【摘要】 目前储层描述主要有反演和地震属性2种方法,但在中拐地区应用效果都不理想,因此,井震相关选优法储层预测技术也就应运而生。该方法要求首先在地震上标定砂体的位置,然后在区内每口单井上划出砂厚,第三步在包含砂体的地震时窗内提取尽量多的地震属性,第四步用单井砂厚和地震属性做相关,找出相关性高的地震属性预测砂体,最后,结合正演指出区内含油气的有利区。该方法在研究区取得了很好的效果,具有很强的推广性。更多还原

【Abstract】 Well seismic and surface seismic joint method is superior to others. It may be divided into 4 steps. The first step is delineating location of sand body in all the wells. The second step is determining thickness of the sand body in single well. The third is seismic attribute extraction in seismic time window. The fourth step is correlation analysis of seismic attribute extraction with thickness of the sand body in single well.更多还原
