GSP is a kind of advanced mixed hydrocarbon, plant extracts and polymer crosslinking graft reaction by special wake processing new multifunctional precipitation agent preparation. Using the scientific formula and synthetic products, advanced production technology, so as to realize high quality and inexpensive, is to ensure that one of the best selection of high quality drilling.
Two, physical and chemical properties
Appearance: dark grey powder
Fineness: 20 standard sieve margin is less than or equal to 5%
The moisture is less than or equal to 10%, three mud performance
| project | index |
| Base mud | The slurry after +2%GSP treatment |
| API water ml/30min | 14 - 16 | Less than or equal to 10 |
| The apparent viscosity of mpa.s | Twelve | Less than or equal to 20 |
| HTHP filtration ml/30min | 50 - 54 | Less than or equal to 28 |
| Relative expansion% reduction |
| More than 50 |
| PH value | 9 - 10 | 9 - 10 |
Four, the characteristics of performance
1, in moderate viscous conditions, significantly reduce water loss;
2, with polymer coated and embedded ions inhibit the sidewall expansion size function;
3, has good adsorption filling shaft strengthening function;
4, can form a layer of hydrophobic oil film on the pipe wall, reduce the torque to prevent sticking;
5, strong anti pollution ability, can be used for salt layer drilling, anti temperature up to 150 DEG c;
6, has a selective flocculation effect, to clear debris.
Five, application
GSP powder added directly (preferably with a mixed leakage leakage of mud mix);
1 large diameter drilling recommended dosage: General strata 1-2%, 2-3% complex formation;
2 small diameter drilling recommended dosage: rope core 0.5-1%, water sensitive formation 1-2%.
Six, packaging storage
This product adopts three in one bag lined with polyethylene film bag, net weight of each bag is 25kg; stored in a cool, dry,
Packing: in plastic woven bags lined with double thin film packaging, 25 kg / bag.
Ventilation department. Avoid contact with eyes, skin and clothes or contact with plenty of water to wash away from fire.
