Abstract
The invention introduces a downhole failure analysis and processing method and device based on the partical diameter distribution of drilling cuttings. The device includes body frame, screening component, feeding system, weighing mechanism, driving mechanism and control system, which can realize automatic grading and screening according to the partical diameter of cuttings and weigh the cuttings at all levels; the method adopts the debris sieving device to measure the particle diameter distribution of cuttings, establishes a standard partical diameter distribution database of cuttings, compares with the real-time partical diameter distribution of cuttings to detect the downhole failure, and then selects the corresponding failure solution from the downhole failure data to remove the downhole failure. The invention can sieve cuttings according to the partical diameter grading, obtain the partical diameter distribution of cuttings, quickly identify the downhole failure according to the partical diameter distribution of cuttings, and remove the downhole failure.
