叠前裂缝检测技术浅谈
|
摘要
目前在全世界范围进行的油气勘探开发过程中,裂缝性油气藏所占的比例越来越大。因此,裂缝性油气藏的勘探对我国未来石油工业的发展有着十分重要的意义。以往使用测井数据来进行裂缝检测,其检测结果大多数只在井点周围很小的范围内有效。FRS系统利用叠前地震资料信息研究裂缝的特征,在处理过程中综合运用与裂缝有关的地质、地球物理、测井和岩石物理等信息,实现对裂缝方位、裂缝密度、流体饱和度等各项参数的描述,解决裂缝油气藏勘探所面临的难题。通过在牛东地区的应用,收到了一定的效果。
At present,fractured hydrocarbon reservoir takes more and more significant position in the oil and gas exploration in the whole world,so its exploration is significance to the future development of oil industry of our country.The result of using well logging to detect the fracture was available only around small area of well spot in the past.FRS system uses prestack seismic information to study fracture.During the process,integrated information such as geology,geophysics,well logging and rock physics,related with fracture are used;description of various parameters such as fracture azimuth,fracture density as well as fluid saturation is realized;difficulties that fractured hydrocarbon reservoir meets in the exploration are solved.The application in Niudong region has taken a good result..
