4.3.5.1 Method Summary
The turbidity salinity of SMP aqueous solution is measured by incident light with a wavelength of 362mml. The same concentration of SMP aqueous solution is added to salt water of different concentrations: when the salinity of the solution (in CI) is lower than the turbidity salinity of the product, the extinction value E (hereinafter referred to as E value) of the solution has nothing to do with the salinity of the solution (the H value of the solution should be roughly the same). When the salinity in the bay liquid reaches or exceeds the turbidity salinity, the solution becomes turbid and the E value increases significantly. The greater the salinity of the solution, the greater the E value. The significant change in the value can be used to determine that the solution is turbid, thereby measuring the turbidity salinity of the product. 4.3.5.2 Determination steps
a: Weigh 34.4g of sodium chloride burned to constant weight at 500-600℃, weigh to 0.01g and dissolve in 100mL of distilled water to prepare a sodium chloride paint solution with a chloride concentration of 180L. Use the solution prepared in a to calculate and dilute according to formula (4) to obtain sodium chloride solutions with chloride ion concentrations in Table 2: CV=cV

c. Prepare SMP solution with a concentration of 50g/L: Weigh 5.0g of sample (based on T) and place it in a 100mL beaker, add 80ml of distilled water: heat to dissolve it, then make up to volume with a 1001nL volumetric flask, filter, and set aside the remaining filtrate. Take 9 test tubes with cold scale, and add 1.00 μL of sample solution (filtrate) and 9.00 mL of sodium chloride solution 1 to 9 in Table 2 to each test tube respectively: shake carefully to mix well. The SMP concentration and chloride ion content in each test tube are shown in Table 3. e. Use a spectrophotometer (incident light wavelength 362 nm, colorimetric thickness 0.5 cm) to measure the extinction value E of each solution. 4.3.5.3 Result evaluation
When the extinction value E of the solution does not reach the turbidity point salinity, the difference between the E values ​​of each number is within 0.02. From the base number, the difference between the E value and the previous F value is equal to or greater than 0.02, and this number appears turbid, then the chloride ion concentration of the solution of this number is the turbidity point salinity of the sample. 4.3.6 High temperature and high pressure filtration loss
4.3.6.1 Method summary
SY/ T 509495
This method is to use a 42-type or similar high temperature and high pressure filtration meter to measure the filtration loss of the product test slurry at 150℃ and a pressure difference of 3.5MPa.

Stir the base slurry at high speed for 5 minutes, and test the base slurry filtration loss according to 4.3.2.1 of SY/T5621. The filtration loss should be within the range of 65 + 10mL. The filtration loss of the rock base slurry is not within this range. The amount of the two soil powders can be appropriately adjusted to make the base slurry meet the requirements. The base slurry is ready for use.
