Abstract
The invention relates to a signal transmission device comprising a drill pipe or a connecting rod, an insulating layer, a conductive layer and leads. In geological drilling process, a physical detection method is often adopted, an instrument is installed in a drilling tool to carry out measurement while drilling, and then measured signals are transmitted to a ground receiving system and processed so as to truly reflect the situations of drilling process and related stratum change, which relates to the transmission problems of test data or signals. The invention comprises the drill pipe, the insulating layer and the conductive layer, wherein the outer diameter of the drill pipe is sequentially provided with the insulating layer and the conductive layer, and the drill pipe and the conductive layer are respectively connected with the leads; and one end of the drill pipe is provided with a transmission line hole. The invention has simple structure and convenient processing, more excellent transmission effect compared with other signal transmission, stable signals and convenient collection.
Description
Technical field
The invention belongs to the geological prospecting field of test instrument, be specifically related to a kind of signal transmitting apparatus of forming by drilling rod or connecting rod, insulating layer, conductive layer and lead.
Background technology
In the geological drilling process; adopt the method for physical detecting through regular meeting; instrument is packed in the drilling tool; carry out measurement while drilling; again the signal of measuring is transferred to ground receiving system; through handling,, relate to the transmission problem of test data or signal here in the hope of situation in the real reaction drilling process and relevant stratum situation of change.Side signal transmission face in boring has two kinds of methods at present, i.e. wire transmission and wireless transmission, and wire transmission is subjected to the puzzlement of the complicated factors such as specific (special) requirements of drilling process and transfer wire, implements the comparison difficulty; The wire transmission wireless transmission is more likely accomplished relatively, from existing information, transmission of wireless signals has the transmission of mud-pulse signal, it is that electromagnetic wave such as propagates at three kinds of transmission means in the stratum that acoustic signals transmission and electromagnetic wave signal transmit, and the transmission of mud-pulse signal, because signal attenuation speed is difficult to control too soon in the higher and acoustic signals transmission course to the hardware requirement of the quality of mud and transmission, therefore in real work, yet there are no use, the transmission of electromagnetic wave signal is then more actual, the professional and technical personnel knows, the electromagnetic wave signal transmission relies on stratum media to realize in the drilling process of stratum, the signal data process is loaded, make again the signal that is loaded with electromagnetic wave to around emission, finish signal by the tester in aperture and received processing, according to the data introduction is arranged, with drilling rod and drilling rod screwed connection place, through being installed, special the processing make it to have insulation effect, also do not influence its drilling effect, after will insulating in other words two joint drilling rod is considered as two electrodes, finish the transmission of signal, but processing technology and insulation materials treatment process to drilling rod are had relatively high expectations, extremely be difficult for grasping, and signal transmission effect is also undesirable.
Summary of the invention
The signal transmitting apparatus that technical problem solved by the invention provides a kind of simple in structure, signal stabilization, is convenient to gather.
For solving above-mentioned technical problem, the technical scheme that the present invention takes:
Special character of the present invention is: comprise drilling rod, insulating layer, conductive layer, the external diameter of drilling rod sets gradually insulating layer, conductive layer; Described drilling rod is connected with lead respectively with conductive layer; One end of described drilling rod is provided with transmission line hole.
