Petroleum Exploration History and Enlightenment in Sichuan Basin: A Case Study on Sinopec Exploration Areas

doi:10.7657/XJPG20210304

Abstract

Abstract:

After systematically analyzing the petroleum geological theory and exploration results of the Sinopec exploration areas in the Sichuan basin, we divide the exploration history of the Sichuan basin into three stages: exploration for structural oil and gas reservoirs (1953-2000), exploration for lithologic gas reservoirs (2000-2010), and exploration for both conventional and unconventional oil and gas reservoirs ( from 2010 to present). Taking Puguang, Yuanba and Fuling gas fields as cases, which are three most representative large gas fields discovered by Sinopec in the Sichuan basin in recent two decades, we analyze the problems arising in the early exploration stage, summarize the theoretical innovations, changes of idea, exploration discoveries and follow-up plans. Our findings can be a reference for exploration in other areas or basins.

Key words: Sichuan basin, exploration history, Puguang gas field, Yuanba gas field, Fuling gas field, structural oil and gas reservoir, lithologic gas reservoir, unconventional oil and gas reservoir
