Abstract

The invention relates to the technical field of chemical materials, and specifically relates to a plugging agent with a good curing effect. The plugging agent is composed of the following components in percentage by weight: 25 to 44% of curable material (blast furnace slag), 11 to 22% of acid-soluble material (calcium carbonate), 13 to 19% of fiber materials (asbestos fiber, cotton fiber, or corn core), and 5 to 22% of high fluid loss material (diatomite or fly ash). The application of the provided plugging agent is flexible, and the plugging effect is prominent.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a plugging agent with good curing effect. Background technique [0002] Oil well exploitation is a dangerous operation, not to mention the high technical content required by itself, and a more serious problem is well leakage. Lost wells can cost a lot of money, and serious ones can even result in death. Today, leak stoppers on the market can solve this problem to a certain extent. However, most of these plugging agents cannot be used alone. In order to exert their maximum effect, some other composite materials must be added, which means that the cost is relatively high. Contents of the invention [0003] The object of the present invention is to provide a leak-stopping agent with good curing effect, flexible use and obvious leak-stopping effect. [0004] The technical solution adopted in the present invention is a plugging agent with good curing effect, and the ma...
