Precautions for daily maintenance of drilling fluid
① Carefully observe the performance and level changes of drilling fluid to ensure well control and downhole safety.
② Master the rules of pretreatment and learn to use water to maintain drilling fluid (water-based drilling fluid) to regularly inspect and maintain the solid control system and solid control equipment.
③ Perform indoor small tests and chemical treatment of drilling fluid.
a. Perform small tests before treatment.
b. Formulate a good treatment plan and choose a suitable treatment time.
c. The amount of treatment agent added should not exceed 50% to 80% of the amount added in the small test, and should be added evenly within one cycle.
d. During the treatment process, observe, measure, test and treat at the same time.
e. After treatment, measure the cycle.
④ Timely and correctly measure the performance of drilling fluid.
⑤ Record and organize information and data.
⑥ Regularly calibrate drilling fluid instruments to ensure accuracy.
The maintenance of drilling fluid performance is very important to ensure drilling efficiency and drilling safety, so regular observation and adjustment at any time are very necessary. When measuring, it is necessary to ensure the accuracy of the data.
