Study on Correlation between Carbonate Reservoirs and Transgression or Regression of Sea water,Uplifting or Sinking of Shoal Flat,and Dolomitized Karst——A case study of the Longwangmiao Formation of the Yangtze Platform
There are four types of reservoirs in the carbonate rocks confirmed by the practices of oil and gas exploration and production,namely reef and shoal reservoirs,dolomite reservoirs,erosion( karst) reservoirs,and fracture reservoirs. Therefore,the control factors of the reservoirs play a very important role in the practices. Six main outcrop profiles,2 main well sections,and 81 various information points are analyzed using the methodology of rapid sedimentary facies analysis of the shoal and flat assemblage,...
