| description | The embodiment of the invention relates to the technical field of underground temperature correction, and discloses an underground T2 spectrum temperature correction method and computing equipment. According to the embodiment of the invention, fitting is carried out on the first T2 spectrum of the target layer according to the Gaussian distribution model to obtain the second T2 spectrum, and temperature correction of the transverse relaxation time is carried out on the feature points of the second T2 spectrum according to the first temperature correction formula to obtain the third T2 spectrum. Correcting the first total nuclear magnetic porosity of the target layer according to a second temperature correction formula to obtain a second total nuclear magnetic porosity at the ground temperature, normalizing the third T2 spectrum to obtain a fourth T2 spectrum, and finally correcting the temperature of the porosity component of the fourth T2 spectrum according to the second total nuclear magnetic porosity to ob |
