应用勘探层分析及石油资源专家系统对ＸＨ凹陷下第三系勘探目的层的三个勘探层烃资源量作出了综合预测，结果表明，凹陷内各勘探层，尤其是渐新统勘探层，烃资源量相当可观。提出在渐新统内的地层圈闭中可进一步作详细的勘探工作。 Based on the comprehensive prediction of the hydrocarbon resources in the three exploration target reservoirs under the XH depression using exploration layer analysis and petroleum resource expert system, the results show that all the exploration layers in the depression, especially the Oligocene exploration zone, hydrocarbons The amount of resources is considerable. It is suggested that detailed exploration work can be further carried out in the stratigraphic traps within the Oligocene.
