Abstract

A sodium humate treating agent for drilling mud is disclosed. The treating agent comprises following components by weight: 20-30% of polymethylacrylic acid, 5-12% of potassium hydroxide and 5-15% of sodium humate, with the balance being water. The treating agent is used in petroleum drilling and geological core boring, and has characteristics of stable mud performance, anti-sloughing and wall-protecting properties for mudstone, safety in wells, high drilling speed, and simple and convenient using.

Description

technical field [0001] The invention relates to a mud treatment agent, in particular to a sodium humate drilling mud treatment agent. Background technique [0002] Currently, the sodium humate drilling mud treatment agent used in oil drilling and geological core drilling often has unstable mud properties and cannot have anti-collapse and wall protection effects on mudstone. Contents of the invention [0003] 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 mud performance is stable, and it has anti-collapse and wall protection effects on mudstone rocks, safety in the well, and high drilling speed. , easy to use. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is that a sodium humate drilling mud treatment agent is composed of the following components...
