【摘要】 三角洲前缘亚相储集层横向变化较快,纵向非均质性强,如何提取三角洲前缘亚相储集层地震属性来描述其空间展布特征是三角洲前缘储集层预测的基础。以黄骅坳陷孔南地区地层发育特征为出发点,以已钻井资料为约束,优选出与已钻井资料匹配最好的地震均方根振幅及频率属性进行储集层预测,分析认为该地区有利储集层分布在G 984井—G 994井—G 40-62井一带以及G 36-80井以东区域。同时,通过对目的层段地层切片的提取与解释,对储集层展布规律及沉积演化特征进行分析,确定了油气有利评价地区。后经钻探证实,取得了较好的结果。更多还原

【Abstract】 Horizontal changes are great for the reservoirs in delta front sub-facies,vertical heterogeneity is strong.How to extract the seismic attributes of the reservoirs in delta front sub-facies to describe their features of space distribution is a foundation to predict delta front reservoirs.Taking the developing features of strata in Kongnan area of Huanghua depression as a starting point,and the drilled data as con-straints,reservoir prediction was carried out by optimizing seismic RMS amplitude and frequency attributes,they best matched with drilling data.The analysis showed the favorable reservoirs distributed in the belt of wells G 984-G 994-G 40-62 and the east area of well G 36-80.At the same time,through the extraction and interpretation for strata slicing of the target intervals,the reservoir distribution and sedimentary evolution features were analyzed to determine the regions that were favorable to oil and gas evaluation.The drilling showed good results.更多还原
