Description
Affiliated technical field:
The present invention relates to the down-hole and use 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 and use 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 was in the past adopted is: 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, increasing along with extended reach well and horizontal well, and the situation of employing Luo bar pump drill well also gets 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 the object of the 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 of developing according to above-mentioned down-hole equipment (drill bit) rotating speed measurement method and uses pipe nipple, 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), utilizes the north and south polarity characteristics in big earth's magnetic field, changes 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.
Pipe nipple is used in a kind of down-hole equipment (drill bit) tachometric survey; 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, between body 1 and outer sleeve 2, is provided with the fluxgate assembly.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 processed 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 through 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: the drilling tool rotating speed applicable to various underground works is measured, and can understand underground work information indirectly through drilling tool (drill bit) rotating speed, like the damage of drilling tool (drill bit), the variation of geological stratification etc.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 is in the past measured, and in the present invention it is applied in the kinetic measurement of rotating speed of drilling tool.In the enforcement it is arranged on any conventional drilling tool (drill bit) and goes up perhaps tested drilling tool (drill bit) up and down, can realize measuring through 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 structure aspects the present invention, the pipe nipple of easy manufacture and processing.
4, safe: because simple in structure, implementing does not influence the safety of other drilling tool drilling wells easily.
