Description

Technical Field

[0001] The utility model relates to the technical field of petroleum exploration, in particular to a rock cuttings force separation device for petroleum exploration. Background Art

[0002] Rock cuttings are fragments of parent rock and are mineral aggregates that maintain the structure of the parent rock. The underground rocks are broken by the drill bit and carried to the ground by the circulating medium. They are then washed, air-dried, dried and sieved. Then, petroleum geologists conduct a series of observations and descriptions on them. The sorting and analysis of rock cuttings is an important task in petroleum geological exploration of oil and gas. The sorting, screening and particle size analysis of rock cuttings is one of the important ways to study the origin and sedimentary environment of sediments. Before analyzing the excavated rock cuttings, particle size separation is usually performed to obtain rock cuttings with the same particle size specifications to be tested.

[0003] Publication No. CN219664368U discloses a rock cuttings particle size separation device for oil exploration, which simultaneously performs the separation operation of subsequent batches of rock cuttings during the discharging process, reduces downtime and improves separation efficiency. However, when separating the rock cuttings, the rock cuttings themselves will be attached with impurities such as soil and dust. During the vibration screening, the dust will be shaken off and float into the air. Therefore, during the screening, it will cause the workers to inhale the dust into their lungs, which will affect the health of the workers and pose certain safety hazards. To this end, we propose a rock cuttings force separation device for oil exploration. Utility Model Content
