摘要
油气储集层是典型的双相（同态相和流体相）介质。地震波在双相介质中传播时，会在地震记录上呈现明显的“低频共振、高频衰减”特征。基于这一理论并借助KLinversion软件平台，对新疆油田X井区的两套主力油层进行了油气检测，其结果与区内钻井测试结果的符合性良好，表明该检测方法能够降低钻探风险，为该区油气藏勘探的井位部署提供了有力依据，应用前景广阔。
Hydrocarbon reservoir is a typical two-phase （solid and fluid phases} media. The seismic wave propagating in two-phase media can display the characteristics of obvious low-frequency resonance and high-frequency attenuation in the seismic record. Based on the theory and with the help of KLinversion software platform, the hydrocarbon detection is can-led out in two sets of main reseiwoirs in X well field in Xinjiang Oilfield. The result accords well with the one from drilling testing in the area, which means that the detection method could lower the exploration drilling risk and provides the forceful basis for well location deployment of hydrocarbon reservoir exploration in the area, with the application prospect of the method being broad.
