【発明の詳細な説明】 ｒ の振作データの音響式伝送方法 本発明は、坑井の掘削データを坑底から地表に伝送する方法に係わり、特にその ような方法で、坑底と地表とを結ぶ二つの並列伝送チャネルを用いる方法に係わ る。[Detailed description of the invention] Acoustic transmission method of vibration data of r The present invention relates to a method of transmitting well drilling data from the bottom of a well to the surface of the earth, and in particular, This method involves the use of two parallel transmission channels connecting the bottom of the mine and the surface. Ru.
坑井、即ち例えば油井を掘削する際、掘削パラメータをより良く制御するために は掘削作業を指揮する者が坑底に存在する諸条件（偏向要因、ビット回転速度、 ビットに掛かる重量、ビットのトルク、温度、加速度等）を認識することが望ま しい、この条件認識はリアルタイムに行なわれることが好ましく、そのために坑 底から地表にデータを伝送する手段が必要となる。In order to better control the drilling parameters when drilling wells, i.e. oil wells, for example. means that the person directing the drilling operation should check the conditions existing at the bottom of the hole (deflection factors, bit rotation speed, It is desirable to recognize the weight on the bit, bit torque, temperature, acceleration, etc.) This condition recognition is preferably done in real time, so A means of transmitting data from the bottom to the surface is needed.
坑底の諸条件を認識することによって、掘削をより迅速に、かつより低コストで 行なうことができる。そのうえ、掘削指揮者が、例えば岩石の種層の変化やビッ トの摩耗といった任意の条件変化に敏速に対応することも可能となる６坑底から 地表へのデータ伝送を実現する手段はこれまでに幾つか提案されている。それら の手段の中に、導電体による伝送、及び音波または電磁波による伝送が有る。ま た、掘削泥水中の圧力波によるデータ伝送も既に提案されている。このシステム では、バイブストリングに沿って移動する泥水の圧力が、例えばバイアストリン グのビットに近接する箇所に配置されたサブアセンブリ内に取り付けられたサー ボバルブを介して変更される。Awareness of bottomhole conditions allows for faster and less costly drilling. can be done. Moreover, the drilling director may be able to detect, for example, changes in the rock seed layer, 6. From the bottom of the hole, it is possible to quickly respond to arbitrary changes in conditions such as wear on the bottom of the hole. Several means for realizing data transmission to the earth's surface have been proposed so far. those Among these methods, there are transmission by electrical conductors and transmission by sound waves or electromagnetic waves. Ma Data transmission using pressure waves in drilling mud has also been proposed. this system In this example, the pressure of muddy water moving along the vibe string is A service installed in a subassembly located close to the bit of the plug. Modified via Bobalve.
このようなシステムの信号伝送速度はさほど大きくなく、圧力波は約１５００ｍ ／ｓでしか伝播しない。坑底と地表との間での波の減衰と、泥水の圧力変更に内 在する限界と、地表でデータの品質を維持する必要性とを勘案して、データの速 度は低く維持される。The signal transmission speed of such a system is not very high, and the pressure wave is about 1500 m. It propagates only at /s. This is due to the attenuation of waves between the bottom of the mine and the surface, and the change in pressure of muddy water. The speed of data should be The temperature is kept low.
本発明は、掘削泥水中の圧力波によるデータ伝送の欠点を、単純でかつ信頼性の 向上したデータ伝送方法の提供によって克服することを目的とする。The present invention overcomes the drawbacks of data transmission by pressure waves in drilling mud in a simple and reliable manner. The objective is to overcome this by providing improved data transmission methods.
上記目的達成のために、本発明は、坑井の掘削条件に関するデータを坑底から地 表に伝送する方法であって、−掘削泥水の坑井内への進入口において掘削泥水の 圧力を連続的に測定する作業と、 ・−坑底において少なくとも一つの作業条件をセンサで測定する作業と、 一伝送を、前記センサでの測定の結果に則して符号化して掘削泥水中に発生され るパルスの形態で実現する作業と、−掘削泥水中のパルスを掘削泥水の坑井内へ の進入口における圧力測定によって検出する作業と を含み、 掘削泥水中のパルスによって惹起されるバイブストリングの振動を同時に検出す る付加的作業を含むことを特徴とする データ伝送方法を提供する。In order to achieve the above object, the present invention transmits data regarding the drilling conditions of a well from the bottom of the well to the ground. A method for transmitting drilling mud into a wellbore at an entrance of the drilling mud into the wellbore. Continuously measuring pressure; - Measuring at least one working condition at the bottom of the mine with a sensor; A transmission is encoded according to the measurement result of the sensor and generated in the drilling mud. - Pulses in the drilling mud into the wellbore of the drilling mud.

本発明の他の特徴及び利点は、添付図面を参照しての以下の説明分読めば明らか となってこよう。添付図面の第１図は掘削アセンブリの概略的断面図であり、第 ２図は処理回路の概略的説明図である。Other features and advantages of the invention will become apparent from the following description with reference to the accompanying drawings. Let's come. Figure 1 of the accompanying drawings is a schematic cross-sectional view of the drilling assembly; FIG. 2 is a schematic explanatory diagram of the processing circuit.
