Product Description
Oil additives A, characteristics Drilling with theunidirectional pressure agent DF - 1, was approved by the special craft processing variety of natural fibers and filling particles and additives, click on the appropriate gradation and certain technology compound and into the tawny powder product. Products in drilling add after one-way pressure difference under the action of stratum, can have various leakage a good sealing effect, use convenient, compatibility sex good, do not affect the mud property. Second, main performance indexes Project indicators appearance Yellowish or yellow powder Density, g/cm3 1.60 - daughters Sieve allowance (aperture 0.28 mm standard screen), % acuities 10.0 Moisture, % acuities 8.0 Burning residua, % acuities 7.0 Water soluble content more than 5% Closed filter vector, ml acuities 35.0 PH 7-8 Density variation, g/cm3 acuities 0.02 Note: burning residua item used in plant fiber class 36-45% Physiochemical index Table 2 drilling fluid performance indicators Three, use Drilling with theunidirectional pressure agent DF - 1, suitable for drilling in situations of porous and micro cracks formation leakage filter lost. This product is good compatibility sex are applicable to different system, different density of drilling and completion fluid leakage, to achieve the effective tiny cracks the sealing, and can improve the quality of mud cake, reduce water loss. The products recommended added amount of 4%. Physical and chemical properties: appearance: hoar powder fineness: 40 eye watering: more than 14% PH: 7-9. Mud properties: Item mesh base pulp Base pulp 4% 801 Dense degrees, g / 3 cm 1.03 More than 1.03 Apparent viscosity, mPa. S 7-10 Acuities 11 Plastic viscosity, mPa. S 6-9 More than 10 API dehydrate, ml 15-17 More than 10 Closed filtration, ml / 30min All lost More than 50 Special levy: 1 to pore and micro cracked loss, plugging speed, the effect is good. 2 can rapidly forming a certain intensity of the permeability shielding with the liquid, prevent working liquid and solid phase invading reservoir, reservoir from damage, shielding against row with through the perforating shall release. 3 could significantly reduce the mud filtration, and it doesn't affect the rheology of slurry can, anti-scar excellent performance. 4 does not suffer electrolyte pollution affects, avirulent, harmless. Method of use: 1 to prevent leakage dosage 1-2%. 2 fibrobronchoscopy sand layer porosity and micro fractures, protecting reservoir, dosage is 2-4%. 3 fibrobronchoscopy serious thief zone, dosage is 4-6%. packaging The product adopts outer textile bags, inner bags of three-in-one each bag bag, quality, allowing the 25kg error 1% The product should be kept in a cool and dry place, prevent sun, prevent packing damage and moistureproof.
