According to the introduction of the hardware advantages of Magnetic Resonance Imaging Logging Prime (MRIL-P) Tool, this paper discusses three core issues of MRIL-P T2 spectrum inversion.  Based on a study of MRIL-P T2 spectrum inversion technology, the authors discuss the effects of spectrum inversion of different lithologies at different SNRs. The conglomerate reservoirs in the Lower Jurassic Zhenzhuchong Formation of JLS structure are characterized by complex lithology, multiple types of reservoir space, low porosity and low permeability, challenging the accurate calculation of logging porosity. Based on the research of MRIL-P T2 spectrum inversion, the authors present a method of optimizing regularization parameters. The results show that MRIL-P is capable of calculating accurate porosity of low permeability and porosity reservoirs.
