Drilling fluid defoaming agent

Abstract

The invention relates to the technical field of defoaming agents, and particularly relates a drilling fluid defoaming agent. The defoaming agent is prepared from the following components in parts by weight: 8-16 parts of calcium oxide, 4-8 parts of butadiene styrene rubber, 1-3 parts of a lubricating agent, 2-6 parts of polymethyl acrylate and 1-7 parts of metallic soap. The drilling fluid defoaming agent can be used for quickly completing the defoaming work to meet the production requirement when being used.

Description

technical field [0001] The invention relates to the technical field of defoamers, in particular to a drilling fluid defoamer. Background technique [0002] Drilling fluids need to use defoamers in the production process, but the current defoamers cannot meet the production needs. Contents of the invention [0003] In order to overcome the shortcomings of existing defoamers, the invention provides a drilling fluid defoamer. [0004] The technical solution adopted by the present invention to solve the technical problem is: a drilling fluid defoamer, comprising: 8-16 parts of calcium oxide, 4-8 parts of styrene-butadiene rubber, 1-3 parts of lubricant, poly 2-6 parts of methyl acrylate, 1-7 parts of metal soap. [0005] According to another embodiment of the present invention, it further includes that the optimal number of calcium oxide is 12 parts. [0006] According to another embodiment of the present invention, it further includes that the optimal number of parts of st...
