摘要: 旅大5-2 油田生产层为疏松砂岩,胶结性差、流体携砂能力强,易出砂。科学确定生产压差,实施油井精细化管理,对于确保油井稳产,实现油田产能最大化意义重大。使用岩石力学方法确定旅大5-2 油田出砂临界生产压差,结合油藏地饱压差及油井实际生产状况研究结果,提出了旅大5-2 油田油井合理生产压差界限。

Abstract: Lvda 5-2 oilfield belongs to an unconsolidated sandstone reservoir, with the characteristics of poor cementation, strong sand carrying capacity of fluid, and easy sand production during exploitation. It is significant to determine producing pressure differential scientifically, implement refined management of oil well for ensuring stable production and achieve maximum oil productivity. The rock mechanics method is used to determine the critical sand production pressure differential in Lvda 5-2 oilfield. By combination with the research results of formation-saturation pressure differential and real production conditions, the limit of reasonable producing pressure differential of Lvda 5-2 oilfield is proposed.

Key words: Lvda 5-2 oilfield, unconsolidated sandstone, heavy oil reservoir, critical production pressure differential, reasonable producing pressure differential
