Description

The measuring method and the pipe nipple of down-hole equipment (drill bit) rotary speed and direction
Affiliated technical field:
The present invention relates to the down-hole parameter measuring technical field, be specifically related to the measuring method and the pipe nipple of a kind of down-hole equipment (drill bit) rotary speed and direction.
Background technology:
In order to understand the duty of mining drilling tool (drill bit) in the downhole drill process, need to be grasped the various parameters of down-hole equipment (drill bit) operation.In these parameters, rotating speed is one of them significant data.In order to obtain parameter accurately, the method that is adopted was in the past: the rotating speed of being estimated down-hole equipment (drill bit) by the rotating speed of aboveground drilling tool, the method that does not also have direct energy measurement down-hole equipment (drill bit) rotating speed at present, estimate that by the rotating speed of aboveground drilling tool the problem that this method of rotating speed of down-hole equipment (drill bit) exists is not have accuracy, because having no rigidity in the process that creep into the down-hole, the drilling rod of last km can say that aboveground drilling tool rotating speed is not being represented the rotating speed of down-hole equipment (drill bit).And under the situation of drilling tool (drill bit) drilling well of adopting Luo bar pump, aboveground drilling rod is motionless, and the rotating speed of the down-hole equipment of down-hole (drill bit) then can't be estimated.
Drilling tool (drill bit) is important as parameters such as down-hole pressure, temperature, moment of torsion, axle power at the downhole drill rotating speed, it is extremely important to guaranteeing drilling safety to obtain these parameters, also is an indispensable information to the failure analysis of drill bit, the aspects such as optimal design of drill bit in addition.At present and in the future extended reach well and horizontal well are the trend of drilling well industry, and increasing along with extended reach well and horizontal well adopts the situation of Luo bar pump drill well also more and more, and not having drilling tool (drill bit) is inconceivable thing in the tachometric survey of downhole drill.
Because the particularity of downhole operations, the rotation direction of drilling tool (drill bit) also is one and does not allow wield parameter, drilling tool (drill bit) generally is that folk prescription rotates to constant speed under the situation that drilling tool (drill bit) normally creeps into, when situations such as down-hole generation chance card, bit bouncing, the rotating speed of drilling tool (drill bit) will change even reverse.Rotating speed and orientation measurement by drilling tool (drill bit) can in time be understood down-hole information, make the technician in time take Corresponding Countermeasures to guarantee the safety of normal drilling well and wellbore construction.Because the mining site drilling well is oil drilling cost height particularly, so the lay special stress on safety.If untimely accurate understanding down-hole information can cause catastrophic consequence.The producer as drilling tool and drill bit knows their failure reasons and mechanism by understanding down-hole equipment and drill speed in addition, can optimize their design and fabrication scheme thus.
Also there are not to provide intuitively, exactly the measuring method and the equipment of drilling tool (drill bit) rotary speed, direction at present.
Summary of the invention:
One of purpose of the present invention is the measuring method that a kind of down-hole equipment (drill bit) rotary speed and direction will be provided, two of purpose provides a kind of pipe nipple of developing according to the measuring method of above-mentioned down-hole equipment (drill bit) rotary speed and direction, to overcome the problem non-directly perceived, inaccurate that prior art exists.
For overcoming the problem that prior art exists, technical scheme provided by the invention is: the measuring method of a kind of down-hole equipment (drill bit) rotary speed and direction, it is on tested drilling tool (drill bit) or on the tested drilling tool (drill bit), two groups of fluxgate assemblies are set on the pipe nipple of following rigid connection, two groups of fluxgate assemblies lay respectively at disalignment in the 90 degree radian zones of the surfaces of revolution on vertical line, the circumferential variation number of times is changed in the circumferential variation magnetic field that records on the fluxgate into, unit interval inner periphery change frequency is a circumferential variation speed, just the rotary speed of drilling tool (drill bit); The signal that while two groups of fluxgate assemblies send has phase difference, utilizes phase difference can judge the rotation order of two groups of fluxgate assemblies, also just can determine rotation direction.
Above-mentioned fluxgate assembly is arranged in the outer sleeve of drilling tool (drill bit) or pipe nipple usually.Identical with the set-up mode of other conventional assembly, can be provided with as long as have living space.
The measurement pipe nipple of a kind of down-hole equipment (drill bit) rotary speed and direction, comprise hollow body 3, the two ends of body 3 are provided with internal thread union end 1 and external screw thread union end 6, the arranged outside of body 3 has or not the outer sleeve 2 of magnetic, be provided with two groups of fluxgate assemblies (4) and fluxgate assembly (5) between body 3 and outer sleeve 2, these two groups of fluxgate assemblies (4) and fluxgate assembly (5) lay respectively at disalignment in the 90 degree radian zones of the surfaces of revolution on vertical line.Thereby realize utilizing fluxgate to carry out the measurement of down-hole equipment (drill bit) rotary speed and direction.
Above-mentioned fluxgate assembly (4) and fluxgate assembly (5) comprise fluxgate and control collection memory module respectively.
Above-mentioned body 3 is made by no magnetic material.
The present invention has filled up the blank of drilling tool (drill bit) rotary speed and orientation measurement, can understand the rotating speed and the direction of down-hole equipment (drill bit) intuitively, exactly.As everyone knows; drilling tool (drill bit) its rotating speed and direction of rotation in normal drilling process are substantially invariable; but in the process of down-hole equipment (drill bit) in drilling well of the surface driving of routine, run into the situation that bit freezing, bit bouncing etc. influence safety drilling through regular meeting; in the drilling process that Luo bar pump drives; the normal drilling well of down-hole equipment (drill bit) is because the variation of drive unit fault or geological condition also can be damaged, and drilling tool (drill bit) rotating speed is the major parameter that can directly reflect drilling well working condition quality.
Advantage of the present invention is:
1, cost is low: make full use of natural magnetic energy and measure rotating speed, it is low to measure cost.
2, applied widely: as to measure applicable to drilling tool rotating speed to various underground works, can understand underground work information indirectly by drilling tool (drill bit) rotating speed, as the damage of drilling tool (drill bit), the variation of geological stratification etc., be particularly useful for the measurement of drilling tool (drill bit) drilling speed of Luo bar pump.
3, simple in structure: the inventive method is implemented easily, the fluxgate assembly that this method adopted is a kind of equipment commonly used, the static parameter that often was used to carry out the orientation of drilling tool in the industry in probing was measured in the past, in the present invention it is applied in the kinetic measurement of rotating speed of drilling tool, it is arranged on any conventional drilling tool (drill bit) is gone up or tested drilling tool (drill bit) all can be realized measuring up and down by method of the present invention.For the enforcement that illustrates further the inventive method is easy, also provide a kind of simple in structure especially in concrete configuration aspects the present invention, make the pipe nipple of processing easily.
4, safe: because simple in structure, implementing does not influence the safety of other drilling tool drilling wells easily.
