Summary of the invention: the utility model is primarily aimed at the shortcoming of prior art, adopts the on-the-spot mode that detects of portable instrument, has designed a kind of column cable handheld terminal detector of checking the communication condition between column cable and the underground survey assembly at situ of drilling well.
The utility model is achieved in that the utility model comprises detector and test cable, it is characterized in that: described detector is made of handheld terminal detector 7, one end of test cable 6 connects handheld terminal detector 7, and the other end connects the cable female joint in the well head tool joint;
The end that described test cable 6 connects handheld terminal detector 7 can be USB interface, perhaps com interface;
Described test cable 6 one ends are connected with the female joint of drilling rod inner cable by quick-speed plug butt joint male;
Described test cable 6 internal layers are single core copper cash, outsourcing one deck plastic sheath and steel wire cover;
Described handheld terminal detector 7 adopts dry cell power supplies or is its power supply by charger;
Described handheld terminal detector 7 has LCDs, is used to show the data of underground survey assembly;
The LCDs of described handheld terminal detector 7 can be checked all data of measuring assembly by last downturning key.
When implementing test at the scene, one end of test cable 6 is connected with cable female joint in being arranged on tool joint by quick-speed plug butt joint male, the other end is connected with handheld terminal detector 7 by USB or com interface, and whether the segmentation tie cable and the communication between the underground survey assembly that can realize detecting the down-hole be normal; If communication is just often, will show on handheld terminal detector 7 LCDs and measure the data that assembly measures, these data comprise hole deviation, orientation, tool face azimuth, weight component and gravity and, magnetic-field component and magnetic field and, data such as temperature, vibration; When if communication is undesired, then free of data shows, if when measuring the part or all of sensor of the measurement inserting tube of assembly and damaging, data presented will be incorrect.
Whether the beneficial effects of the utility model: it is normal to detect between column communication cable and the underground survey assembly communication in real time if being.Because communication cable is a multistage, every section by the butt joint of rapid abutting joint head, behind the drill string that whenever is lowered to a post or a few post prepackage communication cable, promptly detect with the utility model, if handheld terminal detector 7 shows normal data, prove that measurement assembly to the communication of the multistage communication cable at this place normally can continue to bore down; And if handheld terminal detector 7 not the undesired measurement inserting tube that promptly will consider to measure assembly of video data or video data damaged or just to have gone between several sections communication cables of well communication undesired, change after can investigating out problematic multistage cable rapidly.
Description of drawings:
Fig. 1 is the syndeton schematic diagram of the utility model and down-hole pipe string.
The specific embodiment:
Implement 1:
Below in conjunction with Fig. 1 the utility model is further specified: when boring down, to measure assembly 1 earlier and be lowered to non-magnetic drilling tool 2, begin then to bore for 3 times with column, in every root post 3 communication cable 4 is set, and holder hangs over the drilling tool inwall, cable between every root post 3 is connected by the butt joint 5 that is provided with, in being lowered to the process of drilling tool, whenever after being lowered to one or a few drill string, just the quick-speed plug of test cable 6 one ends butt joint male is connected with cable female joint in the drilling rod in the top, the other end of test cable 6 is connected with handheld terminal detector 7 by USB, also can be com interface; Connect the back that finishes the connection of G.I.H is detected,, prove that to measure assembly normal to the multistage cable communication at this place, brill under just can continuing if handheld terminal detector 7 shows normal data; If handheld terminal detector 7 not video data or video data is undesired, will consider that measurement while drilling exploring tube damages, or it is undesired just to have gone between several sections communication cables 4 of well communication; So circulation stops to bore down when installing electromagnetic wave emission assembly additional down to needs, detects once more, detect normal after, again with the butt joint of the communication cable in last root drill string female with after electromagnetic wave emission assembly docks under be drilled into the shaft bottom and creep into.
