Description
Technical field
The present invention relates to a kind of preparation method of oilfield drilling liquid fluid loss agent, especially use the preparation method of the high temperature resistant drilling fluids fluid loss agent of oxidation inhibitor blending and modifying vinyl monomer-grafted starch.
Background technology
Starch is cheap, the abundant also readily biodegradable in source.Rise since the eighties in 20th century, starch and derivative thereof just are used as the Environment-protecting Drilling Fluids fluid loss agent and at home and abroad are widely used.Yet starch seldom directly is used as filtrate reducer for drilling fluid, usually will pass through before use pregelatinated, etherificate or three kinds of mode modifications of grafting.
In early days, pregelatinated technique is more convenient and cost is low, thereby is used widely.Starch is generally processed under alkalescence or acidic medium, and purpose is that the hydrogen bond of breaking between macromole obtains the pregelatinated product.Because it has weak resistibility to heat and bacterium, it uses the DWSW liquid system that only is confined to lesser temps.Etherification starch, the hydroxyl that refers on the starch is replaced by ehter bond.Commonly under alkaline condition, Mono Chloro Acetic Acid and starch reaction prepare carboxymethyl starch.In addition, also have the products such as 2-hydroxyl-3-sulfo-propyl group starch, hydroxyethylamyle and hydroxypropylated starch.The ehter bond substitution value is larger, more is conducive to fall leak-off, the industrial starch that often prepares high degree of etherification with the most of water of alcohol replacement as reaction medium.Graft starch refers to that vinyl monomer is grafted on the starch polymer in the presence of initiator, the method is more easily carried out molecular designing, convenient at the starch polymer various functional groups of introducing and raising molecular weight product, reach the purpose of artificial ruling molecular structure and performance.And product can not carry out aftertreatment.
With regard to use temperature, no matter above-mentioned the sort of treated starch, their inefficacies of in surpassing 120 ℃ drilling fluid environment, will more or less degrading.Even if also just 130～140 ℃ of the high temperature resistance starch operating limit temperature of better performances.
Summary of the invention
The object of the invention is to overcome above-mentioned prior art not enough, provide and still have excellent filtrate loss controllability under a kind of drilling fluid environment that is used in greater than 150 ℃ of high temperature, and anti-salt is produced simply to saturated, need not the preparation method of the high temperature resistant drilling fluids fluid loss agent of aftertreatment.
Solution of the present invention is: a kind of preparation method of high temperature resistant drilling fluids fluid loss agent is characterized in may further comprise the steps:
A, starch and water are added in the reactor, under 70～100 ℃, stir;
B, until the starch aqueous dispersion become transparent after, cool to 35～65 ℃, add initiator, initiator concentration is 0.001～0.05 mol/L after adding;
C, adding vinyl monomer continued stirring reaction 2.5～7 hours;
D, temperature of reaction system is down to room temperature, adds oxidation inhibitor and pH value conditioning agent, stir;
Wherein: the mass ratio of starch and vinyl monomer is 0.5～1:1, the mass ratio that water and starch add vinyl monomer is 4～19:1, the mass ratio that oxidation inhibitor and starch add vinyl monomer is 0.1～0.7:1, and the dosage of pH value conditioning agent is as the criterion to regulate fluid loss agent pH value to 7～10.
In the solution of the present invention, starch is the mixture of W-Gum or yam starch or sweet potato starch or above-mentioned arbitrary proportion.
In the solution of the present invention, initiator is the mixture of ammonium persulphate or Potassium Persulphate or ceric ammonium nitrate or ammonium cerous sulfate or above-mentioned arbitrary proportion.
In the solution of the present invention, vinyl monomer is the mixture of vinylformic acid or acrylamide or 2-acrylamide-2-methyl propane sulfonic or above-mentioned arbitrary proportion.
In the solution of the present invention, oxidation inhibitor is the mixture of S-WAT or sodium bisulfite or Sodium Pyrosulfite or thanomin or above-mentioned arbitrary proportion.
In the solution of the present invention, pH value conditioning agent is the mixture of sodium hydroxide or potassium hydroxide or ammoniacal liquor or above-mentioned arbitrary proportion.
Advantage of the present invention: the present invention is on the basis of the composition and engineering of the monomer-grafted starch of Optimization of Ethylene base, adding oxidation inhibitor carries out blending and modifying and prepares fluid loss agent, thereby reaches the purpose that suppresses starch high temperature degradation (the especially fracture of ehter bond in the starch polymer).The high temperature resistant drilling fluids fluid loss agent that utilizes the inventive method to obtain is biodegradable, still has excellent filtrate loss controllability under the drilling fluid environment of 150～170 ℃ of high temperature, and anti-salt is to saturated.The inventive method is simple to operate, and is low to equipment and environmental requirement, need not aftertreatment, easily realizes industrialization.
