| Abstract: | Secondary holes, caverns and fractures are developed in carbonate reservoirs of Jingbian gasfield, and Ordovician palaeokarst is very important for the forming of secondary holes, caverns and fractures. The palaeokarst features and its controlling factors are researched and the controlling mechanism of palaeokarst on reservoirs are furtherdiscussed by use of the core observation data, thin section analysis data and various well test data. The results indicatethat the reservoirs in Jingbian gasfield experien... |
