for a linear or planar leakage area where the leakage point is difficult to accurately find, solid organic substance powder capable of being dissolved in water is flatly paved in the leakage area, so that the solid organic substance permeates into the tiny leakage point of the leakage area, the solid organic substance is dissolved in the water and forms a solution with cohesiveness and adhesiveness in the leakage point, and soil, fine sand or solid impurities in the leakage point are adhered to block the leakage point.
In the method, the water-soluble solid organic substance is one or a mixture or copolymer of two or more of polyvinyl alcohol, water-absorbent resin, sodium polyacrylate cross-linked copolymer, polyacrylate, polyacrylamide, polyethylene oxide, polyethylene glycol, sodium polyacrylate, sodium carboxymethylcellulose, hydroxypropyl methylcellulose and cellulose ether;
in the method, when the solid organic substance capable of being dissolved in water is used, the solid organic substance is sealed and packaged by a packaging bag, the packaging bag is taken to a leakage point, the packaging bag is opened, and the opening of the packaging bag is aligned with the leakage point so that the solid organic substance capable of being dissolved in water can penetrate into the leakage point;
in the method, before the solid organic substance capable of being dissolved in water is used, the solid organic substance is dissolved in water to prepare a solution with cohesiveness and adhesiveness, the solution is hermetically packaged by a packaging bag and is brought to a leakage point, the packaging bag is opened, and the opening of the bag is aligned with the leakage point so that the solution can penetrate into the leakage point;
in the method, after the solution with the caking property and the adhesion property permeates the leakage point, fine sand is added to the leakage point, so that the fine sand in the leakage point is adhered to block the leakage point.
In the method, for a linear or planar leakage area in which a leakage point is difficult to accurately find, the solid organic substance capable of dissolving in water is dissolved in water to prepare a solution with cohesiveness and adhesiveness, the solution is sealed and packaged by a packaging bag and is brought to the leakage point, fine sand is paved on the leakage area to ensure that at least part of the fine sand permeates into the leakage point, the packaging bag is opened, a bag opening is aligned with the leakage area to ensure that the solution permeates into the leakage point, then the fine sand is paved on the leakage area to ensure that the fine sand permeates into the leakage point again, namely the fine sand is added to the inner side and the outer side of the solution with cohesiveness and adhesiveness, so that the solution can conveniently adhere soil, fine sand or solid impurities in the leakage point, the loss of the solution is reduced, and the plugging effect is improved.
Compared with the prior art, the method utilizes the characteristic that solid organic substances capable of dissolving in water can form solution with cohesiveness and adhesiveness after being dissolved in water, and can be used for plugging the leakage points of the reservoir, so that fine sand, soil or other solid substances in the leakage points can be effectively and quickly adhered, the leakage points are plugged internally, even if most of the cohesiveness and adhesiveness solution is lost along with the lapse of time, the stability of plugging can be improved along with the continuous increase of sand and soil entering gaps, the leakage can be avoided from happening again, the plugging effect is good, the method is very convenient to control the leakage of the reservoir, the construction is simple, the cost is extremely low, and the method is suitable for popularization and application.

The cellulose can be dissolved in water, dilute alkali solution and organic solvent after etherification, and has thermoplasticity.
Example 5
The embodiment provides a method for treating leakage of water engineering, which comprises the following specific steps:
for a linear or planar leakage area where a leakage point is difficult to accurately find, firstly, dissolving sodium polyacrylate in water to prepare a solution with cohesiveness and adhesiveness, hermetically packaging the solution by using a packaging bag, carrying the solution to the leakage point, paving fine sand in the leakage area to enable at least part of the fine sand to penetrate into the leakage point, then opening the packaging bag, aligning a bag opening with the leakage area to enable the solution to penetrate into the leakage point, enabling the sodium polyacrylate solution to adhere soil, fine sand or solid impurities in the leakage point to block the leakage point, and paving the fine sand in the leakage area after using the sodium polyacrylate solution to enable the fine sand to penetrate into the leakage point again, namely adding the fine sand into the inner side and the outer side of the sodium polyacrylate solution, so that the adhesion of the fine sand is facilitated, and the blocking effect is improved.
The sodium polyacrylate is a new type functional high molecular material and important chemical product, its solid product is white or light yellow block or powder, and its liquid product is colorless or light yellow viscous liquid. Is prepared from acrylic acid and its esters through aqueous solution polymerization. Odorless, and can be dissolved in sodium hydroxide water solution and precipitated in calcium hydroxide, magnesium hydroxide, etc. It is commonly used as water treatment agent, brine refining and latex thickening, and also can be used for food viscosity increasing and emulsification.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
