Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment one:
With reference to accompanying drawing 1, intelligent composite continuous-tube of the present invention, comprise interior pipe pressure bearing and seal layer 1, resin fibre enhancement layer 2, external protection 3, power line 4 and optical fiber data line 5, interior pipe pressure bearing and seal layer 1, resin fibre enhancement layer 2 and external protection 3 are whole coiled tubing, power line 4 and optical fiber data line 5 are whole line, the outside of interior pipe pressure bearing and seal layer 1 is wound around and is woven with resin fibre enhancement layer 2, the outside of resin fibre enhancement layer 2 is coated with external protection 3, power line 4 has been imbedded in the inside of external protection 3, optical fiber data line 5 has been imbedded in the inside of external protection 3.Interior pipe pressure bearing and seal layer 1 adopts PVDF or crosslinked polyethylene; there is the characteristic of antigen oleic acid caustic corrosion characteristic; resin fibre enhancement layer 2 is thermoplasticity or thermoset resin fibres enhancement layer, and external protection 3 adopts thermoplastic resin system PVDF or the crosslinked polyethylene with antigen oleic acid caustic corrosion characteristic.Power line 4 is formed by copper wire woven, and power line 4 can by the wax deposition of heating removing intelligent composite continuous-tube inside, and power line 4 is at least 3.
Enter plunger displacement pump under utilizing intelligent composite continuous-tube, optical fiber data line 5 adopts a root multimode fiber data wire and a single-mode fiber data wire.Power line 4 and optical fiber data line 5 are evenly distributed on the inside of external protection 3.
Multimode fibre data wire can detect the temperature at whole continuous-tube diverse location place by continuous uniform, the i.e. Temperature Distribution of whole pit shaft, by the analysis to variations in temperature, can judge whether wax deposition occurs in pipe, wax deposition region and position range, occur if any wax deposition situation, ground control system can start electrical heating paraffin removal program automatically, paraffin removal heating utilizes the power line 4 being embedded in the inside of external protection 3, it is made to generate heat by certain electric current, it is then realized by multimode fibre data wire that heating temp controls, namely the temperature constant in wax deposition region is maintained, after certain hour, paraffin removal terminates, again oil extraction operation is recovered.
Compare with multimode fibre data wire, single-mode fiber data wire then directly can measure the pressure and temperature of liquid level residing for plunger displacement pump, according to the liquid-level pressure situation that single-mode fiber data wire is measured, ground control system regulates down-hole linear motor automatically, the i.e. operating frequency (jig frequency) of down-hole plunger displacement pump, formation fluid production and Discharge rate is made to keep balancing, reach efficient energy-saving and intelligent target of recovering the oil, but single-mode fiber data wire can only measure the pressure and temperature of a point, multimode fibre data then evenly can measure the temperature of whole pit shaft.
Embodiment two:
With reference to accompanying drawing 2, with the optical fiber data line 5 unlike: intelligent composite continuous-tube of embodiment one imbed inner in pipe pressure bearing and seal layer 1; Optical fiber data line 5 is single-mode fiber data wire, enters drill bit Bottom Hole Assembly (BHA) under utilizing intelligent composite continuous-tube of the present invention, and Bottom Hole Assembly (BHA) comprises temperature, pressure sensor and can measure hole deviation, azimuthal measurement-while-drilling system.
The single-mode fiber data wire at one end temperature pick up of connecting downhole, pressure sensor, MWD(wireless drilling is measured) instrument or the well logging of LWD(wireless drilling) instrument, the other end connects geoceiver, thus obtains downhole temperature, pressure, stratum gamma resistivity information in real time.
According to the explanation of above-described embodiment, in actual applications, make different specific embodiments according to different real requirements.
