ABSTRACT

To foster the exploration and exploitation of oil reservoirs in Northern Shaanxi, an investigation into the attributes of sand bodies and depositional facies within the Yan 8 oil layer formation in Area X was conducted, utilizing core samples, mud logs, and well-logging data. Building upon core descriptions, an analysis was performed on individual-well depositional facies, continuous-well depositional facies, as well as areal depositional facies. It is postulated that the Yan 8 interval in the study region represents a fluvially-dominated delta plain setting, characterized by three primary developments: distributary channels, natural levees, and inter-channel swamps as micro-environments. Vertically, the sand bodies of the Yan 8 oil layer formation are discontinuous, primarily comprising distributary channels and inter-channel swamps. Horizontally, the Yan 8 oil layer formation features 10 river channels, which are arranged in a linear fashion on the plane, extending in a northwest-southeast direction. These channel deposits form the principal framework of the sand body structure and also serve as the main zones for oil and gas accumulation.
