Compared to surface time-lapse seismic, time-lapse 3-D VSP is short in acquisition time, cheap, and easy-to-processing, and it is superior in repeated reservoir characterization, determination of optimal well position, calculation of reservoir properties in certain areas, monitoring fluid flow, and reduction of risk in equipment investment.

In most cases, time-lapse seismic is taken by repeated 3D seismics,so it is also called 4D seismics.There are many other time-lapse observation methods besides the 3D time lapse seismic such as time lapse 2D seismics,time-lapse cross hole seismic,time-lapse VSP etc.

由于大多數(shù)情況下，時移地震都是通過重復(fù)三維地震進(jìn)行的黄色网站免费精品在线观看，因此國內(nèi)外很多學(xué)者也將其稱為四維地震日本女优一区，除三維時移觀測外，還有很多其它的時移觀測方法啪啪啪一级，如時移二維地震在线观看黄A片、時移井間地震、時移VSP等欧美另类激情。

This paper briefly introduced the progress in time-lapse seismic as shown from the 76th SEG annual meeting. Topics include the repeatability of time-lapse seismic, in which we discussed the effects of shooting and receiving environments on repeatability, the effects of the cable length and its positioning accuracy and stability on repeatability, and the data processing techniques to improve repeatability, new insights into time-lapse seismic, in which we described tube wave time-lapse response, spectral decomposition, and time-lapse VSP monitoring, and problems related to application of time-lapse seismic technology. The comprehensive applications of time-lapse seismic and other geophysical data were demonstrated with the real data from an oilfield. Finally, we summarized the difficulties in using time-lapse seismic and outlooked its future trend.
