Abstract

Abstract:

The development and production of low-permeability oil reservoirs have been staggered by problems such as low recovery factor and low efficiency of waterflooding,singular direction of fluid flow and etc.How to effectively develop this kind of reservoirs therefore has gained more and more attention around the world in recent years.The paper discussed a study on the application of a flow direction changing method with hydrodynamic force in the Baobei block of the Baolang oilfield in Xinjiang Autonomous region.The study suggests that there are three ways of changing flow direction with the hydrodynamic force:water injector adjustments,producer adjustment and conversion of producers to injectors.Based on practical geological and production data of the oilfield,the study offered practical measures for changing flow direction in 52 producers through infilling injectors and adjusting producing layers.An evaluation was also carried out by using reservoir numerical simulation model to check the effectiveness of these measures during the study.The model predicts increases in comprehensive water cut by 6.36%,oil production by 265,100 tons and daily oil output by 59.34 tons fifteen years after the measures being taken.Based on the prediction,the paper comes to the conclusion that the method can effectively impede water cut increasing,increase single production,and enhance waterflooding recovery factor in oil reservoirs with low permeability.

Key words: flow direction change method, numerical simulation, water-flooding recovery factor, low-permeability reservoir, Baolang oilfield, Xinjiang
