Description
Technical field
The utility model belongs to Detection Techniques field, oil field, particularly relates to a kind of exploration cable.
Background technology
At present, along with the continuous upgrading of rapid development of science and technology and computer treatmenting information technology, the amount of information that need analyze when oil field geologic is surveyed sharply increases.Require on the one hand that transfer of data demand pairs amount increases in the cable, require data cable to have higher transmission speed and better laser propagation effect on the other hand again, transmit fast and accurately with realization information.And present known comprehensive survey cable generally is the signal cable that utilizes 4 cores or multicore structure, comprises 2 core power lines, and other lines are to then being the holding wire of transfer of data.It is edge core (the being generally 4) strandings that thoroughly do away with more, coats sheath at last and forms.This cable is owing to be subjected to the restriction of structure, want to reach cross-talk effect well, reduce the electromagnetic interference of power line to signal, then power line and holding wire cross section make consistent, simultaneously pitch must do very little, otherwise right two heart yearns of line are in follow-up manufacturing process, relative position very easily is subjected to displacement and changes, and make the cable transmission performance instability, in transmission, produce cross-talk, or impedance is inhomogeneous.In addition, traditional exploration cable is in order to solve cable stretching resistance problem, and cable conductor adopts copper covered steel or alloyed copper conductor, Alloy instead of Copper conductor.Such result is the electric property of having sacrificed cable, has increased transmission attenuation.Have traditional cable to fail to reach the cable block-water effect again, meet the cable aqueous vapor and enter, the institute's number of accepting and believing distortion can't obtain certain result of detection.
Summary of the invention
The utility model provides a kind of exploration cable for solving the problem that prior art exists.
The utility model purpose provides a kind of exploration cable that improves characteristics such as cable electrical performance, transmission performance, mechanical tensile property, block-water performance.
The utility model exploration cable adopts following technical scheme:
A kind of exploration cable comprises conductor and insulating barrier, and conductor has insulating barrier, is characterized in: cable has power line and holding wire; Power line has the extruded polyolefin insulating barrier for the copper conductor of bundle strand; Holding wire is single copper cash, and the extruded polyolefin insulating barrier is arranged outward, to be twisted into line to after, extrude parcel one deck polyolefin jacket again; Cable has external sheath layer.
The utility model exploration cable can also adopt following technical measures:
Described exploration cable is characterized in: cable has strengthening core.Strengthening core is a kind of high young modulus fibers encapsulation one deck polyolefin jacket, can guarantee cable core rounding, tension uniform.
Described exploration cable is characterized in: strengthening core is the fiber that young modulus is higher than 100GPA, is enclosed with one deck polyolefin jacket.High young modulus fiber is adopted in the cable load-bearing, according to the difference of load-bearing pulling force, adopts the fiber of different size, and the load-bearing pulling force is big more, and the red Buddhist nun's number of fiber is high more.
Described exploration cable is characterized in: strengthening core places cable center.
Described exploration cable is characterized in: the space is filled with greasy for preventing water in the cable core.Greasy for preventing water is filled in the space in the cable core, extrudes the pliability height, the strong sheath of tear resistance.Cable blocks water and adopts special formulation to fill greasy for preventing water, guarantees transmission performance to guarantee that cable blocks water.
Described exploration cable is characterized in: power line has two, and holding wire is that 2-8 is right.
Described exploration cable is characterized in: there is tear line the external sheath layer inboard.
Described exploration cable is characterized in: the power line copper conductor is the tin-coated copper conductor.The power line cross-sectional area of conductor is selected different cross sections according to the difference of cable length and system's supply power voltage and line drop.
Described exploration cable is characterized in: holding wire strand pitch is 10.0～19.5mm.Holding wire to can adopt whole parcel form guarantee line between physical dimension, the stability of twisting pitch.
Advantage that the utlity model has and good effect:
Exploration cable adopts the utility model brand-new technology scheme, and holding wire in the cable core pair is split into cable with sub power source line, and the right twisting pitch of holding wire has nothing in common with each other, and takes measures holding wire to Stability Analysis of Structures simultaneously.So electromagnetic interference and holding wire between cross-talk be reduced to minimum.The synchronous signal line is to reach to surpass 5 class network cable specifications to quality requirement, so its electricity function index is stable, reliable.The right characteristic impedance of holding wire remains at 100 ± 15 Ω in 1～100MHz frequency range, signal attenuation is little.Near-end crosstalk attenuation, far-end crosstalk attentuation are little, disturb for a short time, and signal transmission effect is good.Owing to adopted ointment to block water, the cable block-water effect is good, has used strengthening core, and cable load-bearing tensile strength is big, is fit to various occasions and uses.
