Abstract:Velocity-lithology quantitative interpretation includes 6 steps: 1. lithologic interpretation of well logging data; 2. sampling with the use of acoustic interval transit time weight method; 3. the acquirement of general compaction curve in an area; 4. velocity spectrum interpretation and interval velocity curve smoothing; 5. time-depth conversion using variant velocity; 6. the correction of compaction curve. The interpretation example in Langgu depression shows that velocity-lithology quantitative interpretation can be achieved and sandcontent contour map can be drawn on condition that we have both enough dense velocity spectra (3-5 velocity spectra in each km3at least) and simple geological structure.
