the discriminatory analysis method of effectively creeping into particularly, and the modern probing of absorption new method, set up different judgment model samples, supply contrast, analysis and judgement, realized that multi-parameter weighs for the operator from motion tracking, comprehensive judgement, man-machine combination with priority treatment the best carries into execution a plan.Broken generally adopt in the past parameter is only established the type of alarm of upper and lower limit or isolated the pattern that shows side by side in fact.Really realized drilling accident is effectively reported to the police, and taked corresponding measure, can compare, analyze by the software program and the various different mode of compilation simultaneously, thereby accurately judged operating mode in rock variation and the hole according to the accident prediction situation.
Above-mentioned design philosophy has embodied the principle of artificial intelligence, and artificial intelligence is actual to be the effective analysis and judgement method of drawing and imitating the experience driller, adopts mode identification technology, and the self study technology realizes real-time monitoring and optimal control in the hole.So-called pattern sample has two types: a class is on the sampling basis, set up sample by automatic identification and study, then to later parameter sampling, by feature extraction, compare with sample characteristics, and carry out the comprehensive judgement of different mode, and reach a conclusion at last and export, differentiate simultaneously whether the sample condition changes, as changing, then need rebulid sample, second class is gone down in circulation and so forth, sample is fixed, adorning different samples for extraction in the sample storehouse, direct and random acquisition sample compares and judges, identification output at last., in the second class judgment mode, there are two to judge that subpattern need particularly point out, be illustrated:
(1) judge the catalase pattern, i.e. determining of catalase COEFFICIENT K a:
Wherein: A: represent the load current instantaneous value;
N: represent the instantaneous value number:
Km: represent the catalase dividing value:
This judgment model promptly has driller's rich experiences, and the variation system concept in the modern mathematic statistics is arranged again, makes that like this driller's experience is further scientific.
(2) rock drillability index Kz:
Wherein: V: represent drilling speed; N: represent rotating speed; Pm: represent the pressure of the drill; Kz: be the revolution approach under unit the pressure of the drill, it to same drill bit is the adaptive situation parameter that can reflect drillability of rock size and drill bit and institute's rock drilling in certain the pressure of the drill scope.
Can eliminate automatically with the self study recognition technology in the Artificial Intelligence in addition and creep into when the falling the bar issuable error of drilling depth that adds up.Equally with similar approach can eliminate creep in movable once in a while drilling tool and the drilling depth error that adds up that causes.The thought of--artificial intelligence+modern times probing theoretical--monitoring optimizing control in real time that facts have proved data acquisition is novel, correct, and it all is very high to the monitoring of operating mode in the hole and the accuracy and the reliability of judgement.
In order to bring into play driller's subjective initiative, also designed five manual intervention keys in this system, some MICROCOMPUTER PROCESSING difficulty and artificial treatment be problem easily, establishes that manual intervention is strong to be handled by the people; Some decision-makings important or crux, computer can be by oneself, but weigh for operating personnel with priority treatment, and people, machine combination can reach optimum efficiency like this.
For example: the necessary condition of correctly weighing is that drilling tool is in equilibrium state, and it is zero that upper cylinder half is pressed, and adds recirculated water, drilling tool revolution, whether this is system's identification easily, but lift from the bottom of the hole not easy to identify to drilling tool, and the people is easy to identification, establishing the intervention of weighing and being good for by operating personnel's differentiation, assert.Frequently fall the caused error of putting forward of bar for another example, can eliminate automatically by artificial intelligence, but distinguish is normally to creep into, still be guard aperture, cleaning bottom of hole, sweep residual core, when promptly whether should remember chi into this moment, system just is difficult for correct decision, and operating personnel differentiate easily, and the drilling depth intervention is strong to be differentiated and correct the processing by operating personnel so establish.In sum, man-machine combination, but not only simplified design, save memory, also can improve the adaptive capacity of system, expanded functionality improves the ability of dealing with complex situations.
