Full-automatic rock core sampling device

Abstract

The invention discloses a full-automatic rock core sampling device. The full-automatic rock core sampling device comprises a fixed bracket, a plurality of stand columns and a support bracket, wherein the plurality of stand columns are arranged on the fixed bracket; the support bracket is positioned above the fixed bracket; the left side of the support bracket is supported on the plurality of stand columns; a thrusting hydraulic cylinder I is mounted on the right side of the fixed bracket and used for supporting the right end of the support bracket; a cylinder body of the thrusting hydraulic cylinder I is fixed on the fixed bracket; the top end of a piston rod of the thrusting hydraulic cylinder I is supported on the right side of the support bracket; a sliding plate capable of moving forward and backward is arranged on the support bracket; a mounting base for mounting a rock core sampling driller is mounted on the front of the sliding plate; a sliding rail, on which the sliding plate slides forward and backward, is fixed on the support bracket; a counter-force pushing plate is fixed on the left side of the support bracket; the rock core sampling driller and the sliding rail are arranged in parallel; the rock core sampling driller is arranged above the sliding rail; and a thrusting hydraulic cylinder II is mounted between the sliding plate and the counter-force pushing plate. The full-automatic rock core sampling device is simple in structure, reasonable in design, low in investment cost, simple and convenient to use and operate, good in using effect and capable of automatically finishing a rock core sampling process.

Description

technical field [0001] The invention relates to a sampling device, in particular to a fully automatic rock core sampling device. Background technique [0002] The core is a roughly cylindrical subterranean material test piece taken out from the ground for testing with a special drilling machine (such as a core sampling drilling machine). Rock core is an important physical material for studying and understanding underground geology and mineral conditions. For example, in the process of oil and gas field exploration and development, according to the stratum level and design depth obtained by investigation, the rock sample drilled by the coring tool into the well is the core. The core is the most intuitive and practical data to understand the characteristics of the underground oil layer and the fluid contained in it. There are mainly two sampling methods: sidewall coring and drilling coring. But nowadays, manual sampling is generally used when actually sampling rock cores, wh...

Problems solved by technology

But nowadays, manual sampling is generally used in actual core sampling, which is not only low in sampling efficiency, time-consuming and laborious, but also difficult to guarantee the quality of the core.
