Abstract
The invention relates to a method for preparing a vinyl sulfonate polymer drilling fluid treating agent, which belongs to the technical field of oil drilling oilfield chemistry water soluble macromolecule material synthetic preparation method. The method comprises the following steps: according to a certain weight ratio, 2-acrylamide-2-methylpropanesulfonic acid, acrylamide and acrylic acid are added to a reactor filled with water to prepare aqueous solution, sodium hydroxide is added to the aqueous solution to control the pH value of the polymer system to between 9.0 and 11.0, and an initiator is added for polyreaction, the initial temperature of the polyreaction is between 30 and 60 DEG C, and the polyreaction time is 1 to 2 hours; and the obtained products are sheared to be particle-shaped, dried at a temperature of between 100 and 120 DEG C and crushed to obtain the vinyl sulfonate polymer drilling fluid treating agent. The treating agent is mainly applied to drilling liquid and completion fluid, and can also be used as filter loss reducing agent and high-temperature slow release agent for oil well cement, and flocculant for oil well water shut-off and water treatment.
Description
Technical field: the present invention relates to a kind of preparation method of vinyl sulphonate polymer drilling fluid finishing agent, belong to the synthetic class preparation method technical field of petroleum drilling oilfield chemistry water-soluble high-molecular material.
Background technology: from the development of additive for drilling fluid, it is twentieth century the 1970s and 1980s that China's additive for drilling fluid develops period rapidly, formed therebetween with acrylamide, acrylic-multipolymer is the polymer class treatment agent of representative, and formed the corresponding polymer drilling fluid system, thereby promoted the progress of drilling fluid Technology.Use so far from the eighties in 20th century, the heat and salinity tolerance performance of polymer class treatment agent is not very desirable always, especially under the situation of high temperature composite salt, it is relatively poor that the raising drilling fluid glues the ability of cutting, reduce drilling fluid filtration, and this just makes polymkeric substance demonstrate its distinctive limitation.
Summary of the invention: the purpose of this invention is to provide a kind of preparation method who is easy to the vinyl sulphonate polymer drilling fluid finishing agent of large-scale industrial production, to solve polymkeric substance under the high temperature and high salt situation, improve that drilling fluid is sticking cuts, reduces the problem that drilling fluid filtration, flocculation, bag are suppressed the pulping weak effect.
The present invention comprises following steps: with 2-acrylamido-2-methyl propane sulfonic acid, acrylamide and vinylformic acid by (5～5): (1～8): the mass ratio of (4～10) adds in the reactor that fills water and is mixed with the aqueous solution, the pH value that adds sodium hydroxide controlled polymerization system in the aqueous solution is 9.0～11.0, add initiator then and carry out polyreaction, the starting temperature of polyreaction is 30～60 ℃, polymerization time is 1～2 hour, products therefrom is cut into particulate state, in 100～120 ℃ of oven dry down, pulverize and be vinyl sulphonate polymer drilling fluid finishing agent.
Product of the present invention has the dehydration of falling, flocculation, bag and is suppressed over-all propertieies such as pulping, have stronger temperature resistant antisalt and fall filtration capacity, Heat stability is good, compatibleness is good, shown better comprehensive performance, had stronger carrying and stickingly cut effect in drilling fluid, the present invention is mainly used in drilling fluid and the well finishing liquid, simultaneously also can be used as cement filter loss-reducing agent for oil well and high temperature retarder, and oilwell water shutoff and water treatment flocculant etc.
