Description

Technical Field

[0001] The invention belongs to the technical field of rock cuttings logging, and in particular relates to an automatic scooping and cleaning mechanism for rock cuttings logging. Background Art

[0002] After the underground rocks are broken by the drill bit, they reach the surface along with the drilling fluid. These rock fragments are called rock cuttings, also often called "sand samples". During the drilling process, geologists continuously collect and observe rock cuttings and restore underground geological profiles according to certain sampling intervals and delay times. This process is called rock cuttings logging.

[0003] Prior art CN111396037B discloses a cuttings logging device integrated with a vibrating screen. When the cuttings logging device is in use, when the arrival depth reaches the well section where cuttings logging is required, the first drive device drives the rotating member to rotate, so that a cuttings cup moves to the bottom of the guide plate. At this time, the cuttings cup is in a posture with the open end facing upward. The second drive device opens the cup cover corresponding to the cuttings cup, and the cuttings cup can collect the cuttings of the corresponding well section. The cuttings within the corresponding arrival depth enter the cuttings cup, and the collected cuttings directly enter the corresponding cuttings cup through the vibrating screen. A number of slurry discharge holes are opened on the surface of the cuttings cup to discharge the drilling fluid therein, which will cause part of the drilling fluid to remain on the vibrating screen, which is easy to accumulate for a long time, making it inconvenient to clean and affecting subsequent operations.
