Predict Distribution Of Huimin Hollow Deep-seated Stratum Trellis Characteristic And Sediment System

The paper studied the deep-seated stratum trellis characteristic and the sediment system distribution of the interested zone based on the ordinal stratum principle aiming at the geological characteristic of Huimin hollow.Huimin hollow develops two integrated gradation: Shasi gradation and Kongdian gradation. Huimin hollow deep-seated stratum trellis forward sediment pattern, lens pattern, massif pattern, clutter pattern, blank pattern, weak swing pattern, strong swing pattern and middle swing pattern and so on.Seismic pattern belong to a typical terrene spiccato basin seismic pattern. Craggedness is mainly cuniform clutter pattern, and belong to a near water fan seismic response; gently zone is mainly middle swing pattern and middle-high frequency, and sidelong sediment appears in the gently zone; lake center zone corresponds to a big black pulpy sandstone, has middle-high continuous middle swing matting state and weak swing pattern, sometimes lens seismic pattern or massif pattern appears.Huimin hollow develops half deep lake pattern, fan delta pattern, near shore underwater fan pattern, impulsion fan pattern, seashore lake pattern, bottomland pattern, impulsion champaign pattern and erosion fan pattern and so on.Huimin hollow develops near below underwater fan-half deep lake system, fan delta-half deep lake- erosion fan system, fan delta- shore shallow lake system and alluvium fan-river- alluvium champaign system and so on, and different zone(that is single broken craggedness zone, single broken postpone zone, double broken rift valley zone and lake center zone) corresponds to different sedimental system.Huimin hollow develops three hydrocarbon fountainhead rock, develops three engender-storage-cover combination.
