Description

TECHNICAL FIELD

[0001] The utility model relates to core processing technical field, specifically, relate to a kind of intelligent core drying and geometric parameter measuring device. BACKGROUND

[0002] Core sampling, also known as core drilling sampling, is a sampling work performed on cores or mineral cores obtained by drilling. It generally splits the core into two halves or four parts along the long axis according to a certain sampling length by manual or mechanical method, and then takes one half or one quarter as a sample.

[0003] During the determination of physical parameters such as porosity, permeability and particle size of rock samples, core cleaning and core drying must be performed to remove crude oil, water and their solubles from the core, thereby reducing their impact on the determination of physical parameters. Core drying is performed by a core dryer. The common core dryer usually places the core on a placement plate and generates heat through a heating pipe to cooperate with a wind guide device to maintain the temperature of the dryer at not more than 105℃ for about 8 hours. However, the common core dryer cannot accurately control the drying time. If the drying time is insufficient, water may still exist inside the core. If the drying time is too long, it will consume electricity and time, and may also cause certain safety hazards due to the long-term overload operation of the dryer.

[0004] The measurement of geometric parameters (length, diameter) of the core is also required during the measurement of physical parameters of rock samples and displacement experiments. However, the measurement of core geometric parameters is usually performed by a vernier caliper, which is easily affected by human operation errors and may result in large measurement errors.
