Status and developmemt trend of fracturing-flooding technology in low pemeability reservoirs
Fracturing-flooding technology is a kind of reservoir stimulation technology to increase reservoir producing degree and enhance oil recovery,which is put forward for the efficient development of low permeability reservoirs in recent years.The fracturing-flooding technology firstly injects a large amount of liquid carrying chemical agent into the formation through high pressure and small displacement,and then soaks the well.Through the diffusion of pressure and the full replacement of chemical agent with the crude oil in fracture pores,the purpose of increasing production is achieved.Based on the latest research trends of fracturing-flooding technology at home and abroad,this paper discusses the present situation,design principle,design method,application analysis and development trend of fracturing-flooding technology,focusing on the analysis of the differences between fracturing-flooding technology and hydraulic fracturing technology,the mechanism of increasing production,design method and field application.At the same time,this paper points out the current deficiency of theoretical research of fracturing-flooding technology,and prospects the development trend and application prospect of this technology.
