3.2 Test method
3.2.1 Distilled water test
3.2.1.1 Add 1.00g sodium bicarbonate and 35.00g sodium hydroxide to each sample cup containing 350ml distilled water, and stir at high speed for 20min. The mixture should be interrupted at least twice to scrape off the material adhering to the wall of the cup. 3.2.1.2 Determine the apparent viscosity, filtration loss and pH value of the three suspension samples at 25°C. 3.2.1.3 Calculate the average value of the apparent viscosity, filtration loss and pH value of the three suspension samples. 3.2.24% salt water test
After replacing the distilled water with 4% (m/V) sodium chloride solution, proceed according to steps 3.2.11 to 3.2.1,3. 3.2.3 Saturated salt water test
After replacing distilled water with saturated salt water, proceed according to steps 3.2, 1, 1 to 3.2.1.3. 4 Physical properties test method
4.1 Instruments and reagents
a. Dryer:
b. Balance: sensitivity 0.01g:
c. Drying oven:
d. Standard sieve: aperture 0.076mm;
e. Weighing bottle, 65×35mm:
f. Sodium hexametaphosphate: chemically pure.
4.2 Test method
4.2.1 Determination of water content
4.2.1.1 Weigh 5.00g of sample, place it in a constant weight weighing bottle, dry it at 105±3°C for 2h, cool it to room temperature in a desiccator, and weigh it (accurate to 0.01).
4.2.1.2 Calculation
Water content——
Where: m——mass of sample before drying, g: m——mass of sample after drying, g.
4.2.2 Determination of sieve residue
4.2.2.1 Weigh 10.00g of evaluation soil, add it into 350ml of distilled water containing 0.20g of sodium hexametaphosphate, stir it with a high-speed stirrer for 20min, age it for 2h, and stir it for 20min.
4.2.2.2 Transfer the sample to a 0.076 mm sieve and rinse the soil on the sieve with a water flow of 0.7 kPa from the nozzle for 2 minutes: when rinsing, let the nozzle tip lean against the edge of the sieve and spray the water back and forth on the sieve surface. 4.2.2.3 Transfer the residue from the sieve to a 5-layer evaporating dish, dry it in an oven and weigh it (accurate to 0.01 g). 4.2.2.4 Calculation formula for residue: m sample mass, g mt - residue mass, g.
5 Inspection rules
SY 5444-92
51 This product should be inspected by the quality inspection department of the manufacturer. The manufacturer should ensure that all the residues leaving the factory meet the requirements of the standard. Each batch of products should be accompanied by a quality certificate. 5.2 The unit can test the quality of the received evaluation soil according to the rules and test methods specified in this standard to check whether its indicators meet the requirements of this standard.
5,3 Sampling method: Use a sampler to take samples from at least 5 packages of each batch of products, and the small batch shall not be less than 5 bags. When sampling, insert the sampler along the vertical center line of each bag, and sample no less than 50g per bag. Mix the sample thoroughly and divide it into two parts and put it in clean, dry, wide-mouth bottles with ground stoppers. A label is attached to the bottle to indicate: manufacturer name, product name, batch number, sampling date and location. One bottle is sent to the laboratory for inspection, and the other bottle is kept for three months for arbitration. 6 Packaging and marking
6.1 Packaging
6,11 The packaging bag should have sufficient strength and at least two layers to meet the requirements of moisture-proof and non-damage. 6.1.2 The inner and outer seals of the package should be tied separately. 6.1.3 The net weight of each bag is 1k or 5k%, and the allowable error is 2%. Randomly select 50 bags from each batch of products, which should be within the allowable error range.
6.2 Marking
6.2.1 The outer layer of the packaging bag should be printed with the words "Pingguantu" in bold and prominent font on the top, and the manufacturer's name should be printed below. Additional remarks:
This standard is proposed and managed by the Drilling Professional Standardization Committee. This standard was drafted by the Drilling Institute of Petroleum Exploration and Development Research Institute of China National Petroleum Corporation. The main drafters of this standard are Li Jiajun and Wu Peiyi. This standard continues to be effective after the review in 199, and the review result has been approved by the State Administration of Petroleum and Chemical Industry.
