Description
Technical field
The present invention relates to oil gas field stimulation technology field, in particular to it is a kind of can mixture online integration
Composite emulsion type clean fracturing fluid and preparation method thereof.
Background technology
The unconventional petroleum resourceses such as domestic and international shale gas enrich, but in the majority with the low oil-gas reservoir with ultra-low penetration, therefore must
Fracturing reform must be carried out to it and improves oil and gas production.Pressure break is the technology of a transformation oil reservoir seepage characteristic, is oil/gas well
Volume increase, an important process measure of note solvent well augmented injection.Fracturing fluid is the bulk fluid in reservoir reconstruction.The performance of fracturing fluid
Directly affect the injectivity and productivity of fracturing effect and well.Existing fracturing fluid system is with guanidine glue pressure fluid and artificial polymer's fracturing fluid
Composition, general blocked water again by drop of fracturing fluid are formed with gelled fracturing fluid, and complicated seam net, but proppant can be formed by dropping the pressure break that blocks water
Concentration is low, and the fracture condudtiviy of formation is poor, and gelled fracturing fluid prop-carrying capacity is strong, but system viscosity is big, and construction friction is high.
Drop blocks water different with each additive of gelled fracturing fluid at this stage, and for the different demands for meeting reservoir,
The species of additive is more, more difficult to the quality control of every additive, while needs that drop blocks water before the construction of formal fracturing fluid
It is prepared with frozen glue pressure break, is stored in fluid reservoir, it is also more complicated, it is necessary to expend substantial amounts of human and material resources and wealth with liquid technique
