Abstract

The invention provides a clamp holder for a nuclear magnetic resonance system, and belongs to the technical field of nuclear magnetic resonance detection. The clamp holdercomprises a clamping main body made of a non-metal material and provided with an accommodating cavity for placing a sample; an annular framework which is arranged on the outer wall of the clamping main body in a sleeving manner, wherein a gap is formed between the annular framework and the outer wall of the clamping main body; and a radio frequency coil which is arranged around the outer wall of the annular framework. The clamping main body is made of a non-metal material, so that interference of paramagnetic substances on nuclear magnetic resonance signals is avoided; the annular framework is arranged on the outer wall of the clamping main body in a sleeving mode, the radio frequency coil surrounds the outer wall of the annular framework, and the radio frequency coil is prevented from bearing pressure in the clamping main body. A gap is formed between the annular framework and the outer wall of the clamping main body, so that heat transfer of the clamping main body to the radio frequency coil is reduced; According to the structure, the radio frequency coil does not need to bear pressure and high heat, so that the radio frequency coil made of a common material can meet the use requirement, and the design cost is low.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance detection, in particular to a holder for a nuclear magnetic resonance system. Background technique [0002] In oil and gas exploration and development and deep rock mass engineering, there is a complex relationship of interaction and mutual restriction among the stress field, temperature field, seepage field and rock mass deformation field of the rock mass in the relevant formation. In the process of rock mass excavation and oil and gas exploitation, in order to avoid catastrophe induced by rock mass due to stress concentration and unloading and the impact of high temperature, high pressure, and high seepage on mining efficiency, it is necessary to take out rock samples from relevant strata to simulate the environment in which the rock is located To measure the porosity, permeability, saturation and other parameters of rock samples. [0003] The NMR holder mostly adopts an all-...
