随着4D地震技术的不断发展,国外已经有很多地区成功应用4D地震技术提高剩余油表征精度,增加原油产量,并将4D地震列入日常的油藏管理常规技术。4D地震在油藏精细表征技术中发挥着重要的作用,是未来的发展趋势。在北海、墨西哥湾等地区的油田上应用4D地震对提高非均质油藏剩余油采收率产生了重大的影响。
With the continuous development of 4D seismic technology, many overseas regions have successfully applied 4D seismic technology to improve the remaining oil characterization accuracy, increase crude oil output and include 4D earthquakes in routine routine reservoir management technologies. The 4D earthquake plays an important role in the fine characterization of reservoirs and is the future trend of development. The application of 4D earthquake to the oil fields in the North Sea and Gulf of Mexico has greatly affected the recovery of remaining oil in heterogeneous reservoirs.
