Problems solved by technology

However, due to the low mechanical strength and large deformation of soft rock, the ensuing problem is that the test sample is not easy to obtain, or the test sample loses representativeness due to excessive disturbance during sampling.

Abstract

The invention provides a preparation mould for a standard manual simulated rock core test piece. The preparation mould for the manual simulated rock core test piece comprises a test piece pressing head, a sleeve, a rock core valve, a mould filling base and a tamping tool. The preparation mould is simple and convenient in preparation method and is convenient to operate; three mechanical properties including compressive strength, elasticity modulus and Poisson ratio of a soft rock can be simulated.

Description

technical field [0001] The invention relates to a mold for preparing artificially simulated rock core specimens, in particular to a mold for preparing standard artificially simulated rock core specimens. Background technique [0002] Nowadays, in the process of onshore and offshore oil and gas exploration and development in my country, more and more soft rocks are encountered. However, due to the low mechanical strength and large deformation of soft rock, the ensuing problem is that the test sample is not easy to obtain, or the test sample loses representativeness due to excessive disturbance during sampling. For these weakly cemented, layered or fractured rocks, the success rate of coring is extremely low, and even if a complete core is obtained, the impact of damage on rock properties is also significantly changed. Contents of the invention [0003] The present invention aims at the above-mentioned defects and provides an artificial simulation core specimen preparation...
