Abstract
The invention discloses a water retaining agent for liquid well cementing cement. The preparation method comprises the following steps: (1) putting 75.43 parts of distilled water in a reaction kettle, stirring and successively adding 17.5 parts of 2-methacrylamide-2-methyl propane sulfonic acid, 0.53 part of acrylamide and 0.7 part of maleic anhydride for abundant dissolution; (2) adding 3.8 parts of sodium hydroxide in the solution so that the pH value is regulated to 6-7, then adding 0.01 part of isopropanol, evenly stirring, and adding 0.175 part of ammonium persulfate in the kettle to stir for 5 minutes when heating to 48-50 DEG C; and (3) stopping stirring, then stirring and cooling when the temperature of the material liquid is raised to 80-90 DEG C, so as to react for 4 hours at the temperature of 80-85 DEG C, and inspecting by sampling so as to discharge the material. Because quadripolymer is added, the water retaining agent has the advantages of high temperature resistance and salt resisting property, thereby meeting the requirements of deep well and ultra-deep well cementing.
Description
Technical field:
The present invention relates to the composition that fixed well bore wall is used, particularly a kind of liquid cement-formation filtration control agent that under the situation of high temperature, high pressure and high salt, can satisfy reinforcing oil well cement slurry property needs that is applicable to.
Background technology:
Present oil-well cement filtrate reducer, as poly-ethanol, cellulose family and acrylamide copolymer etc., it is poor to exist anti-shear performance in actual applications, degraded is serious during pumping, anti-salt property is poor, to high volence metal ion sensitivity, poor heat stability, at high temperature easily decompose, can not satisfy the needs of cementing slurry performance under high temperature, high pressure and the high salt situation.
Summary of the invention:
The purpose of this invention is to provide a kind of liquid cement-formation filtration control agent that can satisfy cementing slurry performance need under high temperature, high pressure and the hypersaline environment.
Technical scheme of the present invention solves as follows, it includes following components by weight percent: 17.5 parts of 2-acrylamidos-2-methyl propane sulfonic acid, 1.75 parts of acrylamides, 0.53 part in vinylformic acid, 0.70 part of maleic anhydride, 3.80 parts in sodium hydroxide, 0.01 part of Virahol, 0.175 part of ammonium persulphate, 75.43 parts of distilled water, its preparation method is: (1) puts into reactor for 75.43 parts with distilled water earlier, begin to stir and add 2-methacryloyl amido-17.5 parts of 2-methyl propane sulfonic acids, 0.53 part of acrylamide, 0.7 part of maleic anhydride successively, make it abundant dissolving; (2) in above-mentioned solution, add 3.8 parts of sodium hydroxide, pH value is transferred to 6-7, add 0.01 part of Virahol again, stir, will stir 5 minutes in 0.175 part of ammonium persulphate adding still when being warming up to 48-50; (3) stop to stir after, when treating that feed temperature rises to 80-90 ℃, stir cooling again, make temperature be controlled under the 80-85 ℃ of condition reaction 4 hours, the inspection by sampling blowing that gets final product up to standard.This water retaining has high temperature resistant, salt resistant character by the adding of tetrapolymer, thereby has satisfied the needs of deep-well and ultra deep well well cementation.
Embodiment:
The present invention has following examples, feed composition includes 2-acrylamido-2-methyl propane sulfonic acid 1750 grams, acrylamide 175 grams, vinylformic acid 53 grams, maleic anhydride 70 grams, sodium hydroxide 380 grams, Virahol 1 gram, ammonium persulphate 17.5 grams, distilled water 7543 grams, its preparation method is: (1) puts into reactor with distilled water 7543 grams earlier, begins to stir, and add 2-methacryloyl amido-2-methyl propane sulfonic acid 1750 grams, 53 parts of grams of acrylamide, maleic anhydride 7 grams successively, make it abundant dissolving; (2) adding 380 gram sodium hydroxide in above-mentioned solution, the adjustment pH value transfers to and is 6-7, adds Virahol 1 gram then, stirs, and will stir 5 minutes in the ammonium persulphate 17.5 gram adding stills when being warming up to 48-50 ℃; (3) stop to stir after, when treating that feed temperature rises to 80-90 ℃, stir cooling again, make temperature be controlled under the 80-85 ℃ of condition reaction 4 hours, the inspection by sampling blowing that gets final product up to standard.General usage quantity is the 3-6% of grout, and it is wide to have use range, at oil well cements at different levels, can both use in the grout of any proportion, and multiviscosisty transit time is short, near the right angle multiviscosisty, and cement strength is had no adverse effects.Because in 2-acrylamido-2-methyl propane sulfonic acid molecular structure, have the rigidity side group, can effectively increase sterically hinderedly, improve the molecule chain rigidity; Sulfonic group makes sulfonic group because of more stable more greatly because of, electric density, and is insensitive to the outer cationic attack.So this polymkeric substance high-temperature resisting and salt-resisting performance is stronger.In order to guarantee the rheological of grout, use vinylformic acid, maleic anhydride, contain carboxyl in their molecular structures, can play and disperse and hydration, carry out rheology according to the grout situation and regulate, add acrylamide, have adsorption, a large amount of molecular adsorption are at cement surface, and building bridge forms certain reticulated structure, dosage is 3-6%, can control the fluid loss of grout effectively.
