Structural interpretation of the lower second submember, Shahejie formation, W79 block, Wenliu area, Dongpu depression, China

摘要

Use techniques of coherence body, dip body, azimuth body, variance body and ants body to implement the fracture structure in the research area and study the fault distribution. Making the fine logging synthetic seismogram in the research area, the authors compare multi-well jointly, and use the time-frequency analysis technology combined with core and logging data to track to explain the target layers. At last, authors make the velocity model and give the structure diagram of target layers by time-depth conversion on the basis of full three-dimensional interpretation and high-precision synthetic seismogram.
