摘要: 针对目标区下第三系储层横向变化快,沉积特征不明显等特点,为提高滚动探井、开发井的钻探成功率,本文研制形成一套具有针对性的油气藏勘探预测研究方法.即运用多井约束波阻抗地震反演方法来预测砂体展布,同时对生成的地震波阻抗反演数据体中的振幅、厚度等暗含的有效信息进行提取,对砂体的分布范围及厚度变化进行准确而精细的描述和预测,最终依据此法优选有利相带,部署井位,取得了很好的勘探开发效果.

Abstract: Since the lower Paleogene reservoir characters varied quickly laterally and sedimentary characteristics are not obvious,we used seismic sparse spiking wave impedance inversion constrained by wells to predict the sand-body distribution in order to improve the drilling of exploration and development wells successfully.Combining the seismic amplitude,thickness and other useful information extracted from the seismic wave impedance data volume,we can understand the distribution range and thickness changes about sand body accurately,and get a better result of optimizing the favorable facies for improved well deployment.Finally,we form a set of prediction research methods for the hydrocarbon exploration and development in this area.
