Rock core cutter and using method thereof

Abstract

The invention discloses a rock core cutter and a using method thereof. The rock core cutter comprises a body and a distribution box, wherein an inner worktable, an outer worktable and a saw frame moving transmission shaft with a saw frame thereon are arranged on the body; a band saw tension regulating valve and a band saw tightness regulating valve are arranged on the top of the saw frame; a driven wheel equipped with a band saw is arranged on the side surface of the saw frame; a control button box is arranged on the front part of the saw frame; a water and liquid nitrogen inlet is formed in the rear part of the saw frame; a V-shaped tool fixing part and a V-shaped tool moving part are respectively arranged on the inner worktable and the outer worktable by virtue of an adjustable V-shaped jaw clamp fixing part and an adjustable V-shaped jaw clamp moving part; and a handle used for the adjustable V-shaped jaw clamp moving part is arranged at the outer end of the outer worktable. The using method comprises the following steps: mounting the band saw, fixing the rock core, cutting the rock core and the like. The rock core cutter and the using method thereof have the advantages that the rock core of different hardness can be subjected to one-time cutting of any ratio, the notch is narrow and small, the energy and materials are saved, and the cutter is applied to water and liquid nitrogen cutting or dry cutting.

Description

technical field [0001] The present invention relates to the field of petroleum exploration and development, more specifically, the present invention relates to a kind of core cutting machine which is used for petroleum exploration and development and can simultaneously cut rock cores of different hardness and the metal materials wrapped around them with one knife and its use method. Background technique [0002] Core is an important physical geological data for studying and understanding underground geology and mineral conditions, and core cutting is a necessary means to obtain first-hand core geological data in oil exploration and development operations. [0003] It is well known to those skilled in the art that in recent years, with the investment in domestic oil and gas reservoir exploration and development projects, various business volumes have been increasing rapidly. Correspondingly, with the continuous increase of core geological data analysis tasks, the demand for l...

AI Technical Summary

Problems solved by technology

[0005] (1) Due to the different materials and hardness of the loose rock core and its external metal sleeves, it is impossible to perform one-time (one-cut) cutting, and only multiple (multi-cut) cutting methods can be used;

[0006] (2) Since the loose rock core wrapped by the metal sleeve is relatively loose, and the method of multiple (multi-knife) cutting is adopted, due to the multiple swings of the blade, it is easy to make the cutting surface uneven, and even the cutter is stuck on the core sample. And thus cause the waste of core samples and cutting tools;

[0007] (3) Since the existing core samples are very valuable, the method of multiple (multi-knife) cutting can easily cause a certain degree of damage to the core samples, which is not conducive to ensuring the authenticity of the internal data of the core samples
