Description
Technical field
The invention belongs to the oilfield chemical auxiliary technical field, be specifically related to a kind of fracturing fluid recovery (backflow) agent that is used for the wellfracturing construction.
Background technology
At present, the pressure break of oil well is to utilize hydraulic action, makes oil reservoir form fissured a kind of method, claims petrofracturing again.The wellfracturing technological process is to use fracturing truck, the liquid that high-pressure large-displacement is had certain viscosity is clamp-oned oil reservoir, after oil reservoir is extruded many cracks, add propping agent (as quartz sand etc.) filling and enter the crack, improve the penetrating power of oil reservoir, to increase water injection rate (water injection well) or oil offtake (oil well).
Fracturing liquid in the pressing crack construction process normally adds polymkeric substance such as melon glue, the blue or green glue in field to improve fracturing liquid viscosity, construction requirement finishes the in time broken glue in back at pressing crack construction, return to the low viscosity state of good fluidity, to realize that efficiently returning current drainage from the crack returns pit shaft, therefore, in fracturing liquid, added gel breaker.But in the actually operating, the gel breaker add-on is excessive can to cause that again fracturing liquid viscosity reduces too early, makes the propping agent that carries in the fracturing liquid shift to an earlier date rapid subsidence and " sand plug " occur, causes the construction failure.If the gel breaker consumption very little, then fracturing liquid rubber-breaking is not thorough again, and viscosity is difficult to thorough reduction, and fracture flow capacity is descended, even makes most of polymkeric substance concentrate the formation filter cake in fracture faces, causes the construction failure, and fracturing liquid is stayed in the stratum, polluted reservoir.In recent years a kind of " capsule breaker " succeeded in developing utilizes extruding or osmosis to discharge broken glue active substance after injecting the stratum, and this method can partly be improved fissured flow conductivity, but its cost is too high, and effect also is difficult to satisfied.In pressing crack construction process, also have to add the fracturing fluid recovery (backflow) agent, but be pure acids mostly, flowback effect is poor, is difficult to satisfy construction requirement.
Summary of the invention
The present invention provides a kind of fracturing fluid recovery (backflow) agent that is used for the wellfracturing construction for overcoming defective of the prior art, and it can make fracturing liquid return efficiently and be discharged in the pit shaft, and has cleaning function, satisfies the requirement of various construction environments.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of fracturing fluid recovery (backflow) agent that is used for the wellfracturing construction of the present invention, it is made up of the material of following parts by weight: carbon dioxide generation agent 40～90, tensio-active agent 2～8, permeate agent 3～6, vitriol 4～15, oxygenant 6～24, clay stablizer 4～12, water 80～200.

Preferably, described a kind of fracturing fluid recovery (backflow) agent that is used for the wellfracturing construction, it is made up of the material of following parts by weight: carbon dioxide generation agent 50～80, tensio-active agent 3～6, permeate agent 4～6, vitriol 5～12, oxygenant 10～20, clay stablizer 5～10, water 100～180.
Preferably, described a kind of fracturing fluid recovery (backflow) agent that is used for the wellfracturing construction, it is made up of the material of following parts by weight: sodium bicarbonate 60, sodium lauryl sulphate 5, maleic acid di-sec-octyl sodium sulfonate 5, sodium sulfate 9, Potassium Persulphate 15, Repone K 8, water 150.
When using, product of the present invention before fracturing liquid adds, is injected into oil reservoir, the effect of each component in the fracturing fluid recovery (backflow) agent:
Be injected into oil reservoir under carbon dioxide generation agent---the high pressure,, produce the carbon dioxide of capacity with of the fracturing fluid preposition acid liquid reaction, be dissolved in the solution under the high pressure effect, when pressing crack construction finished to put the pressure row of returning, carbonic acid gas was separated out from solution, promote fracturing liquid and enter pit shaft, discharge.
Tensio-active agent---have good emulsifying, foaming, lubricated, ability of cleaning greasy dirt, play thick-oil emulsified adhesive-reducing, oil reservoir helps row to act on.
Permeate agent---the energy rapid osmotic is in materials such as filter cake, pitch, colloid, and is composite with vitriol and oxygenant, and pitch, colloid and paraffin are had good solvency action.
Vitriol---the dirt effect of deoiling is strong, with permeate agent, oxygenant agent filter cake, drop table, gelationus is dissolved with promoter action.
Oxygenant---a kind of gel breaker can further break the glue viscosity reduction in the row's of returning process, strengthen of the fracturing fluid flowability.
The clay stablizer---can suppress stratum clay swelling and clay fine migration.
The beneficial effect that the present invention compared with prior art has is:
The invention solves the difficult problem in the present pressing crack construction technology, fracturing liquid is returned efficiently be discharged in the pit shaft, and have cleaning function, satisfy the requirement of various construction environments, boundless application prospect is arranged.
