Abstract:Taking for example the Tertiary of the Xihu depression in the East China Sea,the optimal sandstone and mudstone compaction mathematical models have been selected based on the fitting of porosity and depth data and establishment of curvilinear equations.By using the inverision method,volume method and Monte Carlo method.the mudstone compaction water head value and water quantity and the sandstone storage capacity and water exchange in tensity of each layer in each study stage have been calculated,the series graphs of mudstone compaction water head values in the sedimentary system have been drawn and the gravity water vadose field and its evolution process in sandstone reservoirs in a sedimentary system have been reconstructed. |
