Description

The preparation and application that the anti-swollen contracting of a kind of small molecules is swollen dose
Technical field
The present invention relates to anti-swollen dose of preparing technical field of swollen contracting, be specifically related to the preparation and application of swollen dose of the anti-swollen contracting of a kind of small molecules.
Background technology
The main component of mud shale is clay mineral, layer mineral---the montmorillonite that wherein the superfine hydrous alumino silicates of particle forms, in its structure, reactive force is between layers weak Van der Waals force, with water base oilfield working fluids interaction process in easily water-swelling.The Complicated Fault Block Oilfield of low permeability and high pressure, clay mineral content is high, meets water and easily expands, migrates, and causes permeability plugging, and water injection pressure rises, and oil recovery ratio declines.The injuries that adopt the method for water filling initial stage interpolation clay stabilizer to slow down clay class mineral pair reservoir in the actual production of oil field at present more.For the situation of hydration swelling of clay mineral, traditional clay stabilizer is that expansion-resisting agent is very little to the restitution of reservoir penetrating power.For this situation, mainly take at present acidification to dispel block measure to remove reservoir pollution, but conventional souring method has, treatment radius is little, validity period is short, acidizing fluid itself injures the defects such as large to oil reservoir.
Contract swollen dose and have the anti-swollen function of traditional clay stabilizer concurrently, can make the clay dehydration of hydration swelling contract swollen, recover the penetrating power of reservoir.The research that at present domestic relevant contracting is swollen dose is less, and basic is all relative molecular mass at 1000 ~ 100000 organic cationic polymer.But because its molecular weight is larger, on the one hand molecular weight is excessive has limited its application at low permeability oil field, can only be adsorbed on the other hand clay surface, for the strong clay of swelling property, the inhibition of polyamine class shale clay swelling inhibitor is unsatisfactory.In addition, part polyamine class shale clay swelling inhibitor also exist toxicity large, with the problems such as anionic treatments agent compatibleness is poor.
Summary of the invention
In order to overcome the shortcoming of prior art, the object of the present invention is to provide the preparation and application of swollen dose of the anti-swollen contracting of a kind of small molecules, small molecules prevents that the molecular weight of swollen dose of swollen contracting is little, rejection good, environmental friendliness.
In order to achieve the above object, the technical solution used in the present invention is:
The preparation that the anti-swollen contracting of small molecules is swollen dose, comprises the following steps:
The first step, in reactor, amine is dissolved in 5-30 solvent doubly, stir, described amine is thanomin, diethanolamine, trolamine, quadrol, diethylenetriamine, triethylene tetramine, tetraethylene pentamine, five ethene hexamines of technical grade and above purity thereof and composition thereof, and described solvent is water of technical grade and above purity methyl alcohol, ethanol or the above purity of tap water and composition thereof;
Second step, under stirring to add in above-mentioned solution with amine in the amido functional group ratio carboxylic acid that is 1:1-5, described carboxylic acid is lactic acid, oxysuccinic acid, tartrate, citric acid, gluconic acid, L-glutamic acid of technical grade and above purity thereof and composition thereof;
The 3rd step, is heated to 30-100 DEG C by said mixture, all dissolves to it;
The 4th step, boils off solvent in said mixture, is cooled to room temperature;
The 5th step, is transferred to said mixture in mortar, and the Repone K that to add with amine and carboxylic acid total mass ratio be 5-0.5:1 grinds evenly, obtains swollen dose of the anti-swollen contracting of small molecules, and described Repone K is the product of technical grade and above purity thereof.
When application, the 0.1-2.0% that the anti-swollen dose of consumption of swollen contracting of small molecules is oilfield working fluids quality, its anti-swollen rate to clay is 50-80%, the swollen rate that contracts is greater than 20%.
Advantage of the present invention: repair mud stone bioactive molecule and clay mineral (montmorillonite, illite) generation physical-chemical reaction behind swollen dose of injection stratum of the anti-swollen contracting of small molecules, make clay lattice modification, make not expand after its chance water; The clay lattice having expanded, by discharging water molecules after chemical reaction modification, lattice dwindles.Bioactive molecule enters calmly pore space widely, reduce surface tension, eliminate the water blocking damage of large particle water, clean stratum, and make clay material and the former stratum mineral mortise of these modifications by multipoint adsorption effect, meet water injury thereby removed clay mineral, water lock, the injury that water-sensitive expands, migration causes stratum, reach step-down augmented injection, recover effective permeability, improve the outstanding effect of oil and gas development.
