The self-overflowing sealant of the invention is capable of coating the aggregates with the cement and the expanding agent, and solves the problems of own strength, fragility and interface bonding strength of such a lost circulation additive after being solidified in water.
Description
Technical field
The present invention relates to close sealing agent from overflowing, sealing agent is closed in overflowing certainly that particularly oil of fissured formation (gas) well leak stopping and well workover, construction work and civil engineering work waterproof and leak stopping are used.
Background technology
Leakage is the FAQs in the petroleum gas exploitation, is having a strong impact on carrying out smoothly of drilling well work.If leakage deal with down hole problem or Serious Accidents such as causing well slough, bit freezing, blowout probably improperly, more very can cause well to be scrapped and cause the tremendous economic loss.Patching materials is as requisite material in the drilling well leak-proof leak-stopping, and its performance directly affects the quality of drilling well leak-proof leak-stopping effect.In plugging operations; When cement, gelling class plugging agent are met water wherein functional salt and admixture is very easily diluted washes away, cause that it is poor in the target location presence, not firm with the interface bonding, the little contraction of process of setting causes that plugging effect obviously descends under its counterpressure, effectively the leak stopping phase shortens, the loss thing makes troubles to follow-up construction; Hydroscopic high-molecular resin plugging agent cost is high, in plugging operations, because the water-absorbing resin rate of expansion is too fast, is not transported to before the target location water-swelling closed operation mouth, and its plugging operations can not effectively be accomplished.Even be sent to the target location, because self does not have cohesive force or cohesive force smaller with the interface, when running into, also can dilutedly wash away than big flood, cause plugging effect to reduce or lose.
One Chinese patent application 95113228.8 discloses a kind of compound leakage stop agent for drilling; Formulation weight per-cent is: plant granulated material 40～60%, plasticity flaky material 15～20%, filamentary material 18～35%; SEPIGEL 305 2～10%, MOX toughener 4～8%.Plant granulated material, plasticity flaky material and filamentary material are pulverized, are sieved and be selected, mix with macromolecular material and toughener then, are mixed with plugging agent in proportion.One Chinese patent application 02121292.9 discloses a kind of heat-resistant salt-resistant type water-absorbing resin; Comprise in vinylformic acid, acrylic amide and the cationic monomer terpolymer and be added with mineral filler with laminate structure; Acrylic amide is 10～70% of a monomer total amount; The mineral filler of laminate structure is 10～150% of a monomer total amount, and cationic monomer is 5～15% of a monomer total amount, can under 70～150 ℃, the situation of 5000～100000PPm salinity, keep swelling property and shrink-proof or structure deteriorate.One Chinese patent application 200910216736.1 discloses a kind of drill-feeding plugging agent of oil-gas exploration and development; This plugging agent comprises 2-acrylamido-2-methyl propane sulfonic acid sodium, acrylic amide, initiator and linking agent; By mass percentage: water accounts for 78%, and 2-acrylamido-2-methyl propane sulfonic acid sodium and acrylic amide account for 20%, and initiator accounts for 0.5%; Linking agent accounts for 1.5%, and the mass ratio of 2-acrylamido-2-methyl propane sulfonic acid sodium and acrylic amide is 1: 4～1: 6.Suction was fast and body intensity is low when the common defects of these three patented claims was leak stopping.
One Chinese patent application 200910216736.1 discloses a kind of efficient plugging agent material, and its component and mass percent are: sulphoaluminate cement clinker 86～92%, anhydrite 4～8%; Wingdale 3～6%; Fluidizer 0.02～0.05%, accelerator for hardening 0.06～0.15%, polypropene staple 0.12～0.15%; It is fast to have gel solidification, and the impermeabilisation rank is high.One Chinese patent application 201010034420.3 discloses a kind of auto-waterproof bridging particle, and its component and mass parts ratio are: 20～85 parts of aluminosulfate cements, 5～26 parts of ferro-aluminate cements; 5～20 parts of aluminas; 3～10 parts of gypsum classes, 2～10 parts of microdilatancy components, 0～5.0 part of gel time adjustment agent; 0～3.0 part of 0～1.0 part of fluidizer and caking agent have fast blockage, water-swellable, penetrant crystalline, micro-cracks self-healing and permanent waterproof function.The common defects of these two patented claims be plugging agent when meeting water wherein functional salt and admixture is very easily diluted washes away, cause its in the target location presence poor, not firm with the interface bonding.
Summary of the invention
The problem that invention will solve
Problem to cement, gelling class plugging agent and the existence of hydroscopic high-molecular resin plugging agent; When the present invention will solve cement, gelling class plugging agent and meets water wherein functional salt and admixture is very easily diluted washes away, cause that it is poor in the target location presence, not firm with the interface bonding, the little contraction of process of setting causes that plugging effect obviously descends under its counterpressure, the effective problem that shortens of leak stopping phase.The present invention also will solve the hydroscopic high-molecular resin plugging agent in plugging operations, because the water-absorbing resin rate of expansion is too fast, is not transported to before the target location water-swelling closed operation mouth, the problem that its plugging operations can not effectively be accomplished.
The present invention will solve this type of plugging agent and in water, solidify the problem of the bonding strength at self intensity, fragility and interface afterwards.
