Preparing device and method for artificial rock cores

Abstract

The invention provides a preparing device and method for artificial rock cores. The preparing device comprises pressing plug heads and pressing mold cylinders, and is characterized by also comprisinga heat preservation box, a temperature control device is arranged in the heat preservation box, the pressing plug heads and the pressing mold cylinders are coaxially arranged in the heat preservationbox from top to bottom, and the pressing plug heads can be movably sleeved with the pressing mold cylinders; a jack is arranged outside the heat preservation box, and a threaded rod of the jack is fixedly connected with the tops of the pressing plug heads to drive the pressing plug heads to move inside the pressing mold cylinders; the preparing device also comprises a pressing carrying table and acore taking carrying table; both the pressing carrying table and the core taking carrying table can be arranged at the top ends of the pressing mold cylinders and are used for bearing the pressing mold cylinders; a support for bearing the pressing carrying table and the core taking carrying table is also arranged inside the heat preservation box. The preparing device is simple in structure, convenient to move, small in occupied area and high in production efficiency, the manual operation cost and the economic cost can be reduced, and the artificial rock cores with different sizes can be manufactured and automatically taken out.

Description

technical field [0001] The invention relates to the technical field of underground engineering excavation and development and underground storage of oil and gas, in particular to an artificial core preparation device and a preparation method thereof. Background technique [0002] The physical parameters of rock mass play an extremely important scientific research role in major underground projects, especially those related to the current national strategic oil and gas underground reserves. However, due to the complexity of the extraction process of naturally formed cores and the corresponding costs It is also high, and the utilization rate of extraction is also greatly affected, which has great limitations on the simulation experiment of obtaining the physical parameters of the core. Therefore, artificial cores are generally used instead of natural cores for indoor simulation experiments. Usually, different core physical parameters are studied, and there are also great requi...

AI Technical Summary

Problems solved by technology

These reaction temperature catalysts play a very important role, so the temperature environment model should be closer to reality when making artificial rock cores. At the same time, it is relatively difficult to take cores for underground engineering rock mass research and analysis. At present, artificial rock cores are produced in a single size. And the environment is usually at room temperature
