摘　　要：东濮凹陷濮城地区沙一段有利储层厚度薄且分布面积广,层间发育的盐岩层对地球物理信息具有较强屏蔽作用,导致该层段岩性油气藏隐蔽性较强。以研究区石油地质特征分析为基础,应用高精度三维地震资料解释技术与沉积相分析相结合,针对濮城地区沙一段陆相湖泊的沉积模式及砂泥岩薄互层和盐岩的特点,在最佳时窗范围内对不同层段、不同类型的地震属性进行筛选和优化,在此基础上进行储层预测并开展综合地质评价。通过该技术的应用,储层预测取得了较为理想的效果,在濮城地区沙一段上亚段落实了4个砂体,其中P1-400块目前已经获得突破。在此基础上落实了濮城地区勘探有利相带。The dominant reservoir in Sha I member of Pucheng area of Dongpu sag is thin and widely distributed.The stratigraphic reservoir in this formation can not be discerned clearly due to the salt bed that has blocked the geophysical information.By analyzing petroleum geological characteristic in study area,and using high precision seismic data interpretation and sediment facies analysis, and taking account of the terrestrial lake sedimentary model and features of interbedded thin sand-mud-salt in Sha I member of Pucheng area,we filter and optimize seismic attribute that have different segment and stratum type at the best time window so as to develop the reservoir forecasting and integrated geological estimation.The reservoir forecasting obtains better performance by using this technique for four sand bodies within Sha I member in Pucheng area.The P1-400 block has obtained breakthrough so far.The favorable exploration area is therefore based on this technique.
