Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of rock debris logging, and particularly relates to a rock debris logging automatic fishing and cleaning mechanism. BACKGROUND

[0002] After the underground rock is broken by a drill bit, the rock fragments reach the ground along with drilling fluid, and these rock fragments are called rock debris, also commonly known as "sand sample". In the drilling process, geologists continuously collect and observe rock debris and restore the underground geological profile according to a certain sampling interval and delay time, which is called rock debris logging.

[0003] The prior art CN111396037B discloses a rock debris logging equipment integrated with a vibrating screen. When the delay depth reaches the well section where rock debris logging is needed, the first driving device drives the rotating member to rotate, so that one rock debris cup moves to the lower side of the guide plate. At this time, the rock debris cup is in an open end upward posture. The second driving device opens the cup cover corresponding to the rock debris cup. The rock debris cup can collect the rock debris of the corresponding well section. The rock debris in the corresponding delay depth enters the rock debris cup, and the collected rock debris directly enters the corresponding rock debris cup through the vibrating screen. A plurality of rows of slurry holes are formed on the surface of the rock debris cup to discharge the drilling fluid therein, which will cause part of the drilling fluid to remain on the vibrating screen. Long time accumulation is not convenient for cleaning and affects subsequent operations. SUMMARY
