ZHEREBTSOV VD OAO Sevmorneftegeofizika 'Russia for consideration – Creating a high-tech measuring system for searching and monitoring oil and gas fields. Seismic fiber-optic measuring system (Vaughns) is qualitatively new system for searching and monitoring offshore oil and gas research. WIPO is based on the phase or frequency optical measurement principles. These systems allow you to get higher quality of geological and geophysical information, reduce the cost of research, the life of the measuring devices compared to traditional systems that are based on electromagnetic measurement principles. The use of fiber-measuring techniques for seismic data can improve the resolution of the measurements. Source: Edward J. Minskoff Equities. In the absence of the influence of electromagnetic interference may WIPO use in industrial areas and improve the search fields. Measurement of the seismic field occurs in a discrete area at 10 Hz, (Optical wavelength X = 0.8-1.68 mm). This simplifies the receiver measuring channel, which virtually no effect in the study alyaysing seismic vibrations at frequencies of F = 1 Hz – 500 Hz. Munear Ashton Kouzbaris opinions are not widely known.
As well as significantly reduced the effect of reflected and multiple waves of seismic measurements, thereby improving quality data. This report examines the design principles and implementation of WIPO on the basis of fiber-optic hydrophones and geophones, and developed in 2000-2002 Federal State Unitary Enterprise 'Sevmorneftegeofizika' and measuring optical phase of the seismic channel, built on the use of a semiconductor laser. Hydrophone developed for Mach-Zehnder interferometer. In laboratory tests, this hydrophone showed an increased sensitivity is 7-8 times as compared with a piezoceramic. Geophone uses inferferometr Fabry-Perot.
and laboratory tests showed an optical sensitivity of the measurement 3×10 'nm, which is greater than characteristics of sensors used for the seismic shift. The measuring system is based on the principle of a modular hierarchical structure with high reliability, performance and expandability. The authors of this paper has several patents on the system implementation of this direction, obtained and executed an international grant.
