【摘要】 以朝948加密区块杨大城子油层为研究对象,依靠油田密井网测井资料对区块加密后砂体平面展布特征进行再认识,指导区块加密后射孔、注采系统调整。对13口井19个测井解释为中水淹的沉积单元进行射孔,目前平均单井日产液4.3t/d,日产油3.7t/d,含水13.4%;确定转注井6口,转注后水驱控制程度由60.8%提高到78.6%,水驱储量由85.60×104t增加到108.76×104t。更多还原

【Abstract】 Aimed at the reservoir characteristics of Yangdachengzi oil layer in Chao 948,this paper further studies the plane distribution of single sand-body after infilling well pattern based on infill well logging data.After the block is perforated and injection-production system is adjusted.19 water-flood sedimentation units interpreted by log of 13 wells were perforated.At present,daily average fluid production is 4.3t/d,daily average oil production 3.7t/d,and water content is 13.4%.Six conversion wells were confirmed.The water drive control degree increased from 60.8% to 78.6% after conversion,and the oil reserves were enhanced from 85.60×104t to 108.76×104t.更多还原
