西达里亚油田三叠系油藏上油组属于层状边水油藏,储层物性主要表现出中孔、中渗特征,在前期的开发过程中主要表现出供液能力差、间抽生产等开发现象,经过注水开发后,水驱控制储量和采收率等开发指标得到改善,评价目前开发方式效果较好,认为油藏有很大的改善注水潜力。 The Triassic oil-bearing oil-bearing formation in the Western Daria oil field belongs to the layered edge water reservoir. The reservoir properties mainly show the characteristics of mid-porosity and medium-permeability. During the early development, the oil-reservoirs mainly showed poor liquid supply capacity and inter-pumping Production and other development phenomena. After the development of waterflooding, development indicators such as controlled reserves of waterflooding and oil recovery have been improved. Evaluation of the current development methods is effective and it is believed that the reservoir has great potential for improving waterflooding.
