Abstract

The invention relates to the technical field of geological logging, in particular to a screening assembly and device for drilling rock debris. According to the screening assembly for the drilling rockdebris, a sieve inner cavity of a screening unit is partitioned into a plurality of mutually-independent sieve partition cavities by sieve partition plates, and the multiple independent partition cavities can be loaded with different drilling rock debris samples so as to simultaneously screen the different drilling rock debris samples. In addition, a drying mechanism in the screening device is arranged at the end, close to a container opening, of the side wall of a container, a cleaning cavity is close to a water baffle, the screening device is driven by a lifting mechanism to move between the cleaning cavity and the drying mechanism, the drilling rock debris is dried and cleaned, and thus the screening efficiency of the drilling rock debris is improved.

Description

technical field [0001] The invention relates to the technical field of geological logging, in particular to a screening component and a screening device for drilling cuttings. Background technique [0002] In the process of drilling the formation, the underground rock formation is broken by the drill bit and returns to the ground along with the mud, carrying a large amount of drilling cuttings in the mud returned to the ground. Since the drilling cuttings have a certain continuity with the change of the formation, the drilling cuttings can reflect the lithology of different strata. [0003] Currently, drilling cuttings are often used for geological logging. Before using drilling cuttings for geological logging, it is necessary to perform pre-treatment of drilling cuttings, such as screening, cleaning or drying, to improve the accuracy of geological logging. Geological logging requires drilling cuttings samples to be taken every 1-2m. With the increase of drilling depth and...
