4.2 Drilling fluid performance test method
4.2.1 Base slurry formula: add 60.0g of drilling fluid test sodium to 100ml distilled water. 4.2.2 Heat the distilled water to 75℃. Prepare the slurry according to SY5060, and make the base slurry performance meet the requirements of Table 2 in this standard. 4.2.3 Add 7. 0g SMK (dry) was prepared into test slurry. At the same time, it was stirred with a scoop for 5 minutes and then with a high-speed stirrer for 20 minutes. During this period, the slurry was interrupted at least twice to scrape off the test slurry adhering to the wall of the cup. 4.2.4 Under the condition of 24+3\℃, the viscosity of Φn (100r/tnin), apparent viscosity, dynamic shear force, and static shear force of 1min were measured. 4.2.5 The test slurry was put into the curing tank, put into the roller furnace, and rolled at 180℃ for curing for 16 hours. After cooling, it was taken out and stirred at high speed for 5 min, determine the test slurry properties according to 4.2.4.

4.3.3 Determination of water-insoluble matter
4.3.3.1 Dissolve the sample after water content inspection in distilled water (add hot distilled water or heat on a water bath to help dissolution), transfer the solution into a 500ml volumetric flask, and dilute to the scale. Filter in two funnels with ten filter papers. Take 25.00mL from each of the two collected filtrates, put them into two known mass flasks, evaporate to 1 on a water bath. Then put it in a drying oven at 105±3℃ and dry to constant weight. 4.3.3.2 Calculation:
