The exploration potential of the bedrock reservoir is notably large, and clarifying the characteristics and main influencing factors of the bedrock reservoir is the premise of predicting the distribution of favourable reservoirs. This study describes the characteristics of bedrock reservoirs in Dongying Sag, Bohai Bay Basin, based on an integrated analysis of cores, thin sections, well logs, image logging, porosity and permeability data and oil testing data. The main influencing factors are determined from the aspect of alteration-destruction-preservation of bedrock weathering crusts based on outcrops, inter-well sections and seismic interpretation. Subsequently, the genetic model of the distribution of the bedrock reservoir is established based on the distribution characteristics of weathering crusts on different structural zones combined with the main influencing factors of weathering crusts. Furthermore, the distribution of favourable reservoirs is determined based on an integrated analysis of reservoir formation and preservation conditions. The main influencing factors and the genetic model of distribution for a bedrock reservoir based on analysis of the alteration-destruction-preservation aspect not only gives us a more comprehensive understanding of the evolution of bedrock reservoirs, but also provides new ideas and theoretical support for further exploration of bedrock reservoirs in other rift basins worldwide.

基岩储层的勘探潜力很大，弄清基岩储层的特征和主要影响因素是预测有利储层分布的前提。本文通过对岩心，薄片，测井，图像测井，孔隙度和渗透率数据以及试油数据的综合分析，描述了渤海湾盆地东营凹陷基岩储层的特征。主要影响因素是根据露头，井间断面和地震解释从基岩风化壳的蚀变-破坏-保存方面确定的。随后，根据风化壳在不同构造带上的分布特征，结合风化壳的主要影响因素，建立了基岩储层分布的遗传模型。此外，基于储层形成和保存条件的综合分析来确定有利储层的分布。通过对蚀变-破坏-保存方面的分析，对基岩储层的主要影响因素和成因模型进行了研究，不仅为我们提供了对基岩储层演化的更全面的认识，也为进一步的研究提供了新的思路和理论依据。勘探世界其他裂谷盆地的基岩储层。基于储层形成和保存条件的综合分析确定有利储层的分布。通过对蚀变-破坏-保存方面的分析，对基岩储层的主要影响因素和成因模型进行了研究，不仅为我们提供了对基岩储层演化的更全面的认识，也为进一步的研究提供了新的思路和理论依据。勘探世界其他裂谷盆地的基岩储层。基于储层形成和保存条件的综合分析确定有利储层的分布。通过对蚀变-破坏-保存方面的分析，对基岩储层的主要影响因素和成因模型进行了研究，不仅为我们提供了对基岩储层演化的更全面的认识，也为进一步的研究提供了新的思路和理论依据。勘探世界其他裂谷盆地的基岩储层。
