Method for acquiring logging parameters using nuclear magnetic analysis
A recently granted patent (Publication Number: US11927713B2) discloses a method for acquiring logging parameters related to gas-bearing porosity using a two-dimensional nuclear magnetic logging analysis graph. The method involves utilizing a multi-dimensional nuclear magnetic logging instrument to acquire the graph, determining a gas-bearing region, and summing contour values to calculate the gas-bearing porosity. The graph includes information on oil-bearing, gas-bearing, and water-bearing regions, as well as specific lines for oil, gas, and water.
Furthermore, the method includes acquiring echo signals during logging, performing a two-dimensional inversion calculation, and acquiring the two-dimensional nuclear magnetic D-T2 graph based on transverse relaxation time and diffusion coefficient. Gas-bearing regions are identified based on specific numerical ranges for diffusion coefficient and transverse relaxation time. The method also involves calculating gas saturations for different formations based on the gas-bearing porosity and contour values in the graph, with the results arranged to form gas-bearing porosity and gas saturation curves according to formation depths. Additionally, the patent includes claims for a device and a non-transitory computer readable storage medium storing instructions for implementing the method for acquiring logging parameters as described in the patent.
