By using a low field nuclear magnetic resonance core analyzer for petroleum core analysis, multiple parameters such as porosity (total porosity, effective porosity, clay bound water porosity, etc.), free fluid index (percentage of movable fluid), pore size distribution, and permeability can be obtained from a rock sample. It has significant advantages in non-destructive testing, multi parameter testing, and same multi parameter testing.

Low field nuclear magnetic resonance core analyzer - desktop nuclear magnetic resonance analyzerBy upgrading the self-developed high-performance spectrometer NmdigI, it was officially launched in 2009. With powerful functions and a compact body, it is currently a cost-effective desktop nuclear magnetic resonance analyzer on the market. It is a domestically produced nuclear magnetic resonance analysis platform; It can meet multiple testing requirements in fields such as petroleum exploration, with objective and accurate measurement results, high accuracy, good repeatability, stable instrument performance, and very high cost-effectiveness.

The measurement method of nuclear magnetic resonance technology itself has many advantages: fast analysis speed, simple and convenient operation, no impact on the health of operators and the surrounding environment, no need for special sample preparation, non-destructive testing, no need for consumables such as chemical reagents, no pollution of samples, and green environmental protection.

The low field nuclear magnetic resonance core analyzer is a powerful, high-precision, high accuracy, and high sensitivity petroleum core analysis instrument based on low field nuclear magnetic resonance technology. This instrument has many powerful functions, including FID, Hahn echo, IR sequence, CPMG sequence and other related measurements, which can meet the basic requirements of pore, permeability and saturation testing in the field of petroleum rock cores. Equipped with independently developed spectrometers, RF amplifiers, and gradient amplifiers, it is currently the most advanced desktop nuclear magnetic resonance analyzer in the market; Can meet the basic laboratory testing needs in the field of petroleum exploration.
