Title: Progress in geophysical logging technology for shale gas researvoirs
Abstract: Shale gas is stored in the shale as gas of adsorbed and free state,so it is a kind of non-convensional resources.Geophysical logging technology has high vertical resolution and sensitivity,and can provide continuous petrophysical information along the borehole,so is an indispensable means of reservoir evaluation of conventional resource as well as unconventional resources.This paper summarizes the geological characteristics of shale gas reservoirs and the logging series for shale gas reservoirs at home and abroad,and discusesses logging response characteristics of shale gas reservoirs.For logging data processing,total organic carbon content (TOC) calculations and maturity index (MI) based on the logging data are derived,and the research progress and calculation methods are given to discuss evaluation method for fractures shale.A case study in Americais taken to in troduce well logging and interpretation of shale reservoirs.Finally,some problems about the shale gas well logging and petrophysical parameter calculation are pointed out,and the breakthroughs and important research direction are also proposed, which is an important guide to shale gas exploration and economy evaluation.
