Abstract
The invention discloses a preparation method of a ternary polymer filtrate loss reduction additive for oil well cement. The preparation method comprises the following steps: firstly preparing 8.4 parts of deionized water and 1 part of ammonium persulfate into an initiating agent solution for later use; then adding 639.6 parts of the deionized water to a reaction kettle, sequentially adding 139 parts of 2-acrylamido-2-methyl propanesulfonic acid, 20.7-27.5 parts of acryloyl morpholine, 9 parts of acrylic acid, 4.4 parts of isopropanol and 0.1 part of light calcium carbonate during stirring for uniform dissolution and mixing; regulating a PH value to 4-5 by using 79 parts of 40% caustic soda solutions, and controlling temperature below 40 DEG C at the same time; increasing the temperature of a material inside the reaction kettle to 58-60 DEG C, then slowly adding a spare initiating agent solution, and fixing reaction temperature at 79-83 DEG C for continuous reaction, wherein the reaction is lasted for 240 minutes by counting time from adding the initiating agent solution; and reducing to room temperature, and stopping stirring. The preparation method disclosed by the invention can be used for preventing the phenomenon of reversion of cement thickening time and has no toxic effect on contacted people.
Description
Technical field:
The present invention is the preparation method of the environment-friendly type oil well cement ter-polymers water retaining that a kind of poisonous material is made.
Background technology:
Current oil well cement paste polymkeric substance water retaining, be that main raw material is made with acrylamide, with the water retaining that this raw material is made, though have good filtrate-loss control energy owing to there being the existence of amide group, but easily decompose when high temperature, cause the grout high temperature thickening time long, the low temperature thickening time is short, thickening time hangs upside down, and affects cementing operation quality.This material simultaneously in this raw material has neurotoxic effect to exposed population group, and serious even causes genetic mutation.
Summary of the invention:
The object of this invention is to provide one not only filtrate-loss control, temperature resistance, anti-salt property can also effectively avoid well cement slurry thickening time inversion phenomenon occurs, and the preparation method of oil well cement ter-polymers water retaining to exposed population group's toxicological harmless effect.
Technical scheme of the present invention completes as follows, it includes following components by weight percent: 2-acrylamido-2-methyl propane sulfonic acid 139 parts, acryloyl morpholine 20.7 ~ 27.5 parts, 9 parts, vinylformic acid, Virahol 4.4 parts, deionized water 748 parts, concentration is the caustic soda soln 79 parts of 40%, ammonium persulphate 1.0 parts, light calcium carbonate 0.1 part; Its preparation method is: 1. first taking out 8.4 parts of deionized waters and ammonium persulphate, to be mixed with initiator solution for subsequent use; Again remaining deionized water is dropped in reactor, open and stir, add 2-acrylamide-2-methylpro panesulfonic acid successively, acryloyl morpholine, vinylformic acid, Virahol, light calcium carbonate dissolve and mix; 2. by concentration be 40% caustic soda soln adjustment still in the pH value of mixed liquor be 4 ~ 5, period, control temperature was below 40 DEG C; 3. material in reactor is warming up to 58 ~ 60 DEG C, then initiator solution for subsequent use is slowly added, rapid stirring stop after 2 minutes stir etc. to be polymerized, open when temperature of charge rises to 77 ~ 80 DEG C in observing response still and stir, reaction is continued at 79 ~ 83 DEG C by constant for temperature of reaction, timing from adding initiator solution, reaction continues 240 minutes, is down to room temperature and stops stirring.
Water retaining of the present invention not only has the filtrate-loss control identical with containing acrylamide water retaining, the performance of temperature resistance, anti-salt, also avoid the generation of cement slurry thickening time inversion phenomenon, and slurry flowing performance-changing is also significantly improved, to exposed population group's toxicological harmless effect.
Embodiment:
The present invention has following examples:
Embodiment 1:
1. first taking out 8.4kg deionized water and 1kg ammonium persulphate, to be mixed with initiator solution for subsequent use; Again the deionized water of 739.6kg is dropped in reactor, open and stir, add 139kg2-acrylamide-2-methylpro panesulfonic acid successively, 20.7kg acryloyl morpholine, 9kg vinylformic acid, 4.4kg Virahol, 0.1kg light calcium carbonate dissolve and mix; 2. being about 79kg with the caustic soda soln that concentration is 40%, to adjust the pH value of mixed liquor in still be 4 ~ 5, and period, control temperature was below 40 DEG C; 3. material in reactor is warming up to 58 ~ 60 DEG C, then initiator solution for subsequent use is slowly added, rapid stirring stop after 2 minutes stir etc. to be polymerized, open when temperature of charge rises to 77 ~ 80 DEG C in observing response still and stir, reaction is continued at 79 ~ 83 DEG C by constant for temperature of reaction, timing from adding initiator solution, reaction continues 240 minutes, stops stirring being down to room temperature.
Embodiment 2
