Yellow or brown liquid aging 16h under the conditions of 80 DEG C, 160 DEG C, 220 DEG C of temperature obtained by embodiment, it is close
Degree is without significant change, and viscosity is compared with room temperature without rising appreciably, and the trend that viscosity with temperature increases and increases is small, temperature resistance stability
Good, temperature resistance is up to 220 DEG C.
The influence of the opposite grinding vector of yellow or brown liquid that one ~ example of testing example eight obtains, obtaining mill vector reduces
Rate % result is (listing the result of example one, example three, example five, example seven to explain) as shown in the table:
As can be seen from the test results, 0.4% ~ 1% embodiment liquid is added, metal mill vector 65% can be effectively reduced
More than, there is protective effect to intermetallic fretting wear.
The greasy property of yellow or brown liquid that one ~ example of testing example eight obtains obtains lubricating coefficient reduced rate % knot
Fruit is (listing the result of example one, example three, example five, example seven to explain) as shown in the table:
As can be seen from the test results, the lubricant effect in slurry is starched and aggravated to the embodiment liquid for being added 0.5% ~ 1% in base
Obviously, alternative or part substitution lubricant, reduces lubricant use cost；And its lubricating coefficient reduced rate is all larger than 80%, profit
Sliding drag-reduction effect is more preferably.
The limit wear-resistant pressure of yellow or brown liquid that one ~ example of testing example eight obtains, the sample-adding front and back limit are wear-resistant
Pressure increase value kg result is (listing the result of example two, example four, example six, example eight to explain) as shown in the table:
As can be seen from the test results, the embodiment liquid for being added 0.5% ~ 1% is starched and is aggravated in slurry in distilled water, base, is added
Limit wear-resistant pressure increase rate is larger before and after sample.
The compatibility of the yellow or brown liquid that also obtain to one ~ example of embodiment eight is tested, the results showed that, it removes
Outside the greasy property that live well slurry can be improved, other performances are starched almost without influence on well, compatibility is good.
Drilling fluid prepared by the present invention is adsorbed on casing and drilling rod surface by organic anion with Organic Friction-Reducing agent, is formed
One layer of high-intensitive extreme boundary lubrication film plays the role of wear-resistant.With anti-220 DEG C or more high temperature, compatibility it is good, without obvious viscosity effect,
The features such as scene is easy to use, maintenance is simple is suitable for high angle hole, horizontal well, highly dense in application, recommend dosage 0.5%-1%
