Determination of Reasonable Producing Pressure Differential of Lvda 5-2 Oilfield

Abstract

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