第１図に示した掘削アセンブリはマスト１０を含み、マスト１０がそれ自体公知 であるように具備したフック１２には、その全体に符号１４を付して示したバイ ブストリングが吊下されている。バイブストリング１４は１個のドリルとット１ ６と、複数のドリルカラー１８と、複数のドリルバイブ２０とを含む０図示例で は、バイブストリング１４はロータリーテーブル２２によってか、または“パワ ースイベル”と呼称されるモータ駆動式のヘッドによって回転される。加圧され た掘削泥水はホース２４を通って供給源（図示せず）からバイブ２０内部に達す る。この泥水は管２６を経て循環し、貯蔵タンク（図示せず）に戻る。ビット１ ６近傍に配置されたサブアセンブリ２日内に取り付けられたサーボバルブが、加 圧泥水中に圧力波を発生するべく該泥水の流れを選択的に中断するのに用いられ る。坑底で得られた測定値を表わす圧力波を泥水中に公知のように発生し得るサ ブアセンブリ２８は、測定装置及び制御装置を具備している。上記圧力波は地表 において、ホース２４に取り付けられた圧力センサ３２によって検出される。The excavation assembly shown in FIG. 1 includes a mast 10, which is known per se. The hook 12 equipped with Brass strings are hanging. Vibrator string 14 includes 1 drill bit 1 6, a plurality of drill collars 18, and a plurality of drill vibes 20. The vibe string 14 is connected to the rotary table 22 or - rotated by a motor-driven head called a ``swivel''. The drilling mud reaches the inside of the vibrator 20 from a supply source (not shown) through a hose 24. Ru. This slurry is circulated through pipe 26 and returned to a storage tank (not shown). Bit 1 6. A servo valve installed within 2 days of the subassembly located near the Used to selectively interrupt the flow of muddy water to generate pressure waves in the muddy water. Ru. A pressure wave representative of the measurements taken at the bottom of the well can be generated in muddy water in a known manner. The tube assembly 28 is equipped with measuring and control equipment. The above pressure wave is on the ground surface. is detected by a pressure sensor 32 attached to the hose 24.
泥水中に発生された圧力波はバイブストリング１４に、対応する振動をも生じさ せる。本発明によって、バイブストリングに第二のセンサを取り付ければデータ をより良く読み取れることが判明した。The pressure waves generated in the muddy water also cause corresponding vibrations in the vibe string 14. let According to the present invention, if a second sensor is attached to the vibe string, the data can be It turns out that it can be read better.
第１図に示したように、掘削アセンブリはバイブストリング１４上端に取り付け られた加速度計３４も含み、この加速度計３４はバイブ２０の長手方向加速度の 測定に用いられる。As shown in FIG. 1, the digging assembly is attached to the upper end of the vibe string 14. The accelerometer 34 also includes an accelerometer 34 that measures the longitudinal acceleration of the vibrator 20. Used for measurement.
第２図に、センサ３２及び加速度計３４によって発せられた信号を処理する回路 を概略的に示す。FIG. 2 shows a circuit for processing the signals emitted by sensor 32 and accelerometer 34. is schematically shown.
バイブストリング１４上端に配置された軸線方向張力（もしくは歪み）計を加速 度計３４に替えて、または付加的なデータを得るべく用いることも可能である。Accelerate the axial tension (or strain) meter placed at the upper end of the vibe string 14 It can also be used in place of the meter 34 or to obtain additional data.
後者の場合、付加した計器によってもたらされるデータは、寄生雑音の影響を一 層低減するうえで有用である。このデータは第２図に示した並列チャネルによっ て処理される。In the latter case, the data provided by the attached instrumentation is free from parasitic noise effects. This is useful for reducing layers. This data is transmitted through the parallel channels shown in Figure 2. will be processed.
寄生雑音の影響を最小限とするために、例えばバイブストリングの上端の半径方 向加速度を検出するような他の計器を付加することも可能であろう。To minimize the effects of parasitic noise, for example, It would also be possible to add other instruments such as detecting directional acceleration.
いずれの場合も、様々なセンサによって発せられた信号は第２区の回路で処理さ れる。波の、パイプストリング材中を伝播する速度は掘削泥水中を伝播する速度 の３倍以上であるので、処理回路は信号を、タイミングを取って再配列できなけ ればならない。In both cases, the signals emitted by the various sensors are processed in the second district circuit. It will be done. The speed at which waves propagate through the pipe string material is the speed at which they propagate through drilling mud. , so the processing circuit must be able to rearrange the signals in a timely manner. Must be.
この再配列は、信号同士の相関によって行なっても、また二つの媒質中ての速度 に関する知識に基づいて行なってしい。例えば地表クロンク分参照して各データ チャネルに間して確立された品質指数が適用される。このことは個々の重みを各 データチャネルに割り当てることを可能にし、その結果一方のチャネルが放棄さ れ得る。総合的な品質指数は、別個に復号された信号同士の非コヒーレンスから 算出することも可能である６ そのうえ、データチャネルを再配列しながら同時に寄生地表信号、特にポンプに 起因する雑音の変位を実現することが可能である。上記寄生雑音は次に、加重平 均がめられることによって減少する。This rearrangement can be done by correlation between signals, or by changing the velocity in the two media. Do this based on your knowledge of For example, each data by referring to the ground surface Kronk The quality index established for the channel is applied. This means that the individual weights data channel, resulting in one channel being relinquished. It can be done. The overall quality index is determined by the noncoherence between separately decoded signals. It is also possible to calculate6 Moreover, while reordering the data channels, at the same time the parasitic surface signals, especially the pumps, It is possible to realize a displacement of the resulting noise. The above parasitic noise is then Decreased by being evened out.
