摘要
Abstract
In recent years,significant breakthroughs have been made in the exploration of Chang 8 tight oil in Yongning Oilfield,becoming a new field for increasing oil and gas reserves and production.Although some industrial oil flows have been discovered,the development of tight oil is progressing slowly,and research on the formation and distribution patterns of tight oil is relatively weak,which restricts the exploration and development of unconventional oil reservoirs.Through core observation,experimental analysis,logging,and production testing data,it is concluded that the main types of source reservoir configuration in the study area are upper source lower storage type,lower source upper storage type,and source reservoir overlapping type.Among them,the upper source lower storage type and lower source upper storage type have discovered relatively abundant tight oil resources.However,the source reservoir overlapping type is not conducive to the enrichment and accumulation of tight oil due to the thin and poor quality of source rocks and reservoirs,as well as insufficient charging power.It is revealed that in the exploration process of tight oil in the Chang 8 section of Yongning Oilfield,it is also necessary to focus on the influence of source reservoir configuration relationship types on the formation of tight oil reservoirs,clarify the rules of oil and gas enrichment,and improve the exploration and development effect of tight oil.关键词
