Description
Technical field
The invention belongs to petroleum technology field, and in particular to a kind of oil-in-water association type acidifying concentration thickening agent and its preparation
Method.
Background technology
As Low permeable oil and gas reservoirs are constantly developed, acid stimulation technology turns into the important measures of frscturing.Acidifying
That one kind makes that Oil/gas Well is stable, volume increase, water injection well is surely noted, the effective ways of augmented injection, be currently by oil gas well into stratum
A kind of (or several) acid solution of injection or acid mixed solution, occur chemistry anti-using the part mineral in the H+ and stratum in acid solution
Should, the wall rock cement of hole or crack in corrosion reservoir removes producing well injection well (water to improve in-place permeability
Well) pollution near shaft bottom, the permeability of renwing stratum, so as to well during releasing drilling well, completion, well workover and augmented injection etc.
The eye injury that nearby stratum is caused, dredges fluid neuron network passage, reaches the purpose recovered and improve oil gas well capacity, conventional
Acid liquid viscosity is low, and penetration depth is small, and filtration rate is fast, and pitting corrosion is caused around pit shaft, and acidifying transformation does not reach the effect of anticipation.
Viscous acid can effectively overcome the shortcoming of above-mentioned conventional acidulation technology.Viscous acid refer in acid add thickening agent (or
Claim gelling agent), increase acid liquid viscosity, effectively hydrogen ion diffusion rate in control acid solution, release the pollution in remote well area, link up
Oil gas flow-guiding channel, improves oil and gas production.
The key of viscous acid is thickening agent, the main natural polymerses of viscous acid thickening agent of current industrial application and
Polyacrylamide synthetic polymer, it exists following not enough：Heatproof, salt resistance, anti-shear performance are poor, and tackifying is poor, dissolubility
Preparation aspect needs to spend the more time difference at the scene, improves construction cost.Therefore, researcher proposes on this basis
Hydrophobic associated polymer gelling agent for acid fluid.Hydrophobically associating polymers (Hydrophobically Associating
Water-Soluble Polymers, HAWSP), refer to carry a small amount of hydrophobic grouping on polymer hydrophilicity macromolecular chain
Water-soluble polymer.In aqueous, HAWSP concentration is higher than after critical association concentration, and macromolecular chain passes through heat resistance and salt tolerance
Aggregation, solution viscosity significantly raises, and the system and possesses excellent thickening, heatproof, salt resistance, anti-shear performance.
The application performance of the above-mentioned hydrophobic associated polymer thickening technic acid being related to gradually has tended to be ripe, its site operation
Technique is mainly using " matching somebody with somebody marginal not in side ", i.e., continuous allocation process technology is exactly application at the scene directly by thickening agent dry powder, addition
Agent is mixed to form corresponding viscous acid working solution with acid.But current this continuous allocation process technology, some shortcomings are still suffered from,
Such as it is acidified labor intensity when thickening agent is prepared at the scene big, dry powder (thickening agent) feeds intake with dust greatly, mixes uneven, easily formed
Powder flake, produces local frozen glue caking, dissolves insufficient, influences solution property, and involved liquid, equipment and instrument are big
Increase construction cost and difficulty of construction greatly.
