Description
Technical field:
The utility model relates to a kind of flow testing system that is used for the particularly elevated temperature heat oil recovery of oil field oil, gas well, gas well.
Background technology:
At present, based on production logging and the oil-gas reservoir Dynamic Monitoring of testing is that the oil-gas reservoir exploitation provides reliable data, but these two kinds of methods all are to produce needs according to the oil gas well to carry out the routine test operation, measuring intervals of TIME is big, can not guarantee that the time of measuring is exactly the best opportunity that diagnosis production problem and oil-gas reservoir change, thereby dynamic change characterization that can't accurate description oil-gas reservoir.In addition, in the production logging of oil gas well, test process, owing to be subjected to the influence of factors such as down-hole casing breakage, pickup, downhole instrument often is hampered, and causes some producing wells can not proper testing; Complicated well of other such as horizontal well etc. can't carry out the production fluid amount monitoring of each layer position in the normal well.Simultaneously, the test of production fluid is based on current collecting umbrella formula turbine measuring technique in the conventional well, the sensitivity of turbine self since in the high temperature well character of liquid stream be viscous crude and influenced, magnet at high temperature performance is no longer stable, also will cause measuring inaccurate, and test technology complexity, fault rate height, testing expense is higher, is difficult to general implementation.
The utility model content:
The purpose of this utility model is to provide a kind of permanent high-temperature oil gas producing well optical fiber flow testing system of can be permanent oil reservoir dynamically being monitored in real time and can monitor in real time horizontal well.
The utility model is to realize like this.This kind test macro is made up of ground light source and demodulating system, ground sound wave emissions system, terrestrial transmission optical cable, down-hole high temperature resistant and high-pressure resistant optical cable, down-hole sonic generator, single-mode fiber, downhole optic fiber flow transmitter, in ground light source and demodulating system, ground sound wave emissions system are arranged between oil well control; The terrestrial transmission optical cable is connected with the down-hole high temperature resistant and high-pressure resistant optical cable by oil, gas well mouth blowout prevention box, lubricator; Being connected with a plurality of optical fiber Bragg raster flow transmitter arrays on the single-mode fiber in the high temperature resistant and high-pressure resistant optical cable is the optical fiber Bragg raster flow transmitter; Another single-mode fiber is standby single-mode fiber; The high temperature resistant and high-pressure resistant optical cable optic flow sensor places in the annular space between sleeve pipe and the oil pipe, and fiber optic conduction type structure and component are all adopted in the connection between the each several part.
The course of work of this system is as follows: sound wave emissions system in ground sends acoustic signals to the down-hole pinger, and pinger is launched acoustic signals to the down-hole, and acoustic signals is transferred on the downhole optic fiber sensor by well liquid; A branch of broadband light that light emitted goes out shines on the optic flow sensor through terrestrial transmission optical cable, down-hole high temperature resistant and high-pressure resistant optical cable, single-mode fiber, the arrowband light wave of different bragg wavelengths of each Fibre Optical Sensor reflected back.Any excitation to optical fiber Bragg raster influences as fluid flow size in the well, all will cause the change of this fiber grating bragg wavelength, change by ground demodulating system measuring center wavelength, carry out opto-electronic conversion through data processing unit, obtain the situation of change and the storage of liquid fluence in the well after A/D sampling and data are handled, be convenient to the data acquisition personnel and carry out data acquisition.
The utility model adopts optical fiber logging technique and device, reliable operation, utilize it can be under the HTHP bad working environments, under the situation that does not influence the production of oil gas well, the production fluid situation of all kinds of high temperature oil gas well different layers position is carried out permanent real-time monitoring, for oil gas well ordinary production and oil-gas reservoir reasonable development provide reliable basis.
