Abstract
The invention relates to a method for water plugging and profile controlling of underground polymerization of oil exploitation sludge, comprising the following steps of: adding 2-7% of crylic acid, 0-3% of acrylamide, 0.2-0.6% of cross linking agent and 0.01-0.05% of initiator into 15-25% of oil exploitation sludge, injecting the mixture together with the oil field water or tap water in the ground; and subsequently generating plugging substances of solid mesh structure wrapping sludge owning to the polymerization reaction under the action of oil pool temperature, thus playing an effect of sealing the underground seams, wherein the oil exploitation sludge is a tank bottom sludge generated during the oil exploitation process of the oil field or the sludge in the sludge pool; the sludge is a thin oil sludge; the cross linking agent is a polyol, a glycerin, an N, N-methylene bisacrylamide or N, N-dimethybisacrylamide; and the initiator is the alkali metal salt or the ammonium salt of a persulphuric acid. The method changes the aboveground polymerization process of the oil exploitation sludge grain profile control agent into the underground polymerization process, saves corresponding procedures and the equipment and devices, and generates the water-plugging profile control agent with high intensity and long-term effect by adjusting the concentration of the monomer.
Description
Technical field
The present invention relates to a kind of method of water plugging and profile controlling of underground polymerization of oil exploitation sludge.
Background technology
Oil production sludge of oilfield is the discarded object that a kind of oil recovery process produces, and traditional processing method is a landfill method, this method contaminated environment, waste resource.Existing environmental regulation is forbidden landfill method.Existing non-landfill method mainly contains 1, high-temperature cracking method.2, the profile control and water plugging method.High-temperature cracking method mainly is at the higher heavy crude oily sludge of oil content, by Pintsch process the viscous crude in the mud is cracked into available thin oil.The profile control and water plugging method is heavy crude oily sludge to be made the profile control agent that uses in the oil field refill subsurface deposit, realizes sewage sludge harmlessness, resource.The profile control method mainly contains suspension method, emulsification suspension method, underground crosslinked method, ground polymerization.
Wherein, suspension method is to add thickener, dispersing agent, and mud granule is suspended, and is easy to pump into the stratum, carries out particle and stops up, the heavy dose of profile control of low-permeability oil deposit during this method is suitable, and shortcoming is that low being easy to of plugging strength discharged.The emulsification suspension method is to add emulsifier on the basis of suspension method, and the heavy crude oily sludge after emulsification is easy to pumping, and its shutoff mechanism is to utilize mud granule and emulsification oil droplet, the same suspension method of characteristics.Underground crosslinked method is to adopt the method for addition polymerization compound and crosslinking agent, and both can generate the solid netted frozen glue material that is enclosed with mud under the subsurface temperature effect, play the water plugging and profile controlling effect, and this method can heavy dose ofly be injected, but is not suitable for macropore.And the method for polymerization on the ground is after oil exploitation sludge is given processing through oil removing and desanding, on the ground in the factory equipment, adding unsaturated double-bond class monomer, initator, crosslinking agent carry out polymerization, granulation, drying, sieve into the profile control agent finished product in factory equipment, this method can be by making varigrained product, the oil reservoir that is used for different permeabilities, the macropore that is used for preferably.But this method needs to carry out a plurality of processes in the factory equipment on the ground.
Summary of the invention
Jar end thin oil mud that the objective of the invention is to produce in the oil recovery process of oil field or the thin oil mud in the sludge-tank, through oil removing with remove sand and give and handle the back adding and contain unsaturated double-bond class monomer, add initator and crosslinking agent again, inject underground, under the subsurface temperature effect, the reaction of said mixture generation polymeric chemical produces the space network property the stopped up material that is enclosed with mud, plays the effect in the underground seam of shutoff hole.
Method of the present invention is that acrylic acid, acrylamide and crosslinking agent are added in the oil recovery thin oil mud, implantation temperature 30-90 ℃ then, contain the underground of the following oil-field brine of salinity 150,000 mg/litre, under the reservoir temperature effect, produce polymerisation and generate the space network property the stopped up material that is enclosed with mud, play the effect in the underground seam of shutoff hole; Wherein, polymerizable monomer also can be only with the acrylic acid after the neutralization or only use acrylamide.
By weight percentage, acrylamide is 2-7%, and acrylic acid is 0-3%, and crosslinking agent is 0.2-0.6%, and initator is 0.01-0.05%, and oil recovery thin oil mud is 15-25%, oil-field brine or tap water surplus.
Described acrylic acid needs the alkali neutralization, and its alkali is sodium carbonate, NaOH, potash or potassium hydroxide.
Described crosslinking agent is polyalcohol, glycerine, N, N-methylene base bisacrylamide or N, N-dimethyl bisacrylamide.
Used initator is the alkali metal salts or ammonium salt of persulfuric acid.
The direct result that the present invention produces is that discarded object, the pollutant in this oil field of oil exploitation sludge of oil recovery process generation are turned waste into wealth, and has realized innoxious, the recycling of mud, and has saved the expense of mud conventional process.Simultaneously, this method can be produced the mud profile control method of mentioning than all background technologies and stop up the higher profile-controlling and plugging agent of intensity; This method is suitable for temperature 30--90 ℃, the following oil-field brine of salinity 150,000 mg/litre.
Oil exploitation sludge granular profile control agent ground polymerization process is changed into the underground polymerization process, save the Ju He Zao Li oven dry screening operation of preparing product on the ground, save corresponding operation and apparatus, produce high-strength long-acting water plugging profile control agent by adjusting monomer concentration.
The specific embodiment
Embodiment 1
In 200ml glass reaction container, add 10 and restrain the aqueous solution that contains acrylamide 31.5%, add good oil exploitation sludge (meter of giving money as a gift) 15 grams of preliminary treatment after the oil removing desanding again, add the tap water surplus, mix, and then add glycerine 0.3 gram, ammonium persulfate 0.03 gram, mix and carry out polymerisation in the baking oven that is placed on uniform temperature.
Embodiment 2
In 200ml glass reaction container, add 2 gram acrylamide crystals and 2 gram acrylic acids (acrylic acid need be neutralized into PAA with alkali) 200, add again through good oil exploitation sludge 20 grams (meter of giving money as a gift) of oil removing desanding preliminary treatment, add oilfield sewage 75.68 grams then, mix.And then add N, N-methylene base bisacrylamide 0.3 gram, ammonium persulfate 0.02 gram, mix in the baking oven that is placed on uniform temperature polymerization get final product needed product.
