Abstract

The invention relates to a hand-held refrigeration grinding device for oil-containing sandstone. The device can ensure that a rock sample is in a low temperature refrigeration environment when a rock fluorescence slice is prepared through grinding, and crude oil is in a solid state, so that the crude oil in the aperture of the rock sample can be ensured in the initial state. The device is characterized in that: sample holders (2) are heat conductors and are inlaid in one side of a heat transferring core body (3), a heat insulating base (1) is arranged externally at the heat transferring core body (3), the other side of the heat transferring core body (3) closely clings to a refrigeration side of a refrigeration semiconductor (5), and a heating side of the refrigeration semiconductor (5) closely clings to a heat-dissipation top cover (6); and the refrigeration semiconductor (5) can be communicated with an external power supply. The device improves working environment of operators, has the characteristics of low cost and convenient grinding, can be used in hand grinding operations without the need of a huge laboratory.

Description

Technical field: [0001] The invention relates to an original state grinding device for oily rock samples, in particular to a hand-held oily sandstone frozen grinding device. Background technique: [0002] In the field of oil production, crude oil is stored in the pores of underground rocks, and the study of the distribution of remaining oil in the pores of rocks is of great significance to water flooding, polymer flooding and ASP flooding. By studying the distribution state of remaining oil in the pores and the proportion of different distribution states in reservoir rock samples after water flooding, polymer flooding and ASP flooding, targeted development methods can be adopted to enhance recovery. At present, it is generally used to grind oil-bearing rocks into rock fluorescent thin slices, and observe and analyze microscopic remaining oil through fluorescence microscope or laser confocal microscope. However, the crude oil in the rock pores is in a liquid state at room te...
