Abstract
The invention provides the preparation method of drilling fluid fluid lubricant, the base oil for being 60-80% by mass percentage, and mass percentage is the extreme pressure agent of 20-40%, and mass percentage is the surfactant of 1-5%, and 50-80 DEG C of heating mixes.The invention also discloses drilling fluid fluid lubricant, is prepared by the above method.The invention has the advantages and positive effects of: creating the obtained drilling fluid fluid lubricant of preparation through the invention.Good water solubility, fluorescence grade are low, and greasy property outstanding actually uses 1-1.5%, and lubricating coefficient reduced rate is up to 80% or more.Can temperature resistance to 230 DEG C, can in saturated salt-water drilling fluid normal use.It is particularly suitable for the drilling fluid demand of high deep-well.
Description
Technical field
The invention is related to drilling technology field, more particularly to drilling fluid fluid lubricant and preparation method thereof.
Background technique
The most important function of drilling fluid first is that cooling and lubrication drilling tool.If drilling fluid lubricating poor performance, will make to bore
Frictional force between column and the borehole wall surges, and moment of torsion should become very big, causes bit freezing, or even twist off drilling rod.When well deflection,
This situation is more serious.It is also possible to bring a series of other problems in addition, drilling fluid lubricating performance is bad, causes many undergrounds multiple
Miscellaneous situation, and reduce drilling speed and increase shaft building cost.Improving drilling fluid lubricating performance mainly has two approach, one is using oil
Base mud, especially water-in-oil emulsion mud, the second is by lubricating additive is added.
Vegetable oil mineral oil etc. makes drill string and the rock borehole wall by forming adsorbed film in metal rock and clay particle surface
The solid friction that contact or moisture film contact generate is changed into the friction between activating agent non-polar end or between oil film, or passes through
The non-polar end of surfactant adsorbs one layer of oil film again, so that the frictional resistance between drill string and the borehole wall be made to substantially reduce.It is right
For vegetable oil lubricating agent, ester bond not only has intrinsic lubricity in lubricant molecule, but also vegetable oil can be promoted to adsorb
Lubricating action is played to metal surface.
Summary of the invention
The problem to be solved by the invention is to provide drilling fluid fluid lubricants and preparation method thereof, are particularly suitable for
The drilling fluid demand of high deep-well.
In order to solve the above technical problems, the invention the technical solution adopted is that: the system of drilling fluid fluid lubricant
Preparation Method, the base oil for being 60-80% by mass percentage, mass percentage are the extreme pressure agent of 20-40%, quality percentage
Content is the surfactant of 1-5%, and 50-80 DEG C of heating mixes.
Preferably, the synthesis of the extreme pressure agent use outer circulation reaction under high pressure technology, using oleic acid as host agent, with sulfur-bearing, phosphorus,
The compound of chlorine is adjuvant, and reaction is made.
Preferably, the raw material of the extreme pressure agent include Vegetable oil, elemental sulfur, triethanolamine, phosphoric acid, ethanol amine,
Boric acid.
Preferably, the base oil for being 65-75% by mass percentage, mass percentage are the extreme pressure agent of 25-35%,
Mass percentage is the surfactant of 2-4%, and heating mixes.
The invention also discloses drilling fluid fluid lubricant, is prepared by the above method.
The invention has the advantages and positive effects of: creating the obtained drilling fluid liquid of preparation through the invention
Body lubricant.Good water solubility, fluorescence grade are low, and greasy property outstanding actually uses 1-1.5%, and lubricating coefficient reduced rate reaches
80% or more.Can temperature resistance to 230 DEG C, can in saturated salt-water drilling fluid normal use.It is particularly suitable for the brill of high deep-well
Well liquid demand.
Specific embodiment

In another embodiment of the invention, the base oil for being 65-75% by mass percentage, quality percentage contains
Amount is the extreme pressure agent of 25-35%, and mass percentage is the surfactant of 2-4%, and heating mixes.
The invention also discloses drilling fluid fluid lubricant, is prepared by the above method.By the invention
The property of drilling fluid index for the drilling fluid fluid lubricant being prepared is as shown in the table.
The physical and chemical index for the drilling fluid fluid lubricant being prepared by the invention is as shown in the table.
| Project | Index |
| Appearance | Brownish black working fluid |
| Density g/cm3 | 0.80~1.0 |
The drilling fluid fluid lubricant good water solubility that is prepared by the invention, fluorescence grade are low, profit outstanding
Slip can actually use 1-1.5%, and lubricating coefficient reduced rate is up to 80% or more.Can temperature resistance to 230 DEG C, can be in saturated brine
Normal use in drilling fluid.It is particularly suitable for the drilling fluid demand of high deep-well.In addition, this product may be directly applied to various water
In base drilling fluid system.There are good compatibility, general dosage 1.0-1.5% with a variety of inorganic agents.
The embodiment of the invention is described in detail above, but the content is only the preferable of the invention
Embodiment should not be considered as limiting the scope of the invention.It is all according to equivalent change made by the invention range with
Improve etc., it shall still fall within the scope of this patent.
