The evaluating reservoir pore structure quantitatively by using NMR log data has progressed
rapidly in the last five years. It provides novel ideas and methods for geologists to solvs the …

The principle of evaluation of formation pore structure with NMR logs is presented. The effect
of hydrocarbon-bearing reservoir on distribution shape of t2 in NMR logs is discussed. It is …

Formation pore structure generally includes pore geometry, volume, connectivity and other
properties of pore body and pore throat in the reservoir formation. Acquiring continuous pore …

It is very important to understand reservoir pore structure information in finding interested
zones and formulating advisable recovery scheme. Capillary pressure data is critical …

Abstract Evaluation of pore structure and classification are of great significance for tight
reservoirs exploration and development. In this paper, taking the tight gas reservoir of …

Both NMR T2 spectrum and mercury injection analysis of cores can reflect characteristics of
pore structure in rocks. A transformation model from T2 spectrum to pore throat radius …

The traditional reservoir classification methods based on conventional well logging are
inefficient for determining the properties, such as the porosity, shale volume, J function, and …

Both NMR T2 distribution of core and capillary pressure can be used to characterize pore
throat structures of rock to a certain degree. Theoretical analysis gives the correlation …

The evaluation of the pore structure of tight sandstone reservoirs has a significant influence
on the effective exploration and development of tight sandstone oil. Laboratory …

It is crucial to understand the behavior of the T2 distribution in the presence of hydrocarbon
to properly interpret pore size distribution from NMR log. Laboratory measurements of T2 …
