摘要
泌阳凹陷位于河南省南部,是东部典型的富油凹陷,然而前人针对其陆相页岩油储层特征、“甜点”层段识别及测井评价方法等研究相对薄弱。为了明确泌阳凹陷核桃园组取心/未取心段页岩油储层特征、优选有利层段,基于实验分析结果与测井资料,系统分析核三段Ⅲ亚段页岩油储层矿物组成、储集性、含油性等特征,重点建立总有机碳含量、孔隙度、可动性评价参数等关键参数测井高精度评价模型。综合评价结果显示,随着埋深增加,核三段页岩油储层脆性、储集性、含油性、可动性均逐渐更好,以2小层底部、3小层储层品质相对最优,具有较好勘探开发前景。
Biyang Depression is located in the south of Henan Province,and is a typical oil-rich depression in the eastern region.However,previous studies on the characteristics,identification of“sweet spots”intervals,and logging evaluation of continental shale oil reservoirs are relatively weak.In order to clarify the characteristics of shale oil reservoir of the Hetaoyuan Formation in the Biyang Depression and select favorable intervals,the mineral composition,reservoir properties,oil content and other characteristics of shale oil reservoirs in the H3ⅢFormation were analyzed based on experimental and logging data.The high-precision logging evaluation model was established for key parameters such as total organic carbon content,porosity,and mobility evaluation parameters.The comprehensive evaluation results show that the burial depth increases,the brittleness,reservoir properties,oil content,and mobility gradually improve,with the bottom of the second layer and the third layer having relatively optimal reservoir quality,and overall have good exploration and development prospects.
