Affiliated technical field:
The present invention relates to the down-hole parameter measuring technical field, be specifically related to a kind of down-hole equipment (drill bit) rotating speed measurement method and down-hole tachometric survey pipe nipple.
Background technology:
In order to understand the duty of mining drilling tool (drill bit) in the process of downhole drill, 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.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 drilling tool of down-hole (drill bit) rotating speed 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 safety drilling 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.
Also there is not to provide intuitively, exactly the method and apparatus of drilling tool (drill bit) rotary speed at present.
Summary of the invention:
One of purpose of the present invention is that a kind of down-hole equipment (drill bit) rotating speed measurement method will be provided, two of purpose provides a kind of down-hole tachometric survey pipe nipple of developing according to above-mentioned down-hole equipment (drill bit) rotating speed measurement method, 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: a kind of down-hole equipment (drill bit) rotating speed measurement method, it is upward or on the pipe nipple of the upper and lower rigid connection of tested drilling tool (drill bit) the fluxgate assembly to be set at tested drilling tool (drill bit), utilize the north and south polarity characteristics in big earth's magnetic field, change the circumferential variation magnetic field that records on the fluxgate into the circumferential variation number of times, unit interval inner periphery change frequency is a circumferential variation speed, i.e. the rotating speed of drilling tool (drill bit).
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.
A kind of down-hole equipment (drill bit) tachometric survey pipe nipple, comprise hollow body 1, the two ends of body 1 are provided with internal thread union end 7 and external screw thread union end 5, and the arranged outside of body 1 has or not the outer sleeve 2 of magnetic, are provided with the fluxgate assembly between body 1 and outer sleeve 2.Thereby realize utilizing the fluxgate assembly to carry out the measurement of down-hole equipment rotating speed.
Above-mentioned fluxgate assembly comprises fluxgate 4 and control collection memory module 3.
Above-mentioned body 1 is made by no magnetic material.
The present invention has filled up the blank that drilling tool (drill bit) drilling speed is measured, and can understand the rotating speed of down-hole equipment intuitively, exactly by measuring drilling speed.As everyone knows; drilling tool (drill bit) its rotating speed in normal drilling process is substantially invariable; but in the down-hole equipment of the surface driving of routine or the process of drill bit, run into the situation that bit freezing, bit bouncing etc. influence safety drilling through regular meeting in drilling well; 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, method is simple, 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, 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. to various underground works.The present invention is 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 drilling tool orientation in the industry in probing was measured in the past, in the present invention it was applied in the kinetic measurement of rotating speed of drilling tool.In the enforcement it is arranged on the last or tested drilling tool (drill bit) of any conventional drilling tool (drill bit) up and down, can realizes measuring 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.
