东濮凹陷濮城油田 6～ 1 0油藏是濮城长轴背斜东翼的一个断层油藏 ,产油层位是 Es中3 亚段 6～ 1 0砂层组 ,储层平均孔隙度为 1 2 .9% ,平均渗透率为 1 .9× 1 0 - 3 μm2 ;孔喉半径小 ,分选差 ,属特低渗储层 ,必须进行压裂改造才能生产。该油藏正式开发前必须进行注水开发先导试验 ,以寻找最佳的井网密度、适宜的注水压力 ;部署井网时要考虑人工裂缝的方位、长度和高度 ,从而提高低渗透油藏的开发效果 The 6 ~ 10 oil reservoir in Pucheng Oilfield of Dongpu Depression is a fault reservoir in the east wing of the long axis anticline of Pucheng. The oil-producing horizon is 6 ~ 10 sand group in Es 3 sub-stage. The average porosity of reservoir is 1 2 .9% with an average permeability of 1.9 × 10 -3 μm 2. The pore throat radius is small and the separation is poor, which belongs to the ultra-low permeability reservoir and must be fractured to produce it. Before the formal development of the reservoir, a pilot test of waterflood development must be conducted to find the optimal well density and the appropriate water injection pressure. The deployment of well patterns should take into account the orientation, length and height of artificial fractures so as to enhance the development of low-permeability reservoirs effect
