Abstract

The technical scheme adopted by the invention provides an efficient slurry treating agent. The efficient slurry treating agent is composed of the following components by weight percent: 20-30% of polymethylacrylic acid, 5-12% of sodium hydroxide, 5-15% of sodium humate and the balance of water. The efficient slurry treating agent is used in petroleum drilling and geological core drilling, efficient slurry is stable in performance and has the effects of preventing collapse and protecting wall on shale rock, the inside of a well is safe, the drilling rate is high, and use is simple and convenient.

Description

[0001] technical field [0002] The invention relates to a mud treatment agent, in particular to a high-efficiency mud treatment agent. Background technique [0003] Existing mud treatment agents are used in oil drilling and geological core drilling, and often have unstable mud properties, and cannot have anti-collapse and wall protection effects on mudstone. Contents of the invention [0004] Aiming at the shortcomings and deficiencies of the existing technology, the technical problem to be solved by the present invention is that, when used in oil drilling and geological core drilling, the high-efficiency mud has stable performance, has anti-collapse and wall protection effects on mudstone rocks, and is safe in the well. High and easy to use. [0005] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is that a high-efficiency mud treatment agent is composed of the following components by weight percentage: 2...
