Description
Technical field
The present invention relates to oil-gas field development technical field, especially relate to a kind of Shuangzi amphoteric viscoelastic surfactant and
Its preparation method and the clean fracturing fluid with it as thickening agent.
Background technology
The world today, the epoch relying on stratum natural energy to make oil go out from underground gurgle have terminated, global most
Large-scale Thief zone oil gas field comes into the exploitation later stage, and the demand of oil is but persistently being risen by countries in the world, domestic and international oil
The troop of exploration and exploitation starts to march to hypotonic, Oil in Super-low Permeability and unconventional limit oil-gas reservoir, and reservoir fracturing improvement becomes and carries
The key of high oil recovery factor, oil field produces the requirement to reservoir development degree and fracturing reform efficiency and improves constantly, conventional
Reservoir reconstruction (including reforming technology and working solution) exposes all drawbacks, especially with unconventional shale gas, fine and close oil
Deng exploitation, conventional reservoir reconstruction can not meet the requirement of current fracturing reform, and working solution is as " the spirit of reservoir reconstruction
Soul ", its quality decides the success or failure of modification measures, and the research and development of high performance operation liquid become current unconventionaloil pool Tibetan reservoir and change
Make middle problem demanding prompt solution.
Schlumberger in 1997, by viscoelastic surfactant fracturing fluid successful Application in reservoir fracturing improvement, starts
The research boom of clean fracturing fluid, oil and gas reservoir High Efficiency Reform low-grade to the world provide possibility.This fracturing fluid is with often
The difference of rule polymer fracturing fluid maximum is, it belongs to structural fluid, is shown as typical elastic fluid in a shear condition,
There is under low viscosity good prop-carrying capacity, broken natural or man-made polymer's fracturing fluid dependence fluid viscosity suspended prop
Normal mode, thus be conducive to the formation in long crack at a low viscosity, and breaking glue solution without residue, there is cleaning crack wall
Effect, fracture condudtiviy can be effectively improved, thus receive the extensive concern of oilfield.
But, due to surfactant unstability under the conditions of high temperature, high salt etc., and its side such as consumption, cost
The reason in face, clean fracturing fluid application in reservoir reconstruction receives serious restriction.It is prominent that current clean fracturing fluid exists
Ging wrong and have: (1) use cost is high, the viscoelastic surfactant that the clean fracturing fluid reported such as current document uses is biography
The single tail surface active agent of system, its critical micelle concentration is higher, and in actual application, consumption is too big, and cost is high；(2) according to the literature,
