SY/T 5092—2002
This standard is a revision of SY/T5092—93 "Sulfonated lignite for drilling fluid". The main technical difference between the revised standard and SY/T5092—93 is the change in the determination method of dry basis humic acid content (from spectrophotometry to gravimetric analysis), which improves the accuracy of the determination. In addition, the revised standard makes some adjustments to the technical requirements, reducing the drilling fluid performance requirements from 5 to 4, and the physical and chemical properties set a limit for the chromium ion content.
This standard will replace SY/T5092-93 from the date of implementation. The appendix A and appendix of this standard are normative appendices. This standard is proposed and submitted by the Petroleum Drilling Engineering Professional Standardization Committee. The responsible drafting unit of this standard is: Drilling and Production Technology Research Institute of Sichuan Petroleum Administration Bureau. The participating drafting unit of this standard is: Chengdu Chuanfeng Chemical Engineering Co., Ltd. The main drafters of this standard are: Shi Engang, Lan Xia, Tu Zhenquan, Zhou Xiancheng, Huang Li, Liu Dengbi, Huang Ling. The previous versions of the standards replaced by this standard are: -SY 5092-87, SY/T 5092-93.

SY/T 5092—20025 The dry humic acid content Y expressed as a mass fraction is calculated as follows: V (mi-m2)
SY/F S092-2002
Wherein:
Y is the dry humic acid content, expressed as a percentage; ml is the mass of humic acid, in grams (g); m2 is the mass of the ignition residue of humic acid, in grams (g); V is the total volume of the sample solution, in milliliters (mlL); V is the volume of the sample solution taken during the determination, in milliliters (mL); m is the mass of the sample, in grams (g). 4.4.4 Determination of dry total chromium
4.4.4.1 Weigh 0.50g0.02g (accurate to 0.0001g) of the sample into the porcelain. Gently vibrate the crucible to flatten the sample, put the crucible with the sample into the furnace, heat it to 800℃, keep the temperature constant for 30min, cool it for 300min, take it out: clamp the crucible into a 250mL beaker, add 25mL sulfuric acid solution (2mol/L) to the glass, use a glass rod to pick up the crucible, wash it and take it out, add 251ml ammonium persulfate solution (200g/L) and 10mL silver nitrate solution (25g/L), add distilled water to dilute to 150ml, heat it to boiling 10ml on the furnace, take it out and cool it to room temperature, add 10mL phosphoric acid and mix it. When the ammonium ferrous sulfate standard solution (0.103tmol/l) is titrated to light yellow, add 4 drops of sodium diphenylamine sulfonate indicator and continue to drip until the purple-red turns green as the end point. 4.4.4.2 The total chromium content Z expressed by mass fraction is calculated as follows: z-51996 × cy×100%
Wherein:
-dry basis total chromium content, expressed as a percentage; c--ferrous sulfate standard solution concentration, in moles per liter (mol/l.); V.-consumed ammonium ferrous sulfate standard push solution volume, in milliliters (mL): m--base sample mass, in grams (g): 51.996--1mcl chromium ion mass, in grams per mole (g/ml) 4.5 Precision
When the absolute error of each parallel determination value is within the tolerance range specified below, take its arithmetic mean. 4.5.1 Physical and chemical properties parallel determination tolerance value
a) Water content: 1.0%;
b) Base total chromium: 0.2%;
c) Dry basis humic acid: 3.0%.
4.5,2 Test slurry properties parallel determination tolerance value before high temperature curing/after high temperature curing] a) 100t/mn reading: 1.0/1.0;
b) Apparent viscosity: 05mPas/1mPa*s
