Abstract
The invention discloses a drilling fluid plugging performance evaluation method which comprises the following steps: step 1), utilizing a low-temperature low-pressure filter press to measure the API filter loss of drilling fluid to be measured and taking filter cake; step 2) injecting clean water into a drilling fluid cup of the low-temperature low-pressure filter press, covering the drilling fluid cup by the filter cake obtained in step 1); step 3) under the experimental condition the same as the API filter loss of the drilling fluid to be measured, measuring initial permeable time and permeable amount of the filter cake in step 2) and evaluating the strength of the plugging performance of the drilling fluid according to the size of the permeable amount of the filter cake and the initialpermeable time. The evaluation method disclosed by the invention has the advantages that an experiment process is simple, the operability is strong, an experimental period is short, the experimental conditions are closer to the real downhole conditions, and the experimental data and the experimental results have stronger guidance for on-site drilling production; thus, the evaluation method is veryworth of popularization and application.
