The role of petroleum drilling grade montmorillonite:
1. High slurry making efficiency and cost savings: After purification and activation, the effective montmorillonite component is high, and the addition amount is less at the same viscosity. A small amount of powder can be used to prepare qualified drilling fluid, reducing the overall material cost; Ordinary raw ore soil contains many inert impurities and requires a large amount of feeding to increase the solid content of the mud.
2. Forming a dense mud cake to reduce filtration and prevent well collapse: After sufficient hydration, a thin and tough mud cake is formed on the wellbore to seal small pores in the formation, reduce drilling fluid infiltration into the formation, and protect the reservoir; At the same time, it suppresses the water absorption, loosening and peeling of rock layers, and alleviates the problems of collapse and block falling in water sensitive strata.
3. Excellent thixotropy and strong sand carrying capacity in suspension: the viscosity of the drilling fluid is moderate when circulating, making pumping effortless; After the drilling stops and comes to a standstill, the viscosity increases, stabilizing the suspended drilling slag and weighting materials, avoiding sand settling and drilling jamming caused by drilling cuttings, and reducing the risk of underground accidents.
4. Low sand content, protecting drilling equipment: strict control of hard and inert impurities such as quartz, less likely to block pipelines and vibrating screens, reducing wear and tear on mud pumps and drilling tools, reducing downtime and maintenance frequency, and extending equipment service life.
5.Durable and stable mud performance: With sufficient hydration and strong colloidal stability, drilling fluid is not easily stratified and its performance is not easily degraded rapidly. Even after long-term drilling, viscosity and filtration indicators can still be maintained, reducing frequent on-site mud mixing.
Details and craftsmanship
1. It has excellent cation exchange performance, can adsorb middle and formation salt water, calcium and magnesium ions, harmful impurities, resist mud pollution, prevent drilling fluid viscosity collapse and system failure, and ensure the stability of complex water quality formation mud.
2. During the mud circulation process, the drill bit is continuously cooled and flushed, quickly removing high temperatures and frictional heat from drilling, reducing drill bit erosion and wear, significantly extending the service life of the drill bit, and improving pure drilling efficiency.
3. Effectively inhibit the water absorption, swelling, and stripping of loose mudstone and shale to prevent formation shrinkage and hole expansion, reduce complex underground situations, and maintain regular and unobstructed wellbore.
4. Forming mud cakes can form a protective film on the surface of metal drilling tools and wellbore walls, isolating air and corrosive media in the formation, reducing drilling tool corrosion and wellbore corrosion.
5.The high-purity activated structure is resistant to high temperature and high pressure, and the colloid remains intact and its performance does not deteriorate under high temperature conditions in deep and ultra deep wells. It will not cause mud thinning or instability problems.
Material, Safety, and Cat Experience
1.Controllable selection of raw materials:High grade sodium based bentonite raw ore is selected and processed through beneficiation and purification, wet sodiation activation, and multi-stage sand removal technology. Inert impurities, heavy metals, and soluble harmful salts are strictly controlled, resulting in high batch stability and minimal fluctuations in indicators.
2. Easy disposal of waste:Montmorillonite in drilling waste mud can naturally settle, and after solid-liquid separation, the solid phase is easy to store and handle; It will not produce recalcitrant organic pollutants and meet the environmental control requirements of most construction sites.
3. Mature supporting usage plan:Based on practical experience, we can provide dosage suggestions, soda ash activation ratios, and compounding solutions with filtration reducers and inhibitors to quickly help customers solve on-site problems such as insufficient viscosity, excessive filtration, sand settling, and diameter reduction.
User Guide
1. Check the mixing equipment to ensure that the mixing impeller has sufficient shear force to prevent powder agglomeration, ball formation, and the occurrence of "fish eyes" that are difficult to hydrate.
2. After the feeding is completed, it should be thoroughly stirred at high speed, and the conventional stirring hydration time should not be less than 30-60 minutes; Prolong the hydration time appropriately in low-temperature environments.
3. It is strictly prohibited to mix with high concentration electrolyte agents at once, as it will inhibit the hydration of montmorillonite and cause viscosity to not increase.
4. If there is poor hydration and low viscosity, extend the mixing time, add a small amount of soda ash, and do not blindly add a large amount of powder.
5. The warehouse is stored in a rainproof, moisture-proof, and ventilated manner, with bottom pallets to isolate moisture from the ground.
FAQs
Q: Why doesn't the viscosity of the mud increase even after adding montmorillonite?
A: The most common reason is not product quality issues, but inadequate hydration: the water quality is too hard, the salt and calcium content are high, the one-time feeding is too fast and clumps up, the mixing and shearing are insufficient, and the hydration time is too short. Solution: Slow down the feeding, extend the stirring for 30-60 minutes, and adjust the water quality with an appropriate amount of soda ash to quickly increase the viscosity.
Q: Will drilling montmorillonite block the screening and pump?
A: Regular drilling grade has undergone sand removal and purification, with extremely low sand content and no equipment blockage. Low cost quartz and gravel with high impurities on the market are the reasons for problems such as screen blockage, pump grinding, and tank piercing. High purity drilling grade can significantly reduce equipment wear and solid control load.
Q: What are the reasons for the poor mixing effect in cold weather and winter?
A: The hydration rate slows down at low temperatures, and the colloid does not fully stretch. In winter, simply extending the hydration mixing time and adding a small amount of soda ash for activation can restore normal viscosity and suspension performance.
Q: How to solve the problem of mud static stratification and severe sand settling?
A: Insufficient thixotropy and colloid strength. Most likely, it is due to a lower grade or incomplete hydration. After replacing high-purity drilling grade montmorillonite and fully pre hydration, the static thickening effect is strong, which can firmly suspend drilling cuttings and prevent sand settling and drilling jamming.
Q: Can the product still be used if it gets damp?
A: Slight moisture does not cause failure, and after being crushed and dispersed, it can be used normally; Severe agglomeration and long-term exposure to rain can reduce the slurry production rate. It is recommended to reduce the single feeding amount and extend the mixing time to compensate for performance.
Q: Will it corrode the equipment and be environmentally unfriendly?
A: Pure natural inorganic minerals, no chemical corrosion, no volatilization, and not classified as hazardous chemicals. Drilling waste slurry is easy to settle and handle, which is safe for the formation, equipment, and construction personnel, and meets the requirements of on-site environmental protection construction.
