摘要
在生产实践中,用亮点检测油气技术比较成熟,而利用暗点检测油气尚处于探索阶段。暗点在地震剖面上以弱振幅形式出现,在识别技术上存在一定的难度,但由于暗点也指示油气,因此从技术上讨论暗点的反射特征是必要的。依据辽河盆地东部浅海地区连井地震剖面的AVO资料,探讨了亮点和暗点的解释方法,并利用亮点和暗点特征检测了储集层的含油气性。
In practice,bright spot detection technique for oil and gas has been relatively mature,while the dim spot detection technique is under research.In seismic profile,the dim spot appears in the mode of weak amplitude,so,there still exist some difficulty in identification.The dim spot can also indicate oil and gas,and it is necessary to technically discuss the reflection characteristics of dim spot.Based on the AVO data of seismic profile from the shallow marine area in the east of Liaohe basin,the interpretation methods for the bright spot and the dim spot are discussed,and the bright spot and dim spot characteristics are used to detect the hydrocarbon bearing features of reservoirs.
