Description
Technical field
The present invention relates to a kind of adhesive films to stablize gravel packing zone sand-preventing process, belongs to petroleum works technical field.
Background technology
Reservoir fine migration (as shown in Figure 1) is adjoint in each stage of petroleum production engineering, when fluid-flow rate is big in reservoir
When the maximum critical flow velocity of fine migration in hole, a series of serious problems from stratum to ground can be caused, such as：Reservoir
Productivity decline is rapid, filter sand blockage, holddown, ground solid pollutant increase etc..The big pump extract of block since the Shengli Oil Field
Since pilot, since fine migration blocks oil well productivity decline rapid (as shown in Figure 2) caused by gravel packing zone in reservoir
Problem is more prominent, and it is equally prominent to block the problem of oil well productivity caused by sand screen declines after reservoir particle inflow pit shaft.It can
See, it is the key that extend oil well productivity, improve the sand control life effectively to control reservoir fine migration and block gravel packing zone.
Widely used cationic polymer presses down sand agent due to the limitation in structure and performance in sand control pack technique at present
The requirement that current big pump extract, long-acting sand control and acidification control fine migration is not adapted to：One, cationic polymer
Suppression sand agent water solubility can be dissolved into water flooding again with the extension of production time, remain in the active ingredient of hole table wall by ground
Layer salinity and shear action influence can be denaturalized chain rupture, and successively decreasing, which causes to press down rapidly grittiness, to fall sharply；Secondly, remain in hole and micro-
The cationic polymer of grain table wall only leans on Electrostatic Absorption and hydrogen bond action suppression grittiness can faint, resistance to erosion discharge capacity only 900ml/h；Its
Three, cationic polymer can be caused in middle low permeability reservoir improper use by reservoir damage.It is although pre-coated with from consolidated proppants
Machine film, but only meet itself consolidation under the conditions of underground and generate intensity, this precoating organic film does not have viscosity property, because without
The formation fines of intrusion filling layer can be adhered to.Therefore, it is necessary to provide a kind of new adhesive film stabilization gravel packing zone sand control work
Skill.
Invention content
For the above-mentioned prior art, the present invention provides a kind of adhesive films to stablize gravel packing zone sand-preventing process, the technique

With), promote film spreading to invade the particle of filling layer after ultra-thin adhesive film by water driving force and film forming agent intrinsic viscosity
Be adhered to around back-up sand, will not migrate so that block filling layer hole, to for a long time keep filling layer high osmosis and
Stability.
The adhesive film of the present invention stablizes gravel packing zone sand-preventing process, washes away discharge capacity and reaches 7000ml/h, outlet sand content <
0.5g/L (evaluation method uses in Q/SH1020 2377-2015 5.5)；It is applicable in reservoir and permeates > 10md, rock core infiltration retains
Rate > 90% (evaluation method uses in Q/SLCG0097-2014 4.7)；Extend sand control measure oil-water well term of validity > half a year.
The adhesive film of the present invention stablizes gravel packing zone sand-preventing process, and section plug pump note technique promotes to generate adhesive film
(film-forming state is precipitated in alcohol-soluble film forming agent water as shown in figure 4, adhesive film fixation in situ particle displaing micro picture is as shown in Figure 5.Alcohol
When insoluble film former selects a concentration of 10% ethanol solution of 650 amide resins, adhesive film stablizes gravel packing zone corpuscular property
Energy tables of data is as shown in table 1, and the influence tables of data to in-place permeability is as shown in table 2), reservoir permeability is neither injured, is kept
Compared with high flow conductivity, but significantly improve filling sand body stability, facilitate construction, have safety and environmental protection, construction is simple, film forming soon,
The features such as resistance to erosion ability is strong is the new process that mid-late oilfield development extends sand control filling stable production period, promotes and applies valence
It is worth big, strong applicability.
