Abstract

The invention discloses an emulsified residual oil type lubricant for a drilling fluid and a production process thereof. The emulsified residual oil type lubricant for the drilling fluid comprises the following components in parts by weight: 40 to 60 parts of residual oil, 10 to 20 parts of No.15 technical white oil, 10 to 20 parts of paraffin, 20 to 30 parts of an anti-freezing agent, 1 to 5 parts of sorbitan oleate and 1 to 5 parts of sulfonic acid. The emulsified residual oil type lubricant prepared by adopting the production process is used in the drilling fluid and has the advantages of low friction resistance, good immersion effect and high anti-collapse performance; and by adopting the emulsified residual oil-type lubricant, the quality of mud cakes can be effectively improved.

Description

Technical field [0001] The invention involves a production process for a lubricant for drilling liquid and this lubricant. Background technique [0002] During the drilling process, when the shaft or oblique well is determined, a certain amount of crude oil or residue products need to be added to the drilling solution as a lubricant.The residue oil is the residual oil obtained by crude oil after decompression and distillation. The color is dark and sticky, and the nature is semi -solid. The properties are related to the nature of crude oil.Crude oil or emulsification slag oil products are used as a drilled lubricant. When used directly, the anti -collapse performance and abrasion resistance effect is poor, and there is no obvious effect on changing the quality of the mud cake;Oil into a solid shape, it cannot be used. Invention content [0003] The technical problem resolved by the present invention is to provide a kind of lacta lubricant that provides milling resistance and goo...
