Abstract:

In order to further strengthen exploration in China's mature oil and gas regions,researchers studied the distribution of oil and gas reservoirs and residual oil and gas resources in petroliferous depressions and proposed that the key formations as well as those underlying and overlying them in the potential zones of these depressions be the future targets of refined exploration.Based on the analysis of exploration experiences in mature oil and gas regions,they put forward a new idea of refined exploration and established a set of approaches and technologies(including identification and protection of oil and gas layer,prediction of oil and gas reservoirs,oil and gas production enhancement,and etc.) aiming at different kinds of reservoirs and pools.Their wide application has resulted in large reserve growth.Compared with exploration in offshore and frontier areas,refined exploration in mature oil and gas regions has lower cost,shorter period of capital recovery,and higher economic returns.

Key words: hydrocarbon resource potential, petroliferous depression, favorable region, exploration methods and technologies, refined exploration, mature oil and gas region
