Abstract
The invention relates to an oil-based drilling fluid used in oil field drilling, in particular to a polymer fluid loss additive and a preparation method thereof. Uniformly mixing 100 parts of lignite, 40-50 parts of organic amine, 10-20 parts of butadiene rubber and 1-2 parts of EDTA, reacting at 220-260 ℃ for 4-5 hours, drying and crushing to obtain a product, namely, tan solid powder. The invention has simple preparation process and good product performance, can maintain the rheological property of the drilling fluid, has good high-temperature salt resistance and water loss reduction property, protects an oil-gas layer from collapse, and reduces the filtration loss of the drilling fluid.
Description
Technical field
The present invention relates to the oil base drilling fluid used in a kind of oil drilling, particularly to a kind of polymer filtrate reducer and
Its preparation method.
Background technology
In oil drilling works, need to add some additives, such as, high-temperature salt-resistant fluid loss additive, to be formed without solid
Phase drilling mud system, reduces dehydration, and formation protection is not polluted by mud, improves drilling speed, reduces drilling cost etc..Organic brown
Coal fluid loss additive is a kind of inorganic agent that oil base drilling fluid is conventional, and this inorganic agent is while reducing filter loss, to full oil base
Drilling fluid has certain viscosity reduction, fall to cut effect.Therefore, less use in the full oil base drilling fluid of low-density, but highly the densest
Spend the control of full oil base drilling fluid rheological characteristic, be suitable to join the full oil base drilling fluid of high density.
Summary of the invention
It is an object of the invention to provide a kind of oil base drilling fluid fluid loss additive and preparation method thereof.
Technical scheme is as follows:
A kind of oil base drilling fluid fluid loss additive, counts, by weight containing following components:
The preparation method of a kind of oil base drilling fluid fluid loss additive, by 100 parts of brown coal, 40-50 part organic amine, 10-20 part
Butadiene rubber and 1-2 part EDTA mix, after reacting 4-5 hour at 220-260 DEG C, and drying and crushing products obtained therefrom, i.e.
Prepare sepia pressed powder.
Described organic amine can be cetylamine, octadecylamine etc..
Beneficial effects of the present invention, preparation technology is simple, good product performance, can keep drilling fluid rheology, high-temperature salt-resistant,
Filtrate-loss control is good, and reservoir protec-tion is anti-collapse, reduces drilling fluid filtration.

Individual hour, drying and crushing products obtained therefrom, i.e. prepare sepia pressed powder.
Embodiment 4
100 parts of brown coal, 40 parts of octadecylamines, 120 parts of maleic rubber and 1 part of EDTA are mixed, reacts at 260 DEG C
5 hours, drying and crushing products obtained therefrom, i.e. prepare sepia pressed powder.
Properties of product are tested
Filtrate loss controllability test is carried out in base is starched.
Base slurry formula is 3% organoclay+5% fluid loss additive+0.5%CaO+10%CaCO3.Compared for product of the present invention with
The product filtrate reducing effects such as FLB-6, SWACO, test result is shown in Table 1:
Table 1 product of the present invention and the filtrate reducing Contrast on effect of other products
Knowable to from upper table, this product A PI filter loss (FLAPI) and high temperature and high pre ssure filtration (FLHTHP) less than FLB-6,
TP-3215, TEC, close to SWACO, filtrate reducing effect is preferable.
