Description
Technical field
The present invention relates to a kind of assistant for drilling petroleum well filtrate reducer for drilling fluid and preparation method thereof, belong to oilfield chemical technology
Field.
Background technique
In drilling process, due to the effect of pressure difference, the moisture in drilling fluid inevitably passes through borehole wall leak-off to ground
In layer, drilling fluid dehydration is caused.As moisture enters stratum, in drilling fluid, clay particle, which is just attached on the borehole wall, forms " filter
Cake " forms a filter cake borehole wall.During the formation of the filter cake borehole wall, the excess moisture of leak-off, filter cake is blocked up, fine clay
Grain, which enters stratum etc. with moisture, can all influence normal drilling well, and damage to stratum.
Drilling fluid filtration is excessive, and Yi Yinqi shale expansion and collapsing cause hole instability.In addition, filter loss increases
While filter cake thicken, reduce hole diameter, cause biggish torque to the drilling tool of rotation, pumping and pressure wave are caused when making a trip
It is dynamic, easily cause differential sticking.Therefore, suitably controlling filter loss is one of important performance of drilling fluid.Determine filter loss size
Principal element be filter cake permeability.The high quality filter cake for how forming low-permeability prevents the further leak-off of drilling fluid,
It is one of the main problem to be considered during drilling fluid is prepared.
Fluid loss additive refers to the chemical agent that can reduce drilling fluid filtration.Fluid loss additive is mostly water soluble polymer chemical combination
Object, they can reduce the filter loss of drilling fluid by following approach.
Patent of invention CN101955565B is related to a kind of preparation method of loss additive for drilling fluid loss additive, including
Following steps: (1) raw material preparation: 2- acrylamide-2-methylpro panesulfonic acid, acrylamide, lignite, water, initiator and auxiliary material
Mass ratio be 2-3: 5-7: 7-10: 15-20: 0.1-0.2: 0.1-0.2: 25-30；(2) mother liquor is prepared: by 2- acrylamide
Base -2- methyl propane sulfonic acid and acrylamide are added separately in water, and then holding solution temperature is added in the case where being 50-70 DEG C
Lignite；(3) it polymerize: oxidizing initiators is added into mother liquor under stirring conditions, reacts 1h, add reduction initiator, instead
Answer 1h；(4) auxiliary material is added；(5) it dries, crushes: mixture obtained in step (4) is dried under conditions of 95-105 DEG C.
Loss additive for drilling fluid loss additive obtained has good thermal stability, and high temperature resistant property is good, can be effectively reduced
Filter loss, and there is clay inhibition, it is suitable for all kinds of water base drilling fluid systems, the especially high ground of high temperature clay content
Layer.
But the effect of the unstable clay of filtrate reducer for drilling fluid prepared with this technology, usually easily cause the mistake of clay
Degree dispersion, is unfavorable for drilling fluid rheology control.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of shale inhibition filtrate reducer for drilling fluid and preparation method thereof
, made fluid loss additive filtration reduction resistant to high temperatures is good, and thermal stability is good, and the inhibition that can have clay to disperse.
A kind of shale inhibition filtrate reducer for drilling fluid, the raw material including following mass parts: molecular weight 1,000,000 is below
