Oriental Geophysical Hebei applied optical fiber sensing technology in VSP project of Xinmiao 1 well in East Oilfield to collect new results
.
Recently, the reporter learned the news
.
The application of optical fiber sensing technology in seismic exploration can make up for the problems of low sensitivity, small dynamic range and poor anti-electromagnetic interference of geophones, and find the right direction
for the research and development of new geophones.
Compared with traditional geophones, fiber-optic geophones have the advantages of large dynamic range, high sensitivity, simple structure, and anti-electromagnetic interference, which play an important role
in improving the quality of seismic data.
In the operation of the project, the operation team of Xinxing Geophysical Development Division successfully used optical fiber sensing technology to carry out acquisition operations
.
Conventional VSP detector multi-stage downhole equipment requires multiple excitations, which is labor-intensive and time-consuming
.
The offset distance of the distributed optical fiber only needs one excitation, the construction efficiency is high, and the high-density VSP data can be collected, and the wavelet consistency of the whole well section is good, which provides a guarantee
for imaging research.
At the same time, the VSP data processing method of optical fiber acquisition can obtain high-resolution VSP imaging profile, which provides basic data
for fine interpretation at the well.
Through optical fiber sensing technology, the project improves the acquisition capability of Walkaway-VSP and lays a foundation
for the next step of technology application and promotion.
