Research status of low permeability shale reservoir fracturing and integrated fracturing fluids
Conventional petroleum gas resources are increasingly reduced,and the competition for energy resources is becoming increasingly fierce.Unconventional oil and gas reservoirs such as shale oil and gas,which are widely distributed and rich in reserves,have become the focus of fossil energy development.The shale reservoir has the characteristics of low porosity and low permeability,which is difficult to create fractures.It is necessary to use large-scale fracturing to communicate natural micro-fractures and widen oil and gas channels,so as to form stable industrial gas flow to increase production.The traditional on-site powder dispensing mode gradually fails to meet the requirements of fracturing operations.Therefore,based on the advantages and disadvantages of integrated slick water fracturing fluid and its application in shale oil and gas exploitation,the application status and related characteristics of integrated suspension fracturing fluid at home and abroad are briefly discussed,and the development direction and characteristics of unconventional fracturing fluid under the hot trends such as low damage and environmental friendliness are comprehensively discussed.
