THE DEEP RESERVOIR EXPLORATION ANALYSIS IN THE GANCHAIGOU REGION OF NORTH AREA OF WESTERN QAIDAM BASIN

摘要: 干柴沟地区位于柴西南区向柴西北区的过渡地带,南部紧邻狮子沟富油凹陷,是柴达木盆地勘探热点地区,但目前还没有获得突破。在综合分析源岩、储层抽提物地化特征的基础上,指出干柴沟地区下干柴沟组上段和上干柴沟组烃源岩丰度高,并处于成熟阶段,具有较高生烃能力;干柴沟深层储层抽提物来自本地下干柴沟组上段烃源岩,但也不排除狮子沟富油凹陷供油的可能性,油源充足。通过对干柴沟构造、储层等特征的分析,指出该地区构造、储层发育,生储盖配置良好,构造深层特别是C3井区具有较好的勘探潜力。Abstract: Ganchaigou area is located in the transition zone from the south to the north of Western Qaidam Basin,which has the Shizigou enriched sag in the southwest.Although it is the hot exploration area of the Qaidam Basin,it doesn't has larger exploration breakthrough.Based on the analysis of the geological and geochemical features of source rock and the reservoir extract,this paper points out that the oil source is sufficient in this area and the feature of reservoir extract of the deep structure is same with that of E23 source rock of the Ganchaigou region and the Shizigou Sag.This paper analyses comprehensively the structure and reservoir features and pointes out that source-reservoir-cap assemblage is good in this area,and deep structure of the Chai 3 well area especially has better oil-gas exploration potential.
