摘要

After the break of sedimentation from middle Ordovician to early Carboniferous, Lunnan ancient buried hill received deposition again in the middle of Carboniferous. According to the seismic structural explanation and analysis of structural background, the research was carried out upon Ordovician soluble stratum and the distribution of soluble regions to the east of the 7th well in Lungu. In light of impression method and residual thickness method, and through the analysis of corresponding relations between upper and lower strata of ancient weathering crust in the research area, the gap between the bottom of doublet limestone, the symbol stratum in Carboniferous regions, and Ordovician buried hill stratum was filled. By applying impression method and residual thickness method, pre-Carboniferous paleokarst geomorphology in this region was rehabilitated, so as to prepare for the identification of ancient geomorphology. Geomorphic units such as karst highlands, karst gentle slopes and karst peak-cluster valleys were distinguished as alternative objective regions for further reservoir prediction work.
