Description
Technical field
The present invention relates to field use auxiliary material fields, more particularly to a kind of viscosity depressant for drilling fluid and its producer
Method.
Background technique
Mud shale stratum hole instability becomes the technical problem frequently encountered in drilling engineering, especially in depth
Well, ultradeep well, directional well and high angle hole it is increasing in the case where, water sensitive active mud shale, soft mudstone easily aquation are swollen
It is swollen, especially drilling easily collapse mud shale layer, the deep stratum Yi Ta, salt cream mud bad ground etc. easily occurs peeling, chip off-falling it is existing
As causing blocked portion, suppressing pump phenomenon, bring biggish risk to construction and later period well completion work, the above problem seems more prominent
Out, in the work progress of drilling well, people are frequently added anti-sloughing agent and fluid loss additive to solve the above problems, and routine is anti-collapse
Agent, it is difficult to really effective closure is realized, and compatibility is poor, while the prior art, because lacking effective thinner, rheological characteristic
Difference limits its use scope.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of viscosity depressant for drilling fluid and its producers

Preferably, a kind of production method of viscosity depressant for drilling fluid, comprising the following steps:
A, production scene is cleared up, determines product formula, checks whether mechanical equipment can run well, prepares former material according to the ratio
Material；
B, reaction kettle agitating paddle is opened, vacuum pump is started, vacuum-pumping valve is opened, passes through discharging valve of reaction kettle goalkeeper's raw material
Dioxy
SiClx 66%-73% is drawn into kettle, is then added raw material potassium hydroxide 27%-36% with same method, is added
Material terminates laggard
Row reaction, the reaction time 5 hours；
C, after reaction, the finished product in reaction kettle is put into 200 liters of plastic barrels by blowing pipeline；
D, fixed weight: 200 kilograms/barrel, sealing packaging, finished product is neatly packed, and mark is clear；

There is good viscosity reducing effect；The present invention is good in the drilling fluids such as polymer, organosilicon, formates using effect.
Specific embodiment
It elaborates below to the embodiment of the present invention, the present embodiment carries out under the premise of the technical scheme of the present invention
Implement, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to following implementation
Example.
A kind of viscosity depressant for drilling fluid provided in this embodiment, based on metering accounting number: including silica 66%-
73%, potassium hydroxide 27%-36%.
Preferably, a kind of viscosity depressant for drilling fluid, based on metering accounting number: including silica 67%, potassium hydroxide
30%.
Preferably, a kind of viscosity depressant for drilling fluid, based on metering accounting number: including silica 70%, potassium hydroxide
32%.
Preferably, a kind of viscosity depressant for drilling fluid, based on metering accounting number: including silica 70%, potassium hydroxide
30%.
Preferably, a kind of production method of viscosity depressant for drilling fluid is synthetically produced in line equipment in liquid and carries out, including with
Lower step:
A, production scene is cleared up, determines product formula, checks whether mechanical equipment can run well, prepares former material according to the ratio
Material；
B, reaction kettle agitating paddle is opened, vacuum pump is started, vacuum-pumping valve is opened, passes through discharging valve of reaction kettle goalkeeper's raw material
Silica 66%-73% is drawn into kettle, then adds raw material potassium hydroxide 27%-36%, charging knot with same method
It is reacted after beam, the reaction time 5 hours；
C, after reaction, the finished product in reaction kettle is put by blowing pipeline (will notice in 200 liters of plastic barrels
Room inspection by sampling is tested, can be packed after the assay was approved through laboratory)；
D, fixed weight: 200 kilograms/barrel (error ± 0.5 kilogram), sealing packaging, finished product is neatly packed, and mark is clear；
E, warehousing finished products.
Current embodiment require that explanation, the application method of the invention can be added directly into circulating fluid or preparation
It is added in circulating fluid at glue, dosage 0.5-1.0%；It is packed and storing, the present embodiment invention using plastic barrel or
Metal bucket packaging: it 100kg/ barrels, 200kg/ barrels, can also be packed by user's requirement.The physical and chemical index of the present embodiment invention:
| Project | Index |
| Appearance | The viscous liquid of free-flowing |
| Viscosity break ratio, % | ≥80.0 |
It should be noted that viscosity depressant for drilling fluid organosilicon BJN-1 is the most newly synthesized novel thinner of one kind.
Silicate drilling fluid, semi-permeable membrane drilling fluid have the novel water-based drilling fluid of high film effectiveness, their membrane efficiency exists
Between 55%~85%, the effect similar to oil base drilling fluid is played in terms of shale formation stabilization, prevents water and drilling fluid
Into stratum, it is effectively prevented stratum hydration swelling, stratum stratification crack is blocked, prevents the migration of clay particle in stratum, is prevented
Oil-gas Layer is protected in only cave-in；Although silicate drilling fluid, anti sloughing effectiveness are good, because lacking effective thinner, rheology
Property is poor, limits its use scope；Thinner BJN-1 all has good drop in silicate drilling fluid, semi-permeable membrane drilling fluid
Viscous effect.
The present invention has the advantage that the present invention has in silicate drilling fluid, semi-permeable membrane drilling fluid compared with prior art
There is good viscosity reducing effect；The present invention is good in the drilling fluids such as polymer, organosilicon, formates using effect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
