Title:
INTEGRATED FRACTURING FLUID AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/007750
Kind Code:
A1
Abstract:
The present invention provides an integrated fracturing fluid and a preparation method therefor. The fracturing fluid comprises: 0.02-0.5% of a drag-reducing and viscosity-increasing agent, 0.1-0.5% of a nano-emulsion, 0.02-0.1% of a nonionic fluorocarbon surfactant, 0.003-0.05% of a bactericide, 0-0.5% of a viscosity modifier, 0-0.5% of a clay stabilizer, 0-0.1% of a gel breaker, 0.05-0.2% of a modifier, and 0.1-0.5% of a gas generating agent, with the balance being water. The preparation method for the fracturing fluid comprises: adding a drag-reducing and viscosity-increasing agent into water, and adding a bactericide, a clay stabilizer, a modifier, a nano-emulsion and a nonionic fluorocarbon surfactant; adding a viscosity modifier according to viscosity requirements; and then adding a gas generating agent and a gel breaker; or adding the gas generating agent and the gel breaker to a sand mixing tank to be mixed with the mixed solution and sand together. The integrated fracturing fluid provided by the present invention has low friction drag, adjustable viscosity, and high sand suspension performance under the same viscosity.
