Problems solved by technology

However, the main problem is that the pulverizer and ball mill crush the coarse-grained particles into fine-grained particles when crushing rock samples, which artificially increases the number of fine-grained particles and changes the original particle size distribution pattern of the mud shale. , and also changed the grain shape of some fine-grained particles,

Abstract

The invention provides an apparatus and method for separating shale particles of different particle sizes. The apparatus comprises a vertical beam column equipped with a horizontal hanging rod, wherein the horizontal hanging rod is provided with fixed buckles, a set of a liquid nitrogen bottle and an electromagnetic heater matched with each other, a plurality of polytetrafluoroethylene bottles, software controlling the apparatus, and a base. Crushed sandstone is put into the polytetrafluoroethylene bottles, and the base is allowed to rise, fall and rotate under the control of the software so as to put the polytetrafluoroethylene bottles into the liquid nitrogen bottle and the electromagnetic heater for heating and cooling by turns, so separation of shale particles of different particle sizes is eventually realized. The apparatus and method provided by the invention have the characteristics of rapidness and high efficiency, realize automatic control in the process of separation, and aresimple to operate; the apparatus is low in manufacturing cost; and the apparatus and method are applicable to effective granularity separation of shale formed due to different causes.

Description

technical field [0001] The invention belongs to the field of oil and gas exploration and development, and relates to a separation device for shale particles of different granularity levels. Background technique [0002] Grain size is one of the main characteristics of sediments and sedimentary rocks. It can be used as a quantitative index for the classification of sediments and sedimentary rocks, it can reflect the hydrodynamic properties of sedimentation, and it can also be used as a basis for analyzing and comparing environments. The characteristics of particle size distribution directly affect the physical properties of sediments and sedimentary rocks, such as plasticity, sinterability, porosity and permeability. Therefore, particle size analysis plays an important role in differentiating depositional environments, determining material transport modes, determining hydrodynamic conditions, analyzing particle size trends, stratigraphic division and sublayer comparison.
