【摘要】 地震波阻抗反演技术是国内、外油气储层预测的关键技术之一。针对YK三维工区目的层砂体薄、横向变化快的特点,运用STRATA反演技术对其进行砂体预测。这里论述了STRA-TA反演的基本原理,实现流程,关键环节,以及在实际工区的运用。通过对反演结果的分析,明确了砂体的空间分布范围以及砂体的厚度,并做出了砂体视厚度平面分布图,对进一步勘探开发提供了明确的目标。更多还原

【Abstract】 Seismic impedance inversion technique is one of the key technologies to predict oil and gas reservoir in China and abroad.The paper applies strata inversion technique to predict the sand body aimed at the zone of interesting prospective in the YK 3D survey,which is characterized by thin sand body as well as the quickly lateral alternation.The author discusses the basic principle,realization of process,the key issues of strata inversion and the application in this survey.Through the analysis of inversion results,we can clarify the spatial distribution extent and thickness of the sand body,then make the distribution map of sand apparent thickness,which provides clear targets for further exploration and development.更多还原
