摘　　要：潜山中生界储层非均质性极强,勘探较少,对其如何精准刻画有效储层进行了重点研究。以兴隆台潜山为例,兴隆台潜山油气源丰富,油气疏导体系完善,多重优越地质条件决定了在有效储层处均能见到良好的勘探效果。针对这一特点,从精细地层格架出发,利用已知井确定中生界各段优势岩性,利用测井响应进行储层定性、成像资料识别,在二次解释和综合地质认识的基础上预测有效储层,反推已知井确定有效储层。突破了以往“中生界储层难追踪”的潜山勘探传统认识,为该类潜山中生界储层的评价提供指导意义。In the past,Mesozoic exploration in buried mountains was limited.This was because the reservoir heterogeneity in the Mesozoic was very strong,and how to accurately identify effective reservoirs is the focus of Mesozoic exploration.This paper takes Xinglongtai buried hill as an example.The geological conditions of Xinglongtai buried hill,including abundant oil and gas sources,perfect oil and gas diversion system,multiple superior geological conditions determine that as long as effective reservoirs are found,and good exploration results can be seen.Aiming at this advantage,the paper starts from fine stratigraphic framework,uses known wells to determine the dominant lithology of Mesozoic sections,uses logging response to identify the qualitative and imaging data of reservoirs,and predicts the effective reservoirs on the basis of secondary interpretation and comprehensive geology.The known well is determined to be an effective reservoir.This study breaks through the traditional understanding of Mesozoic reservoirs which is difficult to trace and provides guidance for the evaluation of Mesozoic reservoirs in Mesozoic buried mountains.
