Abstract
The invention relates to a flocculation-type composite plugging agent. The flocculation-type composite plugging agent is mainly composed of bentonite, urea-formaldehyde resin, potassium metasilicate, sodium hydroxide, magnesium oxide, calcium carbonate, a plasticizer, a curing agent, etc. The flocculation-type composite plugging agent has effects of restoring and coagulating cracks, and is especially applied in plugging low-pressure fragmentation stratigraphic architectures, reef limestone stratigraphic architectures and fracture-type stratigraphic architectures.
Description
Technical field
The present invention relates to a kind of fast plugging agent, belong to technical field of fine chemical preparations.
Background technology
Lasting exploitation along with hypogee, city, civil air defense constructions and installations and the construction of large-scale sewage network, problem owing to geology reason, construction technology, construction material, the seepage that occurs in the various construction processs, scurry that layer, Bian Shui, end Shuitu advance, cross early leaving or water logging, contradiction such as cave in and problem progressively manifest, whole construction progress and construction quality have been had a strong impact on, so, research and the application of various kind plugging agents is subjected to day by day the great attention of each research institution.Develop chemical gelling leak stopping methods such as the leak stopping of bridge slurry, bridging plug leak stopping, the leak stopping of diesel oil bentonite slurry in the market, though also play a role, had following shortcoming or deficiency: when blocking construction, can't condense and repair the leakage stratum; For ravelly ground, the easy stratum of collapsing, particularly during the stratum of low pressure cementing properties difference, can not condense to ravelly ground reparation; Behind the blocking construction, bearing capacity is low, and plugging effect is poor, causes the repeated multiple times leak stopping.Also have some as water glass high strength chemistry water blockoff, polymkeric substance water blockoff envelope scurry, multinomial chemical plugging technology such as superpolymer single-fluid process chemical water plugging.These water-plugging techniques have played vital role in hypogee, city, civil air defense constructions and installations and large-scale sewage network construction, yet water glass high strength chemistry water-plugging technique construction technology complexity, difficulty is big, danger is bigger, and the plugging agent consumption is big, long construction period, shutoff safety coefficient are low; It is shorter to be with the urethane manthanoate that the cyanogen of main body composition coagulates the blocking agent gel time, though consumption is few, and the plugging strength height, the plugging technology complexity, dangerous higher, shutoff thickness is little, should not adopt during big section shutoff.Therefore, press for research and release a kind of novel plugging agent, to satisfy the plugging agent of various shutoff requirements.
Summary of the invention
Purpose of the present invention will provide a kind of effects such as reparation, the crack of condensing that have exactly, especially is applied to the compound plugging agent of flocculation type of the shutoff of low pressure broken formation structure, reef limestone stratal configuration and slit formation stratal configuration.
The present invention is achieved through the following technical solutions: it is characterized in that the compound plugging agent of this flocculation type mainly by: wilkinite, urea-formaldehyde resin, potassium silicate, sodium hydroxide, oxygen magnesium, calcium carbonate, softening agent, solidifying agent etc. are formed.
The compound plugging agent of a kind of flocculation type by its weight ratio is: wilkinite 1～6%; Urea-formaldehyde resin 0.5～0.75; Potassium silicate 6～8; Sodium hydroxide 0.1～0.5; Magnesium oxide 5～8; Calcium carbonate 15～20; Softening agent 2～4; Solidifying agent 1～5 composition such as grade.
The compound plugging agent of a kind of flocculation type.Its softening agent is polypropene staple.
Embodiment
(1) takes by weighing wilkinite 4% by weight; Urea-formaldehyde resin 0.75; Potassium silicate 6; Sodium hydroxide 0.3; Magnesium oxide 6; Calcium carbonate 15; Softening agent 2; Solidifying agent 4, standby.
(2) preparation method
Each component batching is added in the reactor, after fully mixing, leave standstill 1h, take out and carry out on-the-spot shutoff.
Claims (3)
1. compound plugging agent of flocculation type, the compound plugging agent of this flocculation type mainly by: wilkinite, urea-formaldehyde resin, potassium silicate, sodium hydroxide, oxygen magnesium, calcium carbonate, softening agent, solidifying agent etc. are formed.
2. according to the compound plugging agent of right 1 described a kind of flocculation type, by its weight ratio be: wilkinite 1～6%; Urea-formaldehyde resin 0.5～0.75; Potassium silicate 6～8; Sodium hydroxide 0.1～0.5; Magnesium oxide 5～8; Calcium carbonate 15～20; Softening agent 2～4; Solidifying agent 1～5 composition such as grade.
3. according to right 1, the compound plugging agent of 2 described a kind of flocculation types, its softening agent is polypropene staple.