According to the difference of transfer point modulus, optical fiber can be divided into single-mode fiber and multimode fibre.So-called " mould " refers to the light beam entering optical fiber with a fixed angular speed.Single-mode fiber adopts solid state laser to do light source, and multimode fibre then adopts light emitting diode to do light source.Multimode fibre allows multi-beam to propagate in a fiber simultaneously, thus forms mould dispersion because each " mould " light enter the angle of optical fiber different they to arrive time of another end points also different, this feature is called that mould disperses.Mould dispersion technology limits the bandwidth sum distance of multimode fibre, and therefore, the heart yearn of multimode fibre is thick, and transmission speed is low, apart from short, overall transmission performance is poor, but its cost compare is low, under being generally used for the environment that building is interior or geographical position is adjacent.Single-mode fiber can only allow light beam to propagate, so single-mode fiber does not have mould dispersing characteristic, thus, the fibre core of single-mode fiber is corresponding comparatively thin, and transmission frequency bandwidth, capacity are large, and transmission range is long, but needs lasing light emitter because of it, and cost is higher.The fibre core of single-mode fiber is comparatively thin, enables light be transmitted directly to center, is suitable for adopting when distance is longer.In addition, the range loss of single mode signal is less than multimode.Under the distance of 3000 feet, 50% of its LED light signal intensity of multimode fibre possible loss, and single mode only loses 6.25% of its laser signal under same distance.Single-mode fiber only has single propagation path, is generally used for long range propagation, and multimode fibre has multiple propagation path, and the bandwidth of multimode fibre is 50MHz ~ 500MHz/Km, and the bandwidth of single-mode fiber is 2000MHz/Km.
Distribution type fiber-optic temperature-sensitive technology be development in recent years get up a kind of in real time, the temperature sensor technology of online, multiple spot, can be used for real-time measuring tempeature field.In distributed optical fiber temperature sensing system, optical fiber is sensor and signal transmission passage, system utilizes space temperature field residing for optical fiber to investigate to the scattered light signal backward in optical fiber, then is shown in real time by temperature information through signal conciliation, acquisition and processing.In time, utilizing the time difference of the transmission speed of light wave in optical fiber and backward optical echo, in conjunction with OTDR(optical time domain reflectometer) technology accurately locates measured temperature point.Not charged, the anti-radio frequency of detection fiber in distribution type fiber-optic temperature-sensitive system and electromagnetic interference, anti-flaming, explosion-proof, anticorrosive, high pressure resistant and strong-electromagnetic field, resistance to ionising radiation, can safe operation in harmful environment, under the adverse circumstances such as a lot of high temperature, high heat, there is peculiar advantage.
The mechanism of optical fiber temperature-measurement is according to backward Raman (Raman) scattering effect.Laser pulse and optical fiber interaction of molecules, scattering occurs, and scattering has multiple, as Rayleigh (Rayleigh) scattering, Brillouin's (Brillouin) scattering and Raman (Raman) scattering etc.Wherein Raman scattering is the thermal vibration due to optical fiber molecule, and it can produce a light longer than optical source wavelength, claims Stokes (Stokes) light, and the light that one shorter than optical source wavelength, is called anti-Stokes (Anti-Stokes) light.Optical fiber makes the anti-Stokes in optical fiber (Anti-Stokes) light intensity change by the modulation of external temperature, the ratio of Anti-Stokes and Stokes provides the absolute instruction of temperature, utilizes this principle can realize the distributed measurement along fiber optic temperature field.In conjunction with light-pulse generator and the Signal acquiring and processing technology at a high speed of high-quality, just can obtain along optical fiber accurate temperature value a little.The laser pulse that system postpones with a 10ns, can realize the temperature survey of the optical fiber space resolution ratio 1m to maximum 30km, namely be equivalent to 30,000 survey mark.Based on principle above, distributed optical fiber temperature measurement technology is particularly suitable for circuit and crosses thermal measurement and fire alarm.
Multimode fibre data wire can detect the temperature at whole intelligent composite continuous-tube diverse location place by continuous uniform.Multimode fibre data wire can by detecting and then realizing judging whether the inside of intelligent composite continuous-tube wax deposition phenomenon occurs in real time.Power line can by the wax deposition of heating removing intelligent composite continuous-tube inside.
Because the transmission range of single-mode fiber is far away, generally be applied in field of telecommunications, single-mode fiber data wire is imbedded in continuous-tube, enter to recover the oil under adopting intelligent composite continuous-tube of the present invention the Bottom Hole Assembly (BHA) of the electric submersible pump in field, plunger displacement pump or drilling applications, temperature pick up, pressure sensor, MWD or LWD of single-mode fiber data wire at one end connecting downhole, the other end connects geoceiver, thus obtains downhole temperature, pressure, stratum gamma resistivity information in real time.
