Abstract
This paper introduces the theoretical study, pipe string structure, and technological characteristics of the siphon liner string used to develop the low permeability reservoir. This paper points out that due to the low production capacity, it is uneconomic to use the existing pump pipe string to produce oil from the low permeability reservoir. The study results indicate that the siphon liner string can reduce the pressure loss while fluid passing through, increase the suction pressure of pump, increase the speed of fluid flowing into the pump, and is beneficial for pulse plug removal. Field test proves that the siphon liner string can not only make the oil well recover production, but also can increase the output of it.
