Abstract
A gelating liquid for blocking water and regulating the water suction profile in stratum for oil reservoir is prepared from lignosulfonate, phenol, aldehyde, sulfonated tannin extract, polymer and zinc chloride through cross-linking instead of modifying, and features simple process, no need of preparing intermediate, and high effect to block water layer of oil-bearing stratum and regulate the ambient water suction profile of oil well.
Description
The invention belongs to the gelatinizing liquid method for making of a kind of oil reservoir water blockoff and adjustment stratum intake profile.
The oil field water outlet is the universal phenomenon that the oil field of waterflooding runs into.Along with the propelling of waterside edge, because formation heterogeneity, reason such as the difference of profit mobility ratio and mode of operation are improper, oil reservoir may be crossed early leaving, and oil recovery factor is reduced.For this reason, need carry out shutoff to water outlet.
In addition, because formation heterogeneity, the water overwhelming majority of injecting the stratum is absorbed by the little high permeability zone of thickness, causes input profile very inhomogeneous.In order to improve the sweep efficiency that injects water, can inject gelatinizing liquid to oil reservoir, reduce the rate of permeation of high permeability formation, thereby adjust intake profile.
By product Sulfite lignin with pulp and paper industry are that main raw material is made gelatinizing liquid, can be used as plugging agent or amendment, and abundant raw material is cheap.In order to improve the visco-elasticity of gel, people have proposed the notion of composite plugging agent, be not only to contain Sulfite lignin and dichromate in the gelatinizing liquid, also contain polymkeric substance (generally being polyacrylamide or modified polyacrylamide) (Xie Tongcheng etc., " oilfield chemistry " 1986 the 3rd the 3rd phases of volume).This gelling system because of adding a large amount of deleterious dichromates, easily pollutes environment, and use range is dwindled at present.Horse bezoar qi etc. is developed a kind of gelatinizing liquid (" oilfield chemistry ", nineteen ninety, the 7th volume, the 1st phase) that contains modified lignin sulfonate and polyacrylamide, is applicable to that temperature is 70～90 ℃ stratum.This blocking agent becomes glue slow, is particularly suitable for heavy dose of the injection.But sodium lignosulfonate needs through modification, and preparation technology is complicated.Chen Fan more waits the method for modifying of Sulfite lignin has been done improvement, makes Applicable temperature range extension to 50～90 ℃ of gelatinizing liquid, and the pH value scope that is suitable for was 5.0～6.5 (" oilfield chemistries ",, the 10th volume, the 4th phases in 1993).All there is the shortcoming of complex process in above-mentioned two kinds of methods, and the gelatinizing liquid of preparation can only be used under acidic conditions.
The objective of the invention is to overcome the shortcoming that has Chrome-free Sulfite lignin-polymkeric substance blocking agent preparation method complexity now, can not under neutrality or weak basic condition, use, improve its performance, enlarge its scope of application.
The preparation method of gelatinizing liquid provided by the invention, adopt Sulfite lignin and phenol, aldehyde and polymkeric substance to carry out crosslinked, be characterized in Sulfite lignin not being carried out modification, also need not prepare intermediate product, but directly preparation, earlier with polymer dissolution in water, add Sulfite lignin, phenol, aldehyde, sulfonation condensation tannin extract, zinc chloride again, regulate pH value to 5～6 at last, or with all components difference wiring solution-forming, again by the mixed in the prescription.Contain in the representative formula:
Sulfite lignin 2.0%～5.0% phenol 0.1%～0.5%
Aldehyde 0.2%～0.8% sulfonation tannin extract 0.01%～0.05%
Polymkeric substance 0.2%～0.6% zinc chloride 0.01%～0.05%
The used Sulfite lignin of the present invention can be any sodium lignosulfonates that is made through acid sulfite cooking by timber, phenol can be any in phenol, cresols, pyrocatechol and the Resorcinol, aldehyde can be any in formaldehyde, acetaldehyde, the furtural, and polymkeric substance can be polyacrylamide or type methylene polyacrylamide.Polyacrylamide both can be with unhydrolyzed, also can be with partial hydrolysis, the degree of hydrolysis of partially hydrolyzed polyacrylamide is not higher than 30%.The average molecular mass of polymkeric substance should be controlled at 3 * 10
6～1 * 10
7Between.In the present invention, if Sulfite lignin are to make with the raw material that contains condensed tannin, then can not add sulfonation condensation tannin extract in the prescription.
With the gelatinizing liquid of the method for the invention preparation, viscosity is 20～80mPas at normal temperatures, and it can generate viscosity greater than 10 in pH value 5～7.5,50～95 ℃ of scopes of temperature
5The elastogel of mPas, it is controlled between 6～72h to generate the gel required time, and the gel viscosity of generation is 10
5More than the mPas.The gel heatproof can reach 105 ℃.It both can be used for the reservoir plugging water outlet, also can be used for changing water injection well intake profile on every side.To the gas-phase permeation rate is 1.0～10.0 μ m
2Synthetic core inject gelatinizing liquid, 90 ℃ become glue after, recording shutoff efficient can reach more than 95%.The rock core parallel connection that rate of permeation is different under constant speed displacement condition, is annotated the intake profile that divides the mode of adopting to study rock core with closing.The result shows, before the injecting profile control agent, high infiltration rock core water regain accounts for more than 90% of total suction, and the hyposmosis rock core does not absorb water substantially, behind the injecting profile control agent, amendment mainly enters high infiltration rock core, after becoming glue, the rock core water regain that rate of permeation is the highest drops to below 40%, and the minimum rock core of rate of permeation, water regain also rises to 6%, this show intake profile be improved significantly.During on-the-spot the use, gelatinizing liquid is injected the stratum, gelatinizing liquid is delay cross linking under formation temperature, forms gel, thus shutoff water outlet band or high permeability zone.When the stratum was not higher than 100 ℃ when the stratum temperature, the gel validity period of generation can reach 6 months.After gelatinizing liquid is injected the stratum,, only need be 1%～3% sodium hydroxide solution, can make the gel dissolving of generation to the stratum implantation concentration if need to remove the shutoff of gel for some reason to the stratum.
