Well Logging Series and Interpretation to Complicated Lithologic Oil/Gas Reservoirs

After some common knowledge introduced with considerable pages about reservoir lithology in Liaohe oilfield,this paper proposes a logging series for igneous,carbonatite and metamorphosed rock reservoir,i.e.: conventional logging series + acoustic and/or electrical imaging logging(combine both or select one) + nuclear magnetic logging(optional in metamorphosed rock) + array acoustic logging+ cross dipole acoustic logging(optional) + spectral logging.4 figures of synthetic interpretation are described.It is believed that the advanced technology of interpretation and evaluation could more effectively identify and evaluate oil and gas reservoirs with complicated lithologies.
