Description
Technical field
The present invention relates to employed oilfield chemistry agent-anti-clayswelling agent and preparation method thereof in a kind of oil and gas oil producing operation construction, be mainly used in water filling, acidifying and the well control fluid.
Background technology
The present anti-clayswelling agent (being called clay stabilizer again) that in the oil and gas exploitation construction, uses, product category is various, and conclude and get up to have several classes: 1. inorganic salts comprises Repone K, ammonium chloride, oxyaluminum, iron carbonyl etc.; 2. organic salt comprises Guanidinium hydrochloride, guanidine acetate, pyridinium salt, imidazoline salt etc.; 3. organic cation type polymer class comprises poly--2-hydroxypropyl alkyl dimethyl ammonium chloride, diallyl dimethyl ammoniumchloride, cationic polyacrylamide, epoxy chloropropionate alkene-polyethylene polyamine polycondensate, polyacrylamide propylene ethoxycarbonyl trimethyl ammonium chloride etc.The inorganic salts expansion-resisting agent is water-fast, and the stream performance of flushing is poor, and the organic salt expansion-resisting agent reduces the wetting ability of rock surface, makes the ability drop of water displacing oil.Organic cation type polymkeric substance heatproof, acidproof, oil resistant, validity period is long, and is anti-swollen effective.Its molecular structure of organic cation type expansion-resisting agent that uses is mainly straight chain or reticulated structure at present, and when molecular weight hour anti-swollen weak effect, throwing out can cause the stratum permeability injury when molecular weight is big, especially at middle low permeability reservoir.
Summary of the invention
The object of the present invention is to provide a kind of three branched structures, anti-swollen effective, do not injure stratum and anti-clayswelling agent with low cost and preparation method thereof.
Clay antiswelling agent for petroleum extraction of the present invention is to be made of diallyl ammonium chloride and the triallyl amine monomers mass percent by following component: diallyl ammonium chloride: triallylamine=50～90%: 10～50%.
The diallyl ammonium chloride monomer is diallyl ammonium chloride, diallyl-ammonio methacrylate, diallyldimethylammonium chloride or diallyl diethyl ammonium chloride.
The triallyl amine monomers is triallylamine, triallyl-methylamine or triallyl second.
Clay antiswelling agent for petroleum extraction of the present invention is to be made of diallyl ammonium chloride and the triallyl amine monomers mass percent in following ratio: diallyl ammonium chloride: triallylamine=50～90%: 10～50%.Two kinds of monomers are dissolved in the distilled water, and total concn is at 20～80% (mass percent concentrations), and optimum concn is 30～50%; Temperature of reaction is 10～100 ℃, and optimum temps is 65～85 ℃; Add initiator under nitrogen protection, initiator is a superoxide, and as ammonium persulphate, Potassium Persulphate or hydrogen peroxide, it is 0.01～0.1% of two kinds of monomer total masses that initiator adds quality.Polyreaction 1～20h, optimum reacting time are 4～6h, obtain a kind of clay antiswelling agent for petroleum extraction after polyreaction finishes, and its molecular structure is that three side chains contain organic cationic polymkeric substance.
Clay antiswelling agent for petroleum extraction of the present invention is a kind of cation type polymer of three side chains, overcome the deficiency of the anti-swollen weak effect of straight chain cation type polymer, overcome of the perviousness injury of netted cation type polymkeric substance to reservoir, be a kind of heatproof, acidproof, oil resistant, the anti-persistent anti-clayswelling agent of swollen effect, be used for the different measure operation of natural petroleum gas field process, as the anti-swollen processing of the particularly new converted production well of water injection well, spearhead in the acidification to dispel block operation, acidizing fluid and subsequent fluid, and in the well control fluid of using during the old and new's well operations.
