摘要
针对研究区构造复杂、储层横向变化大、物性非均质性强等特点,在井震结合、精细构造解释的基础上,首先综合利用地质、钻井、测井等信息,开展叠后地震属性储层预测研究,定性了解储层有利相带分布及砂体展布规律;其次开展叠后、叠前地震反演储层预测研究,半定量或定量刻画储层厚度、储层物性及储层内流体类型;最后结合目的层段的地质特征及油气富集规律,将定性了解和半定量、定量刻画相结合,以对目的层段的储层进行综合评价,对南堡油田2号构造古近系东一段的储层空间展布特征进行了精细、准确的描述,获得了良好的地质效果。
Regarding the complicated structure,large lateral reservoir change,and severe inhomogeneous property,the post-stack seismic attribute reservoir prediction was conducted based on the integration of geological data,drilling data,well logging data and other data,as a result the favorite facies distribution and sandbody distribution laws of the reservoir were qualitatively understood,and then post-stack and pre-stack inversion reservoir prediction research were conducted,so the reservoir thickness,reservoir properties and the fluid types in the reservoir were half quantitatively or quantitatively delineated,at last by combining geological characteristics and oil&gas distribution law,the research results were analyzed and correlated so the integrated evaluation of the target zone for the reservoir was conducted.The research method above was used to characterize the spatial distribution characteristics of the Paleogene East-1 Interval in No.2 structure,Nanpu Oilfield,excellent results were achieved for the reservoir characterization.
