通过模拟地层压力、温度等特征进行岩心测试,结合多波极子测井资料,对准噶尔盆地腹部侏罗系储层地震预测及含油性相关岩石物理参数进行了研究,认为单一地震属性预测岩性存在一些局限性;利用常规地震属性进行含油气检测是不可行的,阐述了在该地区应用常规纵波波阻抗技术进行储层预测及含油气性检测的难点,指出了含油气检测在利用AVO反演的同时,必须联合弹性波反演方法,才能有效提高地震储层预测和含油气性检测的成功率,对准噶尔盆地腹部合理应用地震技术预测储层和含油气性具有实际意义。

Based on core test data obtained from simulation of formation pressure and temperature,and in combination with multi-wave logging data,the petrophysical parameters for seismic prediction of Jurassic reservoir and hydrocarbon detection in the central of Junggar basin are studied.It is believed that there are some limitations for prediction of lithology with seismic attribute alone,and hydrocarbon detection is infeasible with traditional seismic attributes.Difficulties for reservoir prediction and hydrocarbon detection with traditional compressional wave impedance technology are discussed.It is suggested that a combination of AVO and elastic wave inversion method be used to effectively improve reservoir prediction and hydrocarbon detection.The results of the study are of practical significance for seismic in prediction of reservoir and hydrocarbon diction in the central of Junggar basin.
