Based on five types of conventional logging curves including GR, RLLD, CNL, DEN and AC, and 39 core samples from 30 representative boreholes, the logging characteristics and lithofacies and sub-facies of the basaltic rocks were studied. Three basaltic facies and four sub-facies are recognized from the well logs, including volcanic conduit facies (post intrusive sub-facies), explosive facies, and effusive lava flow facies (tabular flow, compound flow and hyaloclastite sub-facies). The post intrusive, tabular flow and compound flow subfacies logging curves are mainly controlled by the distribution of vesiculate zones and vesiculate content, which are characterized by four curves with good correlation. Post intrusive sub-facies are characterized by high RLLD, high DEN, with a micro-dentate logging curve pattern, abrupt contact relationships at the top and base. Tabular flow sub-facies are characterized by high RLLD, high DEN, with a bell-shaped log curve pattern, abrupt contact at the base and gradational contact at the top. Compound flow sub-facies are characterized by medium-low RLLD, with a micro-dentate or finger-like logging curve pattern, abrupt contact at the base and gradational contact at the top. Explosive facies and hyaloclastite sub-facies logging curves are mainly controlled by the distribution of the size and sorting of rock particles, which can be recognized by four kinds of logging curves with poor correlation. Explosive facies are characterized by low RLLD, medium-low CNL and low DEN, with a micro-dentate logging curve pattern. Hyaloclastite sub-facies are characterized by low RLLD, high CNL, low DEN and high AC, with a micro-dentate logging curve pattern. The present research is beneficial for the prediction of basaltic reservoirs not only in the Liaohe depression but also in the other volcanic-sedimentary basins.
