With the mass fraction of sulfonated-pheno-formoldehyde resin gross mass.
1, the influence of different modifying agent and dosage to product intrinsic viscosity
Fig. 1 is the influence of dressing agent and dressing agent dosage to modified outcome intrinsic viscosity.It will be seen from figure 1 that using not
Same dressing agent influences difference to product intrinsic viscosity, and for dressing agent 1, with the increase of dressing agent dosage, gained modification is produced
The intrinsic viscosity of object gradually decreases, and when one timing of dressing agent dosage, reduction eases up, and when use dressing agent 2, the spy of modified outcome
Property viscosity number first improved with the increase of dressing agent dosage after again reduce.It is said in terms of ultra-high temperature drilling liquid is to the requirement of inorganic agent,
It is relatively good that salt resistance high temperature and pressure fluid loss additive is synthesized with dressing agent 1.
2, influence of the dressing agent to product property of drilling fluid
The basic recipe of drilling fluid used in the survey are as follows: 4% sodium bentonite slurry+1.0%LP527+1.5%MP488+
6%SMC+7% modified outcome+0.5%XJ+0.75%NaOH+10%NaCl is weighed out to density 2.3g/cm with barite3.It will
Then prepared drilling fluid is cooled to 55 DEG C and surveys its rheological characteristic in 220 DEG C of aging 16h, while measuring high temperature and high pressure filter loss
(180 DEG C, pressure difference 3.5MPa, similarly hereinafter) investigate the performance of product by high temperature and high pressure filter loss.
(1) influence of different modifying agent and dosage to property of drilling fluid handled by product
Fig. 2 is influence of the dressing agent dosage to drilling fluid apparent viscosity, plastic viscosity and yield value.It can from figure
Out, with the increase of dressing agent dosage, apparent viscosity, the plastic viscosity of drilling fluid handled by product are gradually decreased, for repairing
The product that agent 2 synthesizes is adornd, after dressing agent dosage is more than 28%, apparent viscosity and plastic viscosity increase again.And use gained
The yield value of drilling fluid handled by product is gradually decreased with the increase of dressing agent dosage, illustrates the production by modification from this point
Object can control drilling fluids at high temperature thickening phenomenon.
Fig. 3 be dressing agent dosage at the beginning of drilling fluid handled by product, the influence of egress.It can be seen from the figure that for repairing
Agent 1 is adornd, with the increase of dressing agent dosage, products therefrom ingressing for drilling fluid of processing is first reduced, and rear to increase again, egress first increases
Add, then reduces, it is rear to increase again.For dressing agent 2, with the increase of dressing agent dosage, products therefrom processing drilling fluid is ingressed
It gradually decreases, egress first increases, rear to reduce again.But total trend is with the increase of dressing agent dosage, the first of drilling fluid, egress
It reduces.
Fig. 4 is influence of the dressing agent dosage to drilling fluid API filtration and high temperature and high pressure filter loss.It can from figure
Out, dressing agent 1 is gradually decreased with the increase of dressing agent dosage with the filter loss of products therefrom processing drilling fluid, for
Dressing agent 2, with the increase of dressing agent dosage, the filter loss of drilling fluid first increases to be reduced afterwards.And the high temperature and pressure filter of drilling fluid
Vector is greatly lowered with the increase of dressing agent dosage, rises after dressing agent dosage is more than 23%, and slightly, in experiment item
17%~28% pair of control high temperature and high pressure filter loss of dressing agent dosage is more advantageous under part.
Apparent viscosity, plastic viscosity, yield value and first, egress and the high temperature for comprehensively considering drilling fluid handled by product are high
Filter pressing loss, dressing agent dosage is preferable in 23%~28% effect under experimental conditions, and uses 1 products therefrom performance of dressing agent
Better than dressing agent 2.
(2) influence of the salt dosage to property of drilling fluid handled by modified outcome
On the basis of condition experiment, dressing agent 1 is selected to carry out Product formation (embodiment 1), and investigates salt dosage to repairing
Adorn influence (the base slurry composition used: 4% sodium bentonite slurry+1.0%LP527+1.5%MP488+6% of product property of drilling fluid
SMC+7% modified outcome+0.5%XJ+0.75%NaOH is weighed out to density 2.3g/cm with barite3), table 1 is salt dosage pair
The influence of modified outcome rheological characteristic, Fig. 5 are (220 DEG C/16h of influence of the salt dosage to drilling fluid filtration handled by modified outcome
It measures afterwards).
Influence of the 1 salt dosage of table to modified outcome drilling fluid rheology
Note: it is 1. measured at 55 DEG C；2. too thick can not measure.
As it can be seen from table 1 the salt-resistance of product can significantly be improved by introducing dressing agent in synthesis.From drilling fluid
Rheological characteristic sees that drilling fluid anti-salt property handled by the product (i.e. SMP) without dressing agent is poor, and high temperature thickening occurs, and draws
Enter obviously eliminate after dressing agent high temperature thickening phenomenon, and with the increase of dressing agent dosage, the viscosity of locating drilling fluid by
It gradually reduces, rheological characteristic is further improved.From the point of view of high temperature and high pressure filter loss, with the increase of dressing agent dosage, salt resistance energy
Power improves, and filter loss reduces, but after dressing agent dosage reaches a certain amount of, is further added by dressing agent dosage to filtrate reducing influential effect
Less.Under experimental conditions, it is contemplated that the production cost of product, dressing agent dosage both can be with guarantee systems 23%~28%
Rheological characteristic can guarantee that high temperature and high pressure filter loss is lower again.
3, influence of the addition of filtrate reducer to property of drilling fluid
Table 2 is the dosage of sample 1 and sample 2 synthesized by embodiment optimization of C/C composites to drilling fluid rheology handled by product
With the influence of filter loss.Its drilling fluid composition: 4% sodium bentonite slurry+1.0%LP527+1.5%MP488+6%SMC+0.5%
The NaCl+0.25% surfactant of XJ+3.0gNaOH+20% aggravates consistency 2.3g/cm with barite3, filter loss exists
It is measured after 220 DEG C/16h aging.
Influence of the 2 modified outcome dosage of table to drilling fluid rheology handled by product
Note: it is 1. measured at 55 DEG C；2. too thick can not measure.
It can be seen that the increase with fluid loss additive sample dosage from Fig. 5 and table 2, filter loss is substantially reduced, when dosage is
The high temperature and high pressure filter loss of system can be controlled within 15ml when 7%, and drilling fluid rheology is further after high temperature
Improved, illustrates that the thinking of synthesizing high temperature high pressure fluid loss additive of the present invention is feasible.
